Nisachar, “Lord Agni”
Agni in Sanskrit means fire and is the name of the Vedic fire god. Agni is also one of the guardian deities of direction, who is typically found in the southeast corners of Hindu temples. In classical cosmology, Agni as fire has been one of the five inert impermanent constituents, Dhatus, along with space: Akasa, water: Ap, air: Vayu, and earth: Prithvi. The five combine to form the empirically perceived material existence or Prakriti.
In the Vedic literature, Agni is a major and oft invoked god along with Indra and Soma. Agni is considered as the mouth of the gods and goddesses, and the medium that conveys offerings to them in a home or votive ritual. He is conceptualized in ancient Hindu texts to exist at three levels, on earth as fire, in atmosphere as lightning, and in the sky as sun. This triple presence connects him as the messenger between gods and human beings in the Vedic thought.
