Tryambaka Deva, three-eyed Lord, Shiva. The sun is said to be his right eye, the moon the left eye while fire is his third eye. While his other two eyes indicate his activity in the physical world, his third eye in the center of his forehead looks beyond the obvious.

Tryambaka Deva, three-eyed Lord, Shiva. The sun is said to be his right eye, the moon the left eye while fire is his third eye. While his other two eyes indicate his activity in the physical world, his third eye in the center of his forehead looks beyond the obvious. ‪It stands for spiritual knowledge and power, and is thus called the eye of wisdom or knowledge. Like fire, the powerful gaze of Shiva's third eye can search evil from anywhere and annihilate it completely. This is the reason why evil-doers fear his third eye.
