Heruka Chakrasamvara, also known as the Wheel of Perfect Bliss, is a tantric meditational deity (Yidam) of three Highest Yoga Tantra (Anuttara) of Vajrayana Buddhism. He can appear in several dozen different forms, from simple to complex, and peaceful to wrathful.

Chakrasamvara, along with Hevajra and Vajrayogini, are the three main meditational Yidam practices of the Kagyu Lineage.
