Medicine Buddha is a Buddha Doctor whose function is to release living beings from outer and inner sickness by bestowing blessings upon them. By relying upon Medicine Buddha sincerely, we can be cured of heavy physical and mental disease, find release from the internal pain of the three poisons – attachment, anger and ignorance – and receive protection from many other dangers and obstacles. Moreover, by practising the Medicine Buddha Sadhana sincerely, we receive a special power of body, speech and mind, which we can then use to help others through healing actions, as presented in this Medicine Buddha Prayer.
