SB 10.88.10
tad brahma paramam suksmam
cin-matram sad anantakam
vijñayatmataya dhirah
samsarat parimucyate
Translation:
A person who has thus become sober fully realizes the Absolute as the highest truth, the most subtle and perfect manifestation of spirit, the transcendental existence without end. In this way realizing that the Supreme Truth is the foundation of his own existence, he is freed from the cycle of material life.
