Donna Halper: How does one discipline one's life? What does one have to do?

Sri Chinmoy: He has to be very careful in every way, beginning with the mind. He has to feel that his mind is a room that has a few doors and windows which will let the whole world inside. The seeker has to close the doors and windows and stand at a particular door. Then he must allow inside only the thoughts and ideas that are going to help him in his spiritual life. Purity, peace, harmony, and so on — these are his friends. So he will allow them to enter into his mind-room and he will converse only with them. This is how the individual can practise.
