the holy fig tree, important in both Hindu and Buddhist traditions. This tree, which lives for a very long time, is the basis for the image of the Tree of Eternity in the Upanishads — the cosmic tree with its root above, in God, and its branches here below on earth.
Easwaran identifies the fig tree as the sacred Ashvattha, the living archetype of the Upanishadic Tree of Eternity, rooting cosmic unity in the image of interdependent organic life.
