Sri Isopanisad Mantra 8
sa paryagāc chukram akāyam avraṇam
asnāviram śuddham apāpa-viddham
kavir manīṣī paribhūḥ svayambhūr
yāthātathyato 'rthān vyadadhāc chāśvatībhyaḥ samābhyaḥ
Such a person must factually know the greatest of all, the Personality of Godhead, who is unembodied, omniscient, beyond reproach, without veins, pure and uncontaminated, the self-sufficient philosopher who has been fulfilling everyone's desire since time immemorial.
