This practice is very beautiful and simple. You lie down and relax. You can either lie straight with your arms and legs close together, or in the form of a star. You relax, close your eyes and begin to concentrate on the pulse, and on the movement of the blood through your body. Now believe it or not, you can actually sense that and feel that. This practice teaches how to move from point to point through the body. Working with the tips of the fingers, toes, and nose, to become very attuned to feeling the movement of the pulse and the cycle of the pulse. Little by little, the yogi that does this practice comes to the astonishing realization that you can control it. It is possible to consciously control your pulse. This has been scientifically demonstrated many times. A yogi or a meditator can consciously slow down the pulse, and can even stop the pulse. Why is this important? This is not just a carnival act. It is important because in the very nature of the pulse we find important elements related to the consciousness, but what you specifically observe is that the experience of Samadhi occurs when the pulse is very slow.
