In the Medicine Buddha practice there is the main Medicine Buddha who is shown here the color of lapis and holding the arura plant in the offering gesture in his right hand and a bowl of medicine buddha in his left. He is directly under the Akshobhya Wisdom Buddha whose family he belongs to.

The Medicine Buddha practice (which is given in the Practice section of this website) is used for sending mental and physical health and well being to all beings or to a particular ill person.  

The seven attendant Buddha are: The excellent name, the freedom from sorrow, the proclamation of Dharma, King of clear Knowing, King of Melodious Sound, and the Shakyamuni Buddha himself.
