The inner Dakini is awaken trough the practice of Chandali Yoga (or Tummo)
As a breathing exercise, Chandali yoga is a part of tantric meditation cycles for yogic heat, developed around the concept of the female deity.
In the practice of chandali, the visualization is primarily used to focus body awareness in the subnavel area - the Womb space in women or the Hara in men.
Miranda Shaw clarifies: “Kuṇḍalinī-yoga offered a range of techniques to harness the powerful psycho-physical energy coursing through the body... Most people simply allow the energy to churn in a cauldron of chaotic thoughts and emotions or dissipate the energy in a superficial pursuit of pleasure, but a yogi or yogini consciously accumulates and then directs it for specified purposes. This energy generates warmth as it accumulates and becomes an inner fire or inner heat (candālī) that [potentially] burns away the dross of ignorance and ego-clinging.” The psychic heat Drod is produced by the space particles and the heat manifested from the friction of the wind element. This is another fundamental element as it supports and gives power to the consciousness, like the power of the fire that can launch rockets to space.
The power is called medrod or 'digestion fire' in medicine and Tummo in yoga tantra.
The psychic fire increases the wisdom, burns the ignorant mind of the brain and gives realization and liberation from the darkness of unawareness. That is why yoga describes Tummo as the fierce fire which ignites from below navel, pierces the chakras one by one and reaches the sky of the crown chakra. “The tummo burning arrow married with the celestial bride leads to enjoy the life of transformation of samsara. They give birth to the son of awareness from the blissful garden of Vajrayogini.”
