In Tantrik literature, Ḍākinī the goddess is usually associated with the saptadhatus (the seven primary constituent elements of the human body) or the six chakras. The Kubjikāmata Tantra for instance enumerates seven yogini goddesses (Kusumamālinī, Yakṣiṇī, Śaṅkhinī, Kākinī, Lākinī, Rākinī, and Ḍākinī) to whom the ritual practitioner symbolically offers his semen, bones, marrow, fat, flesh, blood and skin, respectively. A nearly identical listing of goddesses can be found in a later text belonging to the same tradition, the Śrīmatottara Tantra.
Dakini is an energetic and sacred shakti. Along with Bharat, this shakti is given special importance in the culture of China and Tibet. In many ancient texts, she has been described as the form of Mahakali and in many texts she has been described as the sevikas of Mahakali.
Some of their forms are also associated with Maa Chhinnamastika. It has been told in Markandeya Purana that Dakinis are very powerful and move in space. Dakini Sadhna is very difficult. The only person to climb Mount Kailash in Kali Yuga was Milarepa.
Milarepa was a great sadhak and yogi of Tibet. He had done Dakini Sadhana only after which he was able to climb Mount Kailash. Dakinis are also called the goddesses of Samsan. The form of Dakini is very fierce and she takes tamasic bhog. She dances on the dead body.
When a sadhak reaches the Muladhara chakra while doing sadhna, Then Dakini appears and scares him. If the sadhak does not deviate from his sadhna, then she tries to attract him towards herself by becoming a rupvati.
If the Dakini is pleased with you, she will give you every precious thing in the world and if she becomes angry, she will destroy you. That’s why not everyone should do Dakini Sadhana.
