Visvarupa Darsana Yoga-Bhagavad Gita Chapter 11 [The Vision of the Universal Form]
Krishna siad Said > Shaloka: 32
The Blessed Lord said: Time I am, destroyer of the worlds, and I have come to engage all people. With the exception of you [the Pandavas], all the soldiers here on both sides will be slain.
Although Arjuna knew that Krishna was his friend and the Supreme Personality of Godhead, he was nonetheless puzzled by the various forms exhibited by Krishna. Therefore he asked further about the actual mission of this devastating force. It is written in the Vedas that the Supreme Truth destroys everything, even Brahma. Yasya brahma ca ksatram ca ubhe bhavata odanah/mrtyur yasyopasecanam ka ittha veda yatra sah. Eventually all the brahmanas, ksatriyas and everyone else are devoured by the Supreme. This form of the Supreme Lord is an all-devouring giant, and here Krishna presents Himself in that form of all-devouring time. Except for a few Pandavas, everyone who was present in that battlefield would be devoured by Him.
