Buddhism makes mind its foundation and no-gate its gate.
Now, how do you pass through this no-gate?
It is said that things coming in through the gate can never be your own treasures. What is gained from external circumstances will perish in the end.
However, such a saying is already raising waves when there is no wind. It is cutting unblemished skin.
