The Supreme Personality of Godhead said: "It is said that there is an imperishable banyan tree that has its roots upward and its branches down and whose leaves are the Vedic hymns. One who knows this tree is the knower of the Vedas". -Bhagavad Gita 15.1
This tree’s roots grow upward because they begin from where Brahma is located, the topmost planet of this universe. If one can understand this indestructible tree of illusion, then one can get out of it.
