3.2.9

sa yo ha vai tat paramaṃ brahma veda brahmaiva bhavati.
nāsyābrahmavit
kule bhavati.
tarati śokaṃ tarati pāpmānaṃ guhāgranthibhyo vimukto 'mṛto
bhavati.

9. He, verily, who knows that supreme Brahma, becomes very Brahma. In his family no one ignorant of Brahma arises. He crosses over sorrow. He crosses over sin (_pāpman_). Liberated from the knots of the heart, he becomes immortal.
