That knowledge which is existing beyond this planet and in other universes is called universal knowledge. That knowledge which cannot exist beyond this planet is called non-universal, and thus man-made knowledge.
Only the Vedic scriptures exist beyond this planet and thus the Vedic knowledge is universal. In this universe, the Vedic knowledge was first imparted to Brahma at the beginning of creation. This was 155.522 trillion years ago. The Vedic knowledge is also established in millions of other universes.
“O great one, you pervade from outer space to Earth in all directions, seeing you in this wonderful and terrifying form of yours, all the planetary systems are disturbed.”(Arjuna to Lord Krishna, Bhagavad-Gita 11.20)
Only the Vedic knowledge is eternal and universal. This is because it comes from God, Lord Krishna.
