Exploring the Sāṅkhya Proofs for Puruṣa’s Existence: A Philosophical and Critical Analysis

Abstract Sāṅkhya philosophy is one of the oldest and most systematic attempts in Indian thought to explain reality in a logical way using metaphysical dualism. The main idea behind this is the difference between Puruṣa, which stands for the principle of pure consciousness, and Prakṛti, which stands for the unconscious material substrate of the universe. The existence of Puruṣa is not merely asserted but is strongly substantiated by five philosophical reasons, known as the pañca-hetavaḥ, as articulated in Īśvarakṛṣṇa’s Sāṅkhya Kārikā. This paper offers a thorough analytical evaluation of these five arguments, scrutinising their logical structure, philosophical underpinnings, and metaphysical implications. It also looks at how they fit into Indian epistemology, how they relate to other philosophical schools of thought like Buddhism and Advaita Vedānta, and how significant they are to modern debates about consciousness and the mind-body problem.
