The spot on the monk's head is actually called a ring scar in the temple. In fact, it is a scar burned with incense, not painted. Moreover, not all monks are qualified to have a scar, even if they can have a scar, how many can be different. The better the monk's performance, the monk who is connected with the Buddha at Huigen is entitled to get the scar.
Therefore, it is not easy for monks to scar. If he is outstanding in the temple, a senior monk will help the young monk get a scar. In the temple, everything is empty, that is to say, if you can't achieve anything, you will have a greater fate with Buddha and understand Buddhism faster. This is a talented monk, and naturally you can be the leader of the young monk.
So a little bit on the monk's head is actually equivalent to giving the monk a medal. But it is definitely inconvenient to wear a sign in the temple, and there are so many monks in the temple. In order to confirm their identity more quickly and accurately, as long as they point dots on their heads, they will know each other's identity as long as they see the dots on their heads, so it is not easy for monks to get nine dots.
If you stay in the temple for a long time, you really can't achieve anything, and there are no commandments to limit yourself, then you are qualified to get nine scars on your head. Therefore, this ring scar is mainly to distinguish identity, and it cannot be removed after it is formed. It is also very painful to quit the scar in the process of ironing, so when accepting the reward of quitting the scar, it is actually a practice.
After all, burn scars with real incense. This process is very painful, and the monks who can bear it are also very patient.
