In Vedic literature we come across a divine hawk named
Shyena. The bird is a divine messenger and is identified with Agni. Shyena
ascended to the heaven and brought Soma or nectar of immortality to earth. Thus,
Soma is also known as Shyenabhrita.
The soma that was brought to earth from heaven was used for rejuvenation
and revitalization of all things on earth.
The common type of altar that is built for Vedic yajnas is
in the form of Shyena with outstretched wings.
