vatsan palams ca visva-vit
sarvam vidhi-krtam krsnah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When Krsna was unable to find the calves and their caretakers, the cowherd boys, anywhere in the forest, He could suddenly understand that this was the work of Lord Brahma.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Although Krsna is visva-vit, the knower of everything happening in the entire cosmic manifestation, as an innocent child He showed ignorance of Brahma’s actions, although He could immediately understand that these were the doings of Brahma. This pastime is called brahma-vimohana, the bewilderment of Brahma. Brahma was already bewildered by Krsna’s activities as an innocent child, and now he would be further bewildered.
