In the next concentric circle, particularly those mandalas which feature wrathful deities, one finds eight cremation grounds arranged in a wide band. These represent the eight aggregates of human consciousness which tie man to the phenomenal world and to the cycle of birth and rebirth.

Wrathful deities suggest the mighty struggle involved in overcoming one's alienation.
They embody all the inner afflictions which darken our thoughts, our words, and our deeds and which prohibit attainment of the Buddhist goal of full enlightenment. Traditionally, wrathful deities are understood to be aspects of benevolent principles, fearful only to those who perceive them as alien forces. When recognized as aspects of one's self and tamed by spiritual practice, they assume a purely benevolent guise. The initiate seeks to curtail his or her alienation, by accepting and enjoying all things as a seamless, interconnected field of experience. Sexual imagery can also be understood as a metaphor for enlightenment, with its qualities of satisfaction, bliss, unity and completion.
