A visual aspect of Tantric Buddhism is the common representation of wrathful deities, often depicted with angry faces, circles of flame, or with the skulls of the dead. These images represent the "Protectors" (Skt. dharmapala) and their fearsome bearing belies their true compassionate nature. Actually, their wrath represents their dedication to the protection of the dharma teaching as well as to the protection of the specific tantric practices to prevent corruption or disruption of the practice. They are most importantly used as wrathful psychological aspects that can be used to conquer the negative attitudes of the practitioner.
