What is the concept of immortality?
Immortality is a kind of person, and such people often have special skills, either with superior combat power like vampires, or with superior IQ and special skills. Such people live a more beautiful life. But there is actually another explanation for immortality. People who have always experienced death but cannot die are more miserable. They experience the pain of death all the time, which is uncomfortable just thinking about it.
If two people like this live together, they must live together. One is born to face death for the other, and one can only live and watch the other die for him over and over again.
There is a poem by Buddha that says: Linlong is not auspicious, pearls are not valuable. The monk's eyes were opened, and he could see clearly the roots of life and death. Sometimes the money is in the house, and sometimes the family is in trouble. There is a clean family tradition everywhere, and everyone can make a living.
The law of Tao says: People and I, all living beings, would rather distinguish each other's superiority and inferiority. The Dharmakaya shines brightly on me. Thoughts and bodies are similar and different. Seeing what is right was never right, hearing what is wrong is not necessarily wrong. They don't know each other's ways of going back and forth. No one in life or death can stand in your way.
So my lifelong wish is to live like a normal person, live in peace, and face life and death calmly...
