Srimad Bhagavatam Canto 10, Chapter 10, Text 33

SB 10.10.33

tasmai tubhyam bhagavate
vasudevaya vedhase
atma-dyota-gunais channa-
mahimne brahmane namah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
O Lord, whose glories are covered by Your own energy, You are the Supreme Personality of Godhead. You are Sankarsana, the origin of creation, and You are Vasudeva, the origin of the caturvyuha. Because You are everything and are therefore the Supreme Brahman, we simply offer our respectful obeisances unto You.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Instead of trying to understand Krsna in detail, it is better to offer our respectful obeisances unto Him, for He is the origin of everything and He is everything. Because we are covered by the material modes of nature, He is very difficult for us to understand unless He reveals Himself to us. Therefore it is better for us to acknowledge that He is everything and offer obeisances unto His lotus feet.
