Question: How do you do it?

Sri Chinmoy: With your power of concentration. Suppose a thought, or a vibration, or something else is coming. Immediately, shoot an arrow and pierce it into pieces. An idea comes, somebody's name comes, or some thought comes. Immediately, just throw it out. It must not come and enter into your mind. Before it touches your mind you have to cut it into pieces. But if you already have thoughts and ideas within you, within your body, within your mind, then you have to meditate like this: be as relaxed as possible. Feel as if you were inside the ocean. Then absorb those thoughts and ideas so they do not have a separate existence. They are lost in the sea. If they are already within you, throw them into the sea. If they are coming from outside, then do not allow them to enter into you. After doing this your meditation is bound to be successful.
