Ashta Dikpalakas are the eight gods ruling the eight quarters or the eight zones of the universe. They are
Indra (East),
Agni (Southeast),
Yama (South), Niruthi (Southwest), Varuna (West),
Kubera (North) and Eesana (Northeast).
According to Hinduism, each direction is assigned to a particular god as chief guardian ensuring orderliness of the universe and the protection of its occupants. Vaastu Shastra is based on these eight directions.
