Maa Dhumavati Maa  (Sanskrit: 
धूमावती, 
Dhūmāvatī, literally "the smoky one") is one of the Mahavidyas, a group of ten Tantrik goddesses. Dhumavati represents the fearsome aspect of Devi, the Hindu
 Divine Mother. She is often portrayed as an old, ugly widow, and is 
associated with things considered inauspicious and unattractive in 
Hinduism, such as the crow and the 
Chaturmas period. The goddess is often depicted on a horseless chariot or riding a crow, usually in a cremation ground.
Dhumavati is said to manifest herself at the time of cosmic dissolution (pralaya)
 and is "the Void" that exists before creation and after dissolution. 
While Dhumavati is generally associated with only inauspicious 
qualities, her thousand-name hymn relates her positive aspects as well 
as her negative ones. She is often called tender-hearted and a bestower 
of boons. Dhumavati is described as a great teacher, one who reveals 
ultimate knowledge of the universe, which is beyond the illusory 
divisions, like auspicious and inauspicious. Her ugly form teaches the 
devotee to look beyond the superficial, to look inwards and seek the 
inner truths of life.
