Sages whose faults have worn away, whose doubts are cut off, whose selves are disciplined, and who delight in the welfare of all beings, attain the nirvana of Brahman.
Explanation
Krishna continues describing those who reach liberation, the nirvana of Brahman (brahmanirvāṇa), a state of freedom and peace in the ultimate reality. He names four marks of such sages: their impurities (kalmaṣa) are gone, their doubts or sense of duality (dvaidha) are resolved, they have self-control (yatātman), and they care for the good of all beings. Traditions differ on whether 'cut-off duality' means ending inner doubt or seeing no separation between self and Brahman.
