Dietary habits believe that the formation of relics is due to monks' long-term vegetarian diet and their intake of a lot of cellulose and minerals. After human metabolism, it is easy to form a large number of phosphates, carbonates and so on. Finally, it appears in the form of crystals.

When human bones are burned, the recrystallization of human bones in various shapes will occur. There are many tiny bones in the human body (such as phalanges, phalanges or tiny bones in the ear canal), and a few bones are produced by recrystallization after burning.

Some people interpret the remains as stones. Gallstones are the main stones in human body.
