Practice is to remove the habit of practice. Then realize that freedom is already here. What is here right now needs no practice. Just see what the impediments are. What is the wall? The wall is imagining that you are not free. When you make an effort to be free, you accept the concept that you are not free, so you start from there. If you get rid of this concept that "I am not free," what will happen? This imagination is your own creation.
