Kṛṣṇa has no material eyes, but He does have spiritual eyes by which He can see everything and anything. Although He has no material ears, He can hear everything and anything. Having perfect senses, He knows past, future and present. Indeed, He knows everything, but no one can understand Him, for by material senses He cannot be understood. Being the origin of all emanations, He is the supreme, the greatest, the Personality of Godhead.
There are many similar Vedic hymns which definitely establish that the Supreme Absolute Truth is a person who is not of this material world. For instance, in the Hayaśīrṣa-pañcarātra it is explained that although in each and every Upaniṣad the Supreme Brahman is first viewed as impersonal, at the end the personal form of the Supreme Lord is accepted.
