Abstract
In the twentieth century, the rise of environmental challenges alongside the spread of philosophical phenomenology gave birth to eco-phenomenology—an approach that can serve in comparative philosophy as a key to cross-cultural convergence in confronting humanity's self-inflicted crises. The present study offers a comparative phenomenological analysis of nature in two Eastern philosophical traditions: Advaita Vedānta and Ṣadrian Transcendent Theosophy. The central research question is: what phenomenological relationship do these two ontological systems hold with respect to their understanding of nature? To this end, after elucidating the philosophical insights of Mullā Ṣadrā and the Advaita Vedānta school regarding nature, a comparative phenomenological analysis is presented. The aim is to analyze these two schools phenomenologically and thereby lay the groundwork for developing a cross-cultural philosophical framework for environmental ethics. The findings reveal that, despite their divergent origins, these two traditions share remarkable commonalities in fundamental principles such as belief in the unity of existence, emphasis on intuitive knowledge as the path to salvation, and the pursuit of absolute reality as the axis of being. Both schools reject a purely instrumental and materialistic view of nature and accord it intrinsic value. By linking humanity and nature to a transcendent reality, these ontological perspectives provide rich theoretical foundations for environmental ethics and can strengthen the motivation needed for environmental preservation and the transition beyond destructive modern attitudes. This study paves the way for deeper cross-cultural dialogues and the development of inter-civilizational environmental ethics.

Introduction
The growing ecological crises of the contemporary world—climate change, biodiversity loss, environmental degradation, and the exploitation of natural resources—have prompted urgent calls for philosophical reflection on the relationship between human beings and nature. In response to these challenges, the field of environmental ethics has emerged as a vital area of philosophical inquiry, seeking to articulate normative frameworks that can guide human action toward more sustainable and respectful engagement with the natural world. At the same time, the phenomenological method, with its emphasis on lived experience and the suspension of presuppositions, has offered new possibilities for understanding how human beings directly experience and interpret their environment. The convergence of these concerns has given rise to "ecophenomenology," a field that seeks to recover a more authentic and immediate experience of nature, free from the distorting lens of purely instrumental and scientific approaches.
Within this context, comparative philosophy offers a promising avenue for enriching environmental ethics by drawing upon the wisdom traditions of non-Western cultures. The present study undertakes a comparative phenomenological analysis of nature as conceived in two major philosophical traditions: the transcendent philosophy (al-ḥikma al-muta'āliya) of Mullā Ṣadrā (d. 1635), the preeminent figure of Islamic philosophy, and the Advaita Vedānta school of Hindu philosophy, as articulated by its foundational thinker Śaṅkara (c. 8th century CE). Both traditions, despite their distinct cultural and historical origins, offer profound and sophisticated ontologies that challenge the reductive materialism and anthropocentrism that have come to dominate modern Western thought.
The central research question guiding this study is: How can the phenomenological analysis of nature in the ontological frameworks of Mullā Ṣadrā and Advaita Vedānta be compared, and what are the implications of these frameworks for the development of a cross-cultural environmental ethics? The study argues that both philosophical systems, through their respective doctrines of the unity of existence, the dynamic and sacred character of nature, and the centrality of intuitive knowledge, provide robust theoretical foundations for an environmental ethic that recognizes the intrinsic value of nature and the profound interconnectedness of all beings.
The significance of this research lies in its potential to bridge Eastern and Western philosophical traditions in service of a shared global concern—the protection and preservation of the natural environment. By identifying points of convergence between Islamic and Hindu thought on the nature of reality and the place of nature within it, the study contributes to the development of a genuinely intercultural environmental ethics that can draw upon the moral and spiritual resources of multiple traditions. This approach not only enriches philosophical understanding but also provides practical motivation for environmental stewardship, grounded in a deep appreciation of nature as a manifestation of the sacred.

Research Methodology
This research employs a comparative phenomenological methodology to analyze the ontological conception of nature in two philosophical traditions: Mullā Ṣadrā's transcendent philosophy and the Advaita Vedānta school of Hindu philosophy. The research proceeds through several systematic stages.
The first stage involves a comprehensive exposition of each tradition's philosophical foundations regarding nature. For Mullā Ṣadrā, this includes examination of his core doctrines of the principiality of existence (iṣālat al-wujūd), the gradation of existence (tashkīk al-wujūd), substantial motion (ḥaraka jawhariyya), and the concept of nature as a manifestation of divine names and attributes. Primary sources consulted include Ṣadrā's magnum opus al-Asfār al-arba'a (The Four Intellectual Journeys), his al-Mabda' wa al-Ma'ād (The Origin and the Return), and other key works. For Advaita Vedānta, the analysis focuses on Śaṅkara's commentaries on the principal Upaniṣads, the Brahma-sūtras, and the Bhagavad-gītā, as well as the foundational concepts of Brahman (ultimate reality), Ātman (the true self), and Māyā (the cosmic illusion or creative power). Secondary literature from both traditions is consulted for contextualization and clarification.
The second stage involves comparative phenomenological analysis, examining the two traditions across four key thematic dimensions: (1) the ontological status of nature and its relationship to ultimate reality; (2) the epistemological methods for attaining knowledge of nature's true nature; (3) the teleological orientation of the spiritual journey and the role of nature within it; and (4) the implications of each ontology for environmental ethics and practice. This analysis identifies both convergences and divergences between the two frameworks, using phenomenological concepts such as intentionality, lived experience, and the bracketing of presuppositions as analytical tools.
The third stage synthesizes the findings and draws implications for the development of a cross-cultural environmental ethics. The research employs a hermeneutical approach, interpreting the philosophical texts not merely as historical artifacts but as living resources that can speak to contemporary concerns. Throughout the analysis, the study maintains a balanced approach, neither forcing the traditions into artificial agreement nor exaggerating their differences, but allowing each to speak in its own voice while identifying genuine points of resonance and complementarity.

Discussion
Mullā Ṣadrā's Ontology: Nature as a Dynamic and Sacred Order
Mullā Ṣadrā's philosophical system is founded upon the principle of the principiality of existence (iṣālat al-wujūd), which marks a decisive departure from the earlier Islamic philosophical emphasis on quiddity (māhiyya). According to this doctrine, existence is the sole genuine reality in the external world; quiddities are merely conceptual limitations that the mind imposes upon existence. Existence is not a static, uniform reality but a graded, dynamic continuum that extends from the necessary existence of God, through the various levels of contingent existence, down to the lowest degree—material nature. This gradation (tashkīk) means that all beings participate in the same reality of existence but to different degrees, much as light admits of varying intensities while remaining essentially light.
Within this graded ontological framework, nature occupies the lowest level of existence, characterized by materiality, change, and potentiality. However, this does not mean that nature is insignificant or illusory. On the contrary, as a genuine mode of existence, nature is a real manifestation of the divine reality. In Ṣadrā's conception, which is often interpreted through the lens of "gradational unity of existence" (waḥdat al-wujūd al-tashkīkiyya), all beings are interconnected within a single continuum of existence. Even in the more radical interpretation of "personal unity of existence" (waḥdat al-wujūd al-shakhṣiyya), nature is not dismissed as mere illusion but understood as a manifestation (ẓuhūr) and appearance of the one reality. Thus, while nature may be the lowest level of existence, it is by no means divorced from the higher levels; rather, it participates in and reflects the same fundamental reality.
A second cornerstone of Ṣadrā's ontology is his doctrine of substantial motion (ḥaraka jawhariyya). Traditional Aristotelian philosophy had limited change to the category of accidents—the qualities and attributes of substances could change, but substances themselves remained fixed. Ṣadrā radically transformed this view by asserting that change penetrates the very substance of things; the essence of a being is itself in a state of continuous becoming and transformation. Nature, on this view, is not a static collection of inert objects but a dynamic process of perpetual self-transformation toward ever higher degrees of perfection. Every natural entity—from minerals to plants, animals, and humans—is engaged in an ongoing journey of becoming, moving from potentiality to actuality, from lower to higher levels of existence. This understanding imbues nature with a sacred, purposeful character; it is not a mere resource to be exploited but a living, evolving manifestation of divine wisdom.
Third, Ṣadrā interprets nature as a mirror reflecting the divine names and attributes. According to this view, every natural phenomenon is a sign (āya) of God, a locus of divine manifestation (tajallī). The beauty, order, and complexity of the natural world are not accidental features but expressions of the divine beauty, order, and wisdom. To contemplate nature is to contemplate the divine; to respect nature is to respect the divine presence that manifests through it. This understanding transforms the human relationship with nature from one of domination and exploitation to one of reverence, gratitude, and responsibility. Nature is not an alien other to be conquered but a sacred text to be read and understood.
Fourth, Ṣadrā's anthropology situates human beings within this cosmic order as the most comprehensive manifestation of the divine names. Human beings are not external to nature but emerge from it and remain deeply connected to it. The human soul, according to Ṣadrā's doctrine of "the bodily origination and spiritual subsistence of the soul" (ḥudūth jismānī wa baqā' rūḥānī), is initially generated within the material body but through its spiritual development can transcend the limitations of materiality. The perfection of the human being requires the perfection of the body and the proper engagement with the material world. Thus, nature serves as the necessary arena for human spiritual development; it is the "crucible of spiritual perfection." The human being, as God's vicegerent (khalīfa), bears a profound responsibility to care for nature and to maintain its balance and integrity.
Advaita Vedānta: Nature as the Veil of Brahman
Advaita Vedānta, as articulated by Śaṅkara, presents a non-dualistic ontology in which Brahman—the ultimate, infinite, and unchanging reality—is the sole true existent. The phenomenal world, including what we call nature, is not ultimately real but is a product of Māyā, a cosmic power or creative force that both conceals the true nature of Brahman and projects the appearance of multiplicity and differentiation. The concept of Māyā is central to understanding the Advaitic view of nature.
Māyā is a complex and nuanced concept with multiple levels of meaning. In its earliest Vedic usage, it signified "extraordinary power" or "creative ability." In Advaita Vedānta, it takes on the sense of "that which is not" (in the sense of being non-ultimately real) or the cosmic illusion that creates the appearance of a world separate from Brahman. Māyā is described as "neither real nor unreal" (sadasadvilakṣaṇa); it is not real because it does not persist through all states of consciousness, but it is not completely unreal because it is experienced. The world of nature, as perceived through ordinary consciousness, is a construction of Māyā, a superimposition on the underlying reality of Brahman.
This does not mean that nature is entirely unreal in the sense of being non-existent; rather, it is not ultimately real. It has a pragmatic reality (vyāvahārika-sattā) that allows it to function as a sphere of action and experience, but it lacks transcendental reality (pāramārthika-sattā). The distinction is analogous to the difference between a dream and waking consciousness: the dream is experienced and has a kind of reality while it lasts, but upon waking, one recognizes it as a mere projection of the mind. Similarly, upon attaining true knowledge (vidyā), the Advaitin recognizes the phenomenal world as a projection of ignorance (avidyā) and realizes the non-dual nature of reality.
Śaṅkara illustrates the concept of Māyā through familiar examples of perceptual error: mistaking a rope for a snake, or a piece of mother-of-pearl for silver. In these cases, the perceived object (the snake or silver) is not completely real (there is no snake or silver present), but the perception is not completely unreal either (there is something present that is perceived erroneously). The error arises from ignorance—a failure to recognize the true nature of what is actually present. Similarly, our perception of a multiplicity of objects in nature arises from ignorance of the underlying unity of Brahman. When the veil of ignorance is removed through knowledge, the apparent multiplicity dissolves into the unity of Brahman.
The Advaitic view of nature thus presents a profound epistemological and ethical challenge. If nature is ultimately an illusion, why should we care for it? Why protect what is ultimately unreal? The Advaitic response to this challenge is subtle and nuanced. First, the Advaitic path to liberation (mokṣa) is not a rejection of the world in a nihilistic sense but a transcendence of attachment to the world. The Advaitin seeks to realize the unity of all beings in Brahman, and this realization entails a deep respect for all manifestations of the one reality. Second, Śaṅkara emphasizes the importance of karma (action) and dharma (righteousness) in the stage of preparation for knowledge. Ethical action in the world, including care for nature, is a necessary part of the spiritual path, even if the ultimate goal transcends the world. Third, the Advaitic emphasis on the unity of all beings implies an ethic of non-harm (ahiṃsā) and compassion that extends to all living beings, recognizing the same divine presence in all.
Comparative Phenomenological Analysis: Convergences and Divergences
The comparative phenomenological analysis reveals both significant convergences and important divergences between the two ontological frameworks. First, regarding the unity of existence, both traditions affirm a fundamental unity underlying the apparent multiplicity of the world. For Ṣadrā, this unity takes the form of a graded continuum of existence in which all beings participate to varying degrees; for Śaṅkara, it is an absolute non-duality in which Brahman alone is real and all multiplicity is ultimately illusory. Despite this difference, both traditions reject the atomistic, reductive materialism that characterizes much modern Western thought and affirm the essential unity and interconnectedness of all things. The metaphors employed by both traditions—shadow, reflection, manifestation, dream—are strikingly similar, suggesting a common phenomenological insight into the relationship between the ultimate and the apparent.
Second, regarding the epistemic method for grasping ultimate reality, both traditions emphasize the centrality of intuitive, experiential, and transformative knowledge. Ordinary sensory perception and rational argument are recognized as necessary but ultimately insufficient for attaining true understanding. Both traditions point to a form of direct, non-discursive, and transformative intuition (shuhūd in Islamic mysticism; jñāna in Advaita) that transcends the limitations of ordinary knowing and brings the aspirant into direct contact with ultimate reality. This emphasis on experiential knowledge is consistent with the phenomenological emphasis on lived experience and the bracketing of theoretical presuppositions.
Third, regarding the goal of the spiritual journey, both traditions define liberation or perfection in terms of the realization of one's true nature and the overcoming of ignorance. For Ṣadrā, human perfection consists in becoming a "rational world" that reflects all the truths of existence, ultimately attaining union with the divine. For Śaṅkara, liberation consists in the realization of one's identity with Brahman and the dissolution of the illusion of separateness. In both traditions, nature serves as the arena or pathway for this spiritual journey; it is not to be rejected but to be understood, respected, and ultimately transcended.
Fourth, regarding the ethical implications for environmental ethics, both traditions provide robust foundations for an ethics of respect and care for nature. Although Advaita Vedānta views nature as ultimately illusory, its emphasis on unity, non-harm, and compassion, combined with its recognition of the world as a legitimate sphere of ethical action, supports an environmental ethic that recognizes the intrinsic value of all beings. Ṣadrā's emphasis on nature as a divine manifestation, a mirror of divine names and attributes, and the necessary arena for spiritual development provides an even more direct foundation for environmental stewardship. Both traditions reject the purely instrumental view of nature characteristic of modern Western thought and affirm the sacred dimension of the natural world.
The principal divergence between the two traditions lies in their respective assessments of nature's ontological status. For Ṣadrā, nature is genuinely real, though ontologically inferior to higher levels of existence; for Śaṅkara, nature is pragmatically real but ultimately illusory. This difference has practical implications: Ṣadrā's view provides a more straightforward basis for environmental activism, while Advaita's view demands a more subtle integration of engagement with the world and detachment from it. However, both views can and do support an environmental ethic, grounded in respect for the divine presence in all things.

Conclusion
This comparative phenomenological study of nature in Mullā Ṣadrā's transcendent philosophy and Advaita Vedānta has revealed significant convergences between these two Eastern ontological traditions, with important implications for the development of a cross-cultural environmental ethics. The analysis has identified four key areas of resonance.
First, both traditions affirm the fundamental unity of existence, rejecting the reductive materialism and atomism that have come to dominate modern Western thought. Nature, in both frameworks, is not a collection of inert objects but a manifestation of a single, sacred reality. Second, both emphasize the centrality of intuitive, experiential knowledge as the path to true understanding. Ordinary sensory perception and rational argument are necessary but insufficient; authentic knowledge requires a transformative, direct encounter with reality. Third, nature serves as the arena or pathway for spiritual development in both traditions; it is not to be rejected but to be engaged with wisely and respectfully as a means of attaining ultimate perfection. Fourth, both traditions provide robust foundations for an environmental ethics that rejects the purely instrumental view of nature, recognizing the intrinsic value and sacred character of the natural world.
While the two traditions differ in their assessment of nature's ontological status—Ṣadrā affirming the genuine reality of nature (though at the lowest level of existence) and Śaṅkara regarding nature as ultimately illusory—both can and do support an ethic of respect, care, and stewardship. Ṣadrā's view provides a more direct ontological basis for environmental activism, while Advaita's view demands a more subtle integration of engagement and detachment. However, the practical implications of both frameworks converge in their rejection of exploitation and their affirmation of the sacred character of the natural world.
These findings suggest that the philosophical resources of Eastern traditions can make a vital contribution to the development of a genuinely intercultural environmental ethics. By drawing upon the wisdom of Islamic and Hindu thought, we can articulate ethical frameworks that are not only philosophically sound but also spiritually motivating, grounded in a deep appreciation of nature as a manifestation of the divine. This approach offers a powerful alternative to the purely utilitarian and economic rationales that have proven insufficient to address the ecological crises of our time. Future research might extend this comparative analysis to include other Eastern and Western traditions, exploring the practical implications of these ontologies for environmental policy, education, and practice.
