This practice is not your individual practice carried on together with other people. We are practicing together.
That being so, you are not a great person, and never will be, no matter how much effort you expend. But you are part of a great person. And you always were.
Sometimes this person is teacher and student. Sometimes, this person is the whole network of practitioners, in all times. Sometimes the entire universe. Sometimes the tree in the garden.
When we come into the dojo, this person comes in with us. When we leave, this person leaves. Were practice to cease, this great person would fall into nothingness, leaving only bones and fragments.
But it will not.
