Body Mandalas, also referred to as 'internal body mandalas, are based on the physical human body, the nervous system, veins, arteries, spine and principal joints of the body. All of these grouped physical parts of the body are visualized (imagined) to be major and minor deities. Body Mandala theory and practice is found with many of the religious and spiritual movements in Asia such as the Shaiva, Shakta, Tantric Buddhism, Bon and Taoist religions.
