Hindu / Shakta / Tantric
See main kamakhya-guwahati. This additional entry documents the specific Ambubāchī Melā: 3 days when the goddess is considered to menstruate; the sanctum is closed. Tantric sādhakas from across India + abroad gather. On the 4th morning, the sanctum opens with red cloth (said to be soaked in menstrual blood) distributed to devotees.
