Freedom over birth and death is freedom to come and go
Those who investigate Chan can become masters over their own birth and death. They can come and go freely without any restriction. As it is said,
My destiny is determined by me, not by heaven.
Even Old Man Yama will no longer have control over us! Why not? We will have transcended the Three Realms. What does freedom to come and go involve? It refers to freedom to be born and to die. If we want to live, we can live. If we want to die, we can die. The choice will be ours, as we wish. Please take note, however, that this kind of death does not mean committing suicide. This freedom allows us to relate to our physical body as we would our house. If we want to go out and travel, we will be free to go wherever we want. If we wish, we can have a hundred million transformation bodies to teach sentient beings throughout empty space and the Dharma Realm. If we do not wish to travel, we can stay in the house and no one will disturb us.
We should know that everything in empty space and in the Dharma Realm is included within the Dharma-body. Nothing can go outside the Dharma-body. All of you have gone to a lot of trouble to attend this Chan session, and to work non-stop day and night. You are doing this because you hope to gain freedom and security over birth and death. You want to control your own life and to be your own master. Being able to do that is truly the state of freedom over birth and death. In investigating Chan, you need to reach the state of not knowing that there is sky above, earth below, and people in between. You need to become one with empty space. Then there is some hope for enlightenment. Right now, walking and sitting, sitting and walking provide the key that will open our wisdom.
