Vasiṣṭha said: “The twenty-fifth principle—the Self—is remembered as the ‘knower’ and is not of the nature of Prakṛti. But when it truly awakens to itself, recognizing its complete difference from Prakṛti, then it becomes ‘kevala’—standing alone in its own pure reality, established in the stainless state of the supreme Brahman.”
वसिष्ठ उवाच
The Ātman (Puruṣa), counted as the 25th principle, is not a product of Prakṛti. Liberation (kevalatva/kaivalya) arises when one directly realizes the Self as distinct from Prakṛti and abides in its own pure consciousness.
In the didactic setting of Śānti Parva, Vasiṣṭha instructs on metaphysical discrimination: he defines the Self as the knowing principle beyond material nature and states that true realization culminates in ‘kevala’—the Self’s independent, purified establishment in Brahman.
