Why does it work?
It is similar to hypnosis because you are in a suggestive state Except in Yoga Nidra, the central nervous system actually awakens the brain completely. During Yoga Nidra, the brain receives a higher quality of stimuli and a different type of knowledge. This kind of awareness experience is completely different from any other time. This is why when we move through the physical relaxation... to the mental relaxation of each body part... releasing and letting go of any tension or resistance... You are able to dive deeper and feel the power of actually letting go much deeper than on just a physical level. And in hypnosis the brain is isolated from the sensory channels and the knowledge you receive is limited.
I recorded this very quick... short video... Because sometimes, the power of hearing it makes it all that much more real!
