Avatara

"Avatara" is a collection of twenty-eight essays describing bhakti-yoga, the science of self-realization, and Krishna consciousness based off select verses from sacred Vedic texts like Bhagavad-gita, Ramayana, Chaitanya Charitamrita, and others. "The avatara, or incarnation of Godhead, descends from the kingdom of God for material manifestation. And the particular form of the Personality of Godhead who so descends is called an incarnation, or avatara.
Such incarnations are situated in the spiritual world, the kingdom of God. When they descend to the material creation, they assume the name avatara." (Chaitanya Charitamrita, Madhya 20.263-264)
