Mundamala

[2] Other Mahavidyas like Tara, Chhinnamasta, Bhairavi, Dhumavati and Matangi are depicted or at least described wearing mundamalas; the goddess may also hold a severed head or skull (kapala) in her hand.

[13] Other fierce forms of Shiva wearing the mundamalas include Virabhadra, Gajasurasamhara ("Slayer of the Elephant demon") and the eight-armed Aghoramurti.

[14][15][16] The fifty or fifty-two heads or skulls in the mundamala are described to symbolize the letters of the Sanskrit alphabet in Kali's iconography, thus signifying the wearer Kali as sabda Brahman, Ultimate Reality recognized as Sound and the primal sound of the sacred syllable Om.

[17] Another interpretation links the mundamala symbolizing the heads of foes and demons slain by the wearer goddess in battle.

[10] In Tibetan art, various wrathful deities, including the dharmapalas, wear the mundamala, a five-skull crown and human or animal skins.

[27] In Chakrasamvara's iconography, it symbolizes the "abandonment of phenomenal appearances" as well as his union with his consort Vajravarahi (when depicted with him).
