Leela is the practice of playing the game of life consciously as well as the basic nature of the divine.
Leela is the nature of Supreme Consciousness, playful nature. The phenomenal world is manifested Leela. The play is beginningless - as well as endless.
Spiritual devotion (bhakti loka) is the great discovery of Leela, created by maya of Supreme Consciousness in order to enjoy Himself - to play hide and seek with Himself. There is no purpose and no responsibility in Leela.

In the words of Maharishi Raman: "The ideas of purpose and responsibility are purely social in nature and are created by mind to exhort Ego. God is above all such ideas. If God is immanent in all and there is no one except him, who is responsible for whom? Creation is expression of inherent laws in the source of creation."
