The Non-Self Elements
The self is made of non-self elements; therefore, understanding ourselves is our practice. Our father is a non-self element. We say our father is not us, but without our father, we cannot exist. So, he is fully present in our body and in our mind. He is us. Thus, if you understand yourself; your whole self, you understand that you are your father, that he is not outside of you.
There are so many other non-self elements that you can touch and recognize within yourself- your ancestors, the earth, the sun, water, air, all the food you eat, and much more. It may seem like these things are separate from you, but without them, you could not live.
Know Yourself First
Suppose two warring parties want to negotiate, and both sides do not know enough about themselves. You have to really know yourself, your country, your party, your situation, in order to understand the other’s party, the other’s nation, the other’s people. Self and others are not two separate things because the suffering, hope, and anger of both sides are very much the same.
