Yoga Nidra is a practice of deep relaxation and inner awareness adapted from traditional tantric practices by Swami Satyananda Saraswati for the needs of modern people. It is outlined in detail in both "Yoga Nidra"
and "Meditations from the Tantras". Research shows that this practice takes us into a deeper state of relaxation than we usually experience, even when we are asleep. Ordinarily, when we relax we continue to experience some level of tension within our minds and bodies. Often our attempts to relax are counter-productive such as sitting in front of the tv or using alcohol or either prescription or non-prescription drugs. True deep relaxation brings about healing within our bodies and within the deeper levels of our psyches. It helps us to enter into a state of unity within.
The practice has four primary components. First is "sankalpa" or "resolution. The sankalpa is a resolution which is formulated on an individual basis and planted in the deep levels of the subconscious mind. It is a powerful way of changing habits or achieving goals in life. Second is the rotation of awareness through the body. In this stage we become aware of sensations throughout the body and relax it completely. Third is the experience of "pairs of opposites": hot and cold, heaviness and lightness, etc. leading to a deeper release of tensions. Fourth is the practice of visualization which can take various forms. Best, I believe, is spontaneous visualization where we allow the mind to express itself as we witness objectively.
Yoga Nidra has tremendous healing power. As a therapist I have used it to help people with anxiety and depression, for pain management and recovering from both physical and psychological trauma. It has also been used effectively in helping to treat cancer. Most of all, when you practice and enter into that state of total relaxation, it feels great!
Yoga Nidra is best practiced with guidance, with a teacher to give guided instructions or with a recording. A live teacher is best though.
