Dvādaśa-prakaraṇam (Kuṇḍalinī) · Verse 3

अष्टाङ्गयोगसंयुक्तो योगी याति परं पदम् । निर्वाणमक्षयं शान्तिं ब्रह्मभूतो भवेत् सदा ॥

aṣṭāṅgayogasaṃyukto yogī yāti paraṃ padam | nirvāṇamakṣayaṃ śāntiṃ brahmabhūto bhavet sadā ||

Here, Yājnavalkya describes the culmination of disciplined practice within the eight-limbed yoga – the attainment of nirvāṇa, that indestructible state of non-duality. The yogī, through consistent engagement with these practices, achieves a state beyond description, a transcendence of all phenomena. The concept of nirvāṇa as akshya (indestructible) suggests a permanence, a fundamental truth that remains unaffected by the fluctuations of the world of appearances. Crucially, the verse states that the yogī “always becomes identified with Brahman,” signifying a complete dissolution of the individual self (ātman) into the ultimate reality. This is not a passive absorption, but an active recognition of the inherent unity between the individual and the divine, a core tenet of both the Upanishads and the later development of Advaita Vedanta philosophy, and a key element in the path to moksha or liberation.
