5. Wrathful Look
An enigmatic aspect of Tibetan Buddhist iconography is the presence of "ferocious", "terrifying" forms known as the wrathful deities. Though these hideous, hair-raising images seem contradictory to Buddhist ideals, they are not personifications of evil or demonic forces at all.
Rather, the wrathful deities are benevolent gods who symbolize the tremendous effort it takes to vanquish evil, the violence that is a fundamental reality of the cosmos and the human mind and protect the faithful by instilling terror in evil spirits.
In Sanskrit, the wrathful deities are known as dharmapalas, which means "defender of the dharma." In Tibetan, they are drag-gshed, meaning "cruel, wrathful hangman."
Images of the wrathful deities are kept in the homes and temples of Tibetan Buddhists to protect them against evil influences and remind them to destroy passion and evil in themselves.
A typical wrathful expression: the mouth is contorted to an angry smile, from its corners protrude long fangs or the upper teeth gnaw the lower lip. The protruding, bloodshot eyes have an angry and staring expression and usually a third eye is visible in the middle of the forehead.
