The self is made of 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, 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.
– Thich Nhat Hanh
