Explanation of Goddess Kali's form

Kali is the personification of that aspect of the Divine Mother that compassionately destroys the ego.

Her dishevelled hair hints at unrestrained blood lust and alternatively the metaphysical mystery of death that encircles life. Her three eyes represent omniscience, her voluptuous breasts both sexual lust and nurturance. Her nakedness simultaneously represents carnality and purity. Her necklace of severed heads and girdle of severed arms signifies her killing rage but are also tantric metaphors for creative power and severance from the bonds of karma and accumulated deeds.
