Sadyojata (“quickly birthing”), the controlling Lord of Brahma, is the aspect of Siva that wields the power of creation. His direction is west, He is related to the sphere of earth (prithivi mandala) and His Panchakshara Mantra syllable is Na. The Agamas describe Him as white in color, in the likeness of a boy with a charming face, besmeared with sandalwood paste, adorned with white flowers. One hand displays the boon-granting varada mudra and another the fear-not abhaya mudra. He is Siva manifest in all of nature; the causer of birth.
The drum symbolizes the power of creation.
