Agni is recongnized by the Vedic seers as of fundamental importance in man's journey. Agni is the aspiration, and as such it is the priest (Purohita) that kindles the fire of aspiration and initiates man's journey. Agni is the soul, that which guides from within and illumines the path of the journey. Agni is the all pervading energy and heat in the earth and in the heaven and it has the secret power of uniting the light of the heaven and the heat of the matter. It is thus the secret power of physical transmutation.
