A dhuni is (according to the Indian religions such as Hinduism, Buddhism, Jainism, etc.) a sacred site represented as a cleft in the ground. This cleft is emblematic of the yoni or female vulva and generative organ. A dhuni therefore represents a site of worship dedicated to Shakti.
The dhuni (or dhunga) is also a term used in Indian cuisine to describe the process of cooking food by placing smoking charcoal into the finished dish.
Sitting by the dhuni is believed to "purify one's vibrations" and to have beneficial impact on physical and mental health.[1]
