Ambubachi Mela is a four-day fair to mark the annual menstruation of the goddess at Kamakhya temple in Guwahati.

Kamakhya is one of 51 shaktipeeths or seat of Shakti followers, each representing a body part of the Sati, Lord Shiva's companion. The temple's sanctum sanctorum houses the yoni - female genital - symbolised by a rock.

The ritualistic fair celebrating the goddess' period is one of the reasons why the taboo associated with menstruation is less in Assam compared with other parts of India. The attainment of womanhood of girls in Assam is celebrated with a ritual called 'Tuloni Biya', meaning small wedding. Ambubachi Mela is also an occasion to promote awareness on menstrual hygiene.
