He does not see. He does not know that Kṛṣṇa can eat simply by His glance, by seeing. He eats. Because He says in the Bhagavad-gītā that patraṁ puṣpaṁ phalaṁ toyaṁ yo me bhaktyā prayacchati tad aham aśnāmi (BG 9.26). Is He speaking lies? No. He eats, but we do not know His eating process. We compare Kṛṣṇa as ourself. If one plate is given to me, I immediately devour the whole thing. But Kṛṣṇa, He is complete. He can eat the complete; still it remains complete. Pūrṇasya pūrṇam ādāya pūrṇam eva avaśiṣyate (Īśo Invocation).
So in this way we have to understand Kṛṣṇa from the śāstra, from the Vedas. Then we shall understand Kṛṣṇa. And once we understand Kṛṣṇa, our life is successful. Janma karma me divyaṁ yo jānāti tattvataḥ. Anyone who understands Kṛṣṇa in truth, his life is perfect. Tyaktvā dehaṁ punar janma naiti (BG 4.9). The perfection of life is that after giving up this body, we shall not accept any more material body. That is perfection. The people do not know that.
