This verse describes the culmination of disciplined yogic practice, emphasizing the nirvikalpa state – a state of mind devoid of modifications or distractions. The yogi who has achieved this stillness, whose samādhi is characterized by the “yoga-vyutama” – the most accomplished in yoga – truly embodies liberation. The phrase brahmabhuto – “becomes Brahman” – signifies not merely a final state of being, but a fundamental transformation where the individual self ceases to exist as a separate entity. This is not a passive absorption but an active bhava, a becoming of the liberated consciousness into the boundless nature of Brahman, without any possibility of doubt (na san-shay:) – a key indicator of genuine realization. The verse powerfully demonstrates the intimate connection between sustained meditative practice and the ultimate liberation of consciousness.
