Sadyojata

Panchanana Shiva

In some temples, Shiva is shown with five faces. Each of the faces has a name and represents a specific aspect. These five faces are:-
Isana
Tatapurusha
Aghora
Vamadeva
Sadyojata.

Isana faces North-east and represents the Ishwara aspect of Shiva known as Sadashiva or the Eternal Shiva.

Tatpurusha faces the east and represents the deluded purusha or ego aspect of Shiva.

Aghora faces south and represents the destructive and regenerative aspect of Shiva, that like fire, first devours life and then prepares the ground for its renewal.

Vamadeva faces north and represents the healer and preserver aspect of Shiva.

Sadyojata faces west and represents the creative power of Shiva.

So, in Hinduism, Sadyojata is the name of the creation-enfolding aspect of the god Shiva, one of five aspects of the universe he embodies, and one of the five face manifestations of Shiva. On a five faced lingum, Sadyojata is on the back. It represents Shiva manifest in all of nature. (Earth)
