Duration: 21 minutes
Sit and be as relaxed as possible. Do not put your weight on the spinal cord. You can support yourself with your hands.
Visualize energy leaving your body through your eyes, nose, tongue, ears and other sense organs. You are becoming completely empty.
Visualize that you have now become empty. Feel that you have become empty. Whatever you thought of as you is already gone. You are completely empty.
When you feel you are completely empty, stop visualizing.
Be a witness. Witness your thoughts and the gap between your thoughts. Do not create any thought or destroy any thought. Just witness the thoughts and the gaps flowing in you.
