Who am I? There are different understandings.

Because of different schools of thought, the explanation of this problem is also different. Buddhism believes that I have three things, namely, past life, present life and future, which interact and complement each other; Taoism believes that this "I" is just a tool to soar to immortality; Christianity believes that "I" is a particle created by God in this painful world that needs constant repentance. In fact, you can think so, which means that you are already confused. We won't explore the reasons, but I believe that all theories are founded by people, and the Bible is not faxed from heaven. The key is to see if you can see through it yourself. I wish you success.
