Yog Nidra is an ancient guided meditation technique which can be practiced by anyone. During this process the student goes through different layers of brain waves, reaching the subconscious mind. It is deeply relaxing. It has been proven that when YOG NIDRA is practiced for 40 days, it changes your brain waves patterns and makes Alpha as your dominant wave. This means that you have the ability to move to a restful and meditative state sooner. It helps change Sleep patterns as well. In this video the guiding voice explores KOSHAS or different layers of body. It can be downloaded and kept for future use as well.
