Popularly known as medicine or healing Buddha, the common name "Bhaisajyaguru" is given to anyone who is a master of Ayurveda. Bhaisajyaguru resides in the central golden abode as fifty retinues surround him. He holds a medicinal plant in his right hand turning upright. The left hand lies on the lap with a bowl full of medicinal plants and fruits on it.
There are fifty deities making three circumambulations around the chief deity. The first circle contains eight deities. The second circle contains fifteen deities, the third circle contains twenty-five. On the gates are guardians of the four cardinal directions. This mandala is listed in the book The Mandalas of Tibet.
In Tibet the use of a painted mandala for practice of Buddhist tantric Sadhanas became very popular. The classical Indian Tantra practices are divided into four major Principle classes. The classes are just like different stages where the practitioner visualizes different mandalas of tutelary deities. This particular mandala of the Bhaisajyaguru belongs to the class of Kriya tantras, which are initial tantric practices of Buddhism.
Mandalas are a special subject of Buddhist paintings having a large number of canons dedicated to them. The artist needs to go through the texts while drawing his mandala in order to make it appropriate for meditational uses.
