1. Eating habits
Some people think that the formation of Buddhist relics is due to monks' long-term vegetarian diet, which absorbs a lot of cellulose and minerals. After human metabolism, it is easy to form a lot of phosphate and carbonate. And finally deposited in the body in the form of crystals. The objection is that there are countless vegetarians in the world, but there are no Buddhist relics.
2. Human skeletal remains
Recrystallization of various shapes will occur when burning human bones. 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 burned and recrystallized to produce a "relic" with a crystal appearance. This possibility exists. According to the information of a Buddhist website in Taiwan Province Province: 1998, they cooperated with the Chinese Academy of Sciences in Taiwan Province Province to analyze the Buddhist relics of a monk and found that they were mainly human bones. Other scientific research has also proved the skeleton theory. In addition, teeth are also funerary objects carried by the deceased. The composition of teeth also includes many inorganic salts, among which cementum is similar to bone, so some people speculate that teeth are the source of relics.
3. Human calculus
Some people interpret this relic as a stone. Among human stones, the main components of gallstones are macromolecular organic substances (cholesterol and bilirubin) and a small amount of calcium carbonate; Kidney calculi and bladder stones are mainly composed of calcium salts (calcium oxalate and calcium phosphate), other mineral salts and uric acid. Among them, the latter is similar to the inorganic components of bones (inorganic salts containing calcium and phosphate). As the main components of stones, calcium and a small amount of metal salts will become powdery oxides at high temperature; Secondly, the opposing view is that a small number of stones in the human body will lead to unbearable severe colic, and it is impossible for patients to endure pain for a long time without delaying medical treatment; Moreover, many patients with lithiasis were cremated after death, and none of them had crystals. In addition, almost all monks who gave birth to Buddhist relics are healthy, peaceful and comfortable long-lived old people.
4. Personal effects
The shapes of relics are ever-changing, and the colors are also different; Some relics are like pearls, while others are like agates and crystals. Some are transparent, others are as shiny as diamonds. This form is not a natural product. When the monks are cremated, some will wear their personal belongings before their death, and some believers will offer offerings. Among these objects, there are many precious gems accompanied by the cremation of monks. The main component of the gems is silicon dioxide. These things will enter the cremation furnace with the remains of monks. At the high temperature of the cremator, these silica will dissolve and react with calcium carbonate in human bones to produce articles similar to bone China, glass and ceramics. This may be how the remains were formed.
5. Temperature control
It is said that relics can only be formed by cremation at a relatively low temperature. For example, in ancient times, firewood was used as fuel, and the traditional cremators used in Southeast Asian countries could produce a large number of relics. Professionals have analyzed the difference of incineration effect between pit surface cremator and grate cremator, and also pointed out that there is slag. In recent years, many monks and great virtues who left Buddhist relics have been incinerated in modern funeral homes with programmed cremators. Therefore, the formation of this relic is considered to be related to the temperature control of cremation.
