From Vedic age, Agni is a god of divine knowledge, who leads man to the gods. Agni has three forms: ‘fire’, ‘lightning’ and the ‘Sun’. Agni is second only to Indra in the power and importance attributed to him in Vedic mythology. Agni is the eldest son of Brahma. In the Visnu Purana, Agni, called Abhimāni is said to have sprung from the mouth of the Virat purusha, the Cosmic Man. In another version, Agni is the son of Dharma (Eternal Law) and Vasubhāryā (daughter of Light). Accroding to Ayurveda Agni is the fiery metabolic energy of digestion, allows assimilation of food while ridding the body of waste and toxins, and transforms dense physical matter into subtle forms of energy the body needs.
