Kalpa vriksha Tree

Banyan Tree

Of all trees I am the banyan tree, and of the sages among the demigods I am Nārada. Of the Gandharvas I am Citraratha, and among perfected beings I am the sage Kapila.
(BG 10.26)
The banyan tree (aśvattha) is one of the highest and most beautiful trees, and people in India often worship it as one of their daily morning rituals.
(BG 10.26 purport)

The small fruit of a banyan contains hundreds of seeds, and in each seed is the potency to produce another banyan tree with the potency to produce millions more of such fruits. This law of nature is visible before us, although how it works is beyond our understanding. This is but an insignificant example of the potency of Godhead; there are many similar phenomena that no scientist can explain.
(CC Adi 5.14)

The Blessed Lord said: There is a banyan tree which 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.
(BG 15.1)
