In Sanskrit, the Guru of Medicine (Skt.: Bhaishajyaguru) is known by the name Vaidurya Prabha Raja, the King of Lapis Lazuli (or sapphire) Light. Dark blue in colour with one face and two hands he holds in the right, in the gesture of supreme generosity, a myrobalan plant (Latin: terminalia chebula. Skt.: haritaki). The left hand is placed in the lap in the gesture of meditation supporting the black begging bowl of a monk - filled with nectar. Adorned with the patchwork robes of a fully ordained monk and the left arm covered, appearing in the nirmanakaya aspect of a buddha he is seated in vajra posture above a lotus and lion supported tiered throne. Standing to the left is the bodhisattva Suryabhaskara, orange in colour, the left hand holding a lotus marked with a sun and on the right side is Chandrabhaskara, white, the right hand holding a lotus marked with a moon.

Above Suryabhaskara is the mother of wisdom Prajnaparamita with four hands, orange, seated, flanked by two standing bodhisattvas. To the other side above Chandrabhaskara is the buddha Shakyamuni flanked by two standing bodhisattvas. Vertically along each side are three buddhas each flanked by two bodhisattvas. These six are referred to as the brothers of Vaidurya Prabha and all together they are known as the 'Seven Buddhas of Medicine.'

Along side the lion throne are the Four Direction Guardians, Vaisravana, etc. Below that are two horizontal rows of figures. The upper row contains the ten Gods of the Directions each riding on a different animal mount. At the far right side are two additional figures mounted on chariots. The 12 Yaksha Generals specific to the Sutra of Medicine Buddha comprise the lower row.

At the top are rows of smaller buddhas, all in the same appearance, representing the set of 53 Buddhas along with the Seven Lord Buddhas of the Past with one extra making a total of 61 buddhas. The form and practice of Medicine Buddha is derived from the Bhaishajyaguru Sutra taught by Lord Shakyamuni. In the Vajrayana Tradition this sutra is classified as a Kriya Tantra. Common to all schools of Tibetan Buddhism Medicine Buddha is particularly important to the Tibetan medical traditions.
