Kinkara are special Dharma Protectors for practitioners of Heruka and Vajrayogini. They are emanations of Heruka and Vajrayogini who emanate as skeletons. This appearance of being devoid of flesh symbolizes that enlightened beings are completely free from self-cherishing.

For more information on Vajrayogini practice, see the book Guide to Dakini Land, and for more information on Heruka practice, see the book Essence of Vajrayana.
