SB 10.10.32
grhyamanais tvam agrahyo
vikaraih prakrtair gunaih
ko nv iharhati vijñatum
prak siddham guna-samvrtah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O Lord, You exist before the creation. Therefore, who, trapped by a body of material qualities in this material world, can understand You?
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As it is said:
atah sri-krsna-namadi
na bhaved grahyam indriyaih
sevonmukhe hi jihvadau
svayam eva sphuraty adah
(Bhakti-rasamrta-sindhu 1.2.234)
Krsna’s name, attributes and form are Absolute Truth, existing before the creation. Therefore, how can those who are created that is, those entrapped in bodies created of material elements understand Krsna perfectly? This is not possible. But, sevonmukhe hi jihvadau svayam eva sphuraty adah: Krsna reveals Himself to those engaged in devotional service. This is also confirmed in Bhagavad-gita (18.55) by the Lord Himself: bhaktya mam abhijanati. Even the descriptions of Krsna in Srimad-Bhagavatam are sometimes misunderstood by less intelligent men with a poor fund of knowledge. Therefore, the best course by which to know Him is to engage oneself in pure devotional activities. The more one advances in devotional activities, the more one can understand Him as He is. If from the material platform one could understand Krsna, then, since Krsna is everything (sarvam khalv idam brahma), one could understand Krsna by seeing anything within this material world. But that is not possible.
maya tatam idam sarvam
jagad avyakta-murtina
mat-sthani sarva-bhutani
na caham tesv avasthitah
(Bg. 9.4)
Everything is resting on Krsna, and everything is Krsna, but this is not to be realized by persons on the material platform.
