The medicine Buddha, the Teacher of Medicine and the king of Lapis Lazuli Light (Bhaishajyaguru, Sangye Menla, Vaidurya).

His radiant body is azure blue. His left hand is in the meditation mudra and holds a begging bowl full of long life nectar in his lap. As a sign that he gives protection from illness, his right hand is outstretched in the gesture of giving and holds the "great medicine", the myrobalan plant (a-ru-ra).

Following verses is reprint from Chagmed Rinpoche's Hymn in Praise of the Medicinal Buddha

Namo Maha Beshajeya

Honor to the Great Medicinal Buddha!
Whoever due to wrong ideas and attitudes
Is bound to fall into states of suffering
If he even hears the sound of your sacred name,
He will not be reborn in sorrow
And will reach the state of immaculate Purity.
Medicine Buddha Mantra

" Om Namo Bhagavate Beshajeya Guru Bedurya Prabha
Rajaya Tathagataya Arahate Samayak Sam Buddhaya
Tadyataya Arahate Samayak Sam Buddhaya Tadyatha
Om Beshajey Beshajeya Maha Beshajeya Beshajeya
Rajaya Samungate Savaha "
