Master Xuanzang translated Liu's Sakyamuni Buddhist Sutra, and Master Yijing translated Liu's seven buddha Sakyamuni Buddhist Sutra.
The former, in ancient books, only introduces the pharmacist Liuliguang as Buddha. The latter introduces the merits and demerits of seven buddha, an oriental glazed world. This seven buddha has a deep relationship with our world.
It can be said that there is no difference. For example, what's the difference between Amitabha Buddha and pharmacist Buddha? To tell the truth, all buddhas are the same. Respectively, Amitabha Buddha is the Buddha of the western paradise, and Pharmacist Buddha is the Buddha of the oriental pure glass world. There are many buddhas in the west and many buddhas in the east.
The practice of pharmacists is mainly based on this world. The pharmacist Buddha made twelve wishes. Every big wish is to save us all. There is no distinction between good and evil. The so-called evil is just going the wrong way because you don't know the truth. If you correct it, you will not be a villain.
