The different forms of the deity that appear commonly in art are also based on the more popular of the original Indian source literature such as the Samvarodaya Tantra, Abhidhana Tantra and the Vajradaka Tantra. Chakrasamvara can appear in many different forms, from simple to complex and peaceful to wrathful. This complexity makes it necessary to rely heavily on the descriptive literature in the Sanskrit and Tibetan languages to identify the various forms of the deity. Each of the different forms described in the literature are meant to emphasize different types of meditation practice that are suited to specific emotional and psychological characteristics of the tantric practitioners who take on these complicated meditation practices.
