The Easy Way
Just before going to bed at night concentrate your attention on the Spiritual Eye, that place between the eyebrows. Chant HU or God inwardly and silently.
Hold your attention on a black screen in the inner vision, and keep it free of any pictures if at all possible. If you need a substitute for mental pictures flashing up unwantedly, put the image of the Living ECK Master in place of them.
After a few minutes of this, you may hear a faint clicking sound in one ear or the sound of a cork popping. You will suddenly find yourself outside the physical body, looking back at it in the room. Now you are ready for a short journey in the other worlds.
There is nothing to fear, for no harm can come to you while outside the body. Although you may not know it, the Mahanta will be standing by to keep watch over your progress. After a while the Soul body will return and slide gently into the physical self with hardly more than a very light jolt.
If this is not successful the first time, try it again, for the technique works. It has worked for others.
