Iconography
Chandamaharoshana manifests as a blue-black deity with a fierce face, three eyes, and two arms. He is depicted in the kneeling achalasana posture, pressing his left knee and foot upon the forms of the Vedic gods Maheshvara, Vishnu, and Indra. Brahma is crushed under his right foot. These deities symbolize the four maras or 'obstructive demons.' Chandamaharoshana's body is adorned with golden bracelets and filigree bone ornaments. He wears a billowing green silk scarf, a loosened tiger-skin loincloth for sexual intercourse, and a garland of severed heads. His golden crown features five dry white skulls, five radiant jewels, and five silver kikinpa crowned with ornate parasols. A crescent moon and a serpent adorn his tawny upward-streaming hair, while golden victory flags appear above his ears. His red eyebrows and facial hair blaze upward, and his three bloodshot eyes gaze down at his consort.
