What has been there inside for a long time is just coming out, so let it come.
Let the mind go where it wants to go. Tell it to go, run around the world if it wants to. It may go in the past, in the future, or do anything. You sit still and watch all the thoughts. Become the observer of all these thoughts.
Today is just the first day of the course. Watch for the next two or three days, you will notice a difference.
