The Ramayana is in its ethical intention the parable of an enormous conflict between the Deva in human form and the incarnate Rakshasa, between the representative of a high culture and Dharma and a huge unbridled force and gigantic civilisation of the exaggerated Ego. The Mahabharata, of which the Gita is a section, takes for its subject a lifelong clash between human Devas and Asuras, the men of power, sons of the Gods, who are governed by the light of a high ethical Dharma and others who are embodied Titans, the men of power who are out for the service of their intellectual, vital and physical ego. The ancient mind, more open than ours to the truth of things behind the physical veil, saw behind the life of man great cosmic Powers or beings representative of certain turns or grades of the universal Shakti, divine, titanic, gigantic, demoniac, and men who strongly represented in themselves these types of nature were themselves considered as Devas, Asuras, Rakshasas, Pisachas. - Essays on the Gita, pg 470
