O son of Prtha, know that I am the original seed of all existences, the intelligence of the intelligent, and the prowess of all powerful men.

Bijam means seed; Krishna is the seed of everything. In contact with material nature, the seed fructifies into various living entities, movable and inert. Birds, beasts, men and many other living creatures are moving living entities; trees and plants, however, are inert–they cannot move, but only stand. Every entity is contained within the scope of 8,400,000 species of life; some of them are moving and some of them are inert. In all cases, however, the seed of their life is Krishna. As stated in Vedic literature, Brahman, or the Supreme Absolute Truth, is that from which everything is emanating. Krishna is Parabrahman, the Supreme Spirit. Brahman is impersonal and Parabrahman is personal. Impersonal Brahman is situated in the personal aspect–that is stated in Bhagavad-gita. Therefore, originally, Krishna is the source of everything. He is the root. As the root of a tree maintains the whole tree, Krishna, being the original root of all things, maintains everything in this material manifestation. This is also confirmed in the Vedic literature. Yato va imani bhutani jayante. “The Supreme Absolute Truth is that from which everything is born.” He is the prime eternal among all eternals. He is the supreme living entity of all living entities, and He alone is maintaining all life. Krishna also says that He is the root of all intelligence. Unless a person is intelligent he cannot understand the Supreme Personality of Godhead, Krishna.
