It allows me to "empty my cup," so there is room for something new.
It allows me to be "teachable." I can learn something.
Then I do not have to reinforce the things I thought I was or thought I knew with my new experience. I can be free to see and experience things way they are.
It is the most powerful teaching and tool that I was ever given.
Try it sometime. You will be amazed at what you discover.
