A little Article on Medicine Buddha, mybe some don't know that there is a Sutra.
"Medicine Buddha is also regarded as the patron deity of healing and medicine. His Sutra, the ' Bhaiṣajya-guru-vaiḍūrya-prabhā-rāja Sutra ', is said to contain 84,000 verses on the subject of medicine and health. Medicine Buddha is typically depicted as the color of lapis lazuli or blue, which symbolizes his power to dispel disease. He is seated on a lotus flower, which represents his purity and wisdom." Etc:
