For the Tree of this Cosmos, the Divine Atma is the Root. This is the purport of the statement in the Gita: “I am the Seed of all living beings.” How is God the Seed and how does He become the Seed in all beings? When we enquire into this we can see that when we plant a seed in the earth, it sprouts, grows into a plant and bears numerous fruits in each of which there is a seed. Out of one seed have come numerous fruits with seeds within them. The seeds in the fruits belong to the same variety as the original seed.

-Bhagavan Sri Sathya Sai Baba
