This meditation also traditionally known as yoga-nidra is often used to help people get much needed deep sleep. It is also used to reconnect with the deepest part of our being. The meditation uses different techniques from the quick body scan rotation to listening to sounds, paying special attention to the sense of touch and counting the breath backwards to change the state of the brain. During regular meditation practice you may experience Alpha brain waves which are the relaxed, focus state. With Yoga-nidra you can also experience Theta waves which are associated with dreaming and even Delta waves which are associated with deep sleep. The practitioner who stays awake during the meditation may experience both dreams and deep sleep while still awake, like an observer. Some people call that transcendence as you transcend the mind and experience a completely different state. The result is an incredibly refreshing state and the feeling of being reconnected to one’s core being. Or you may just fall asleep and for some that is already a tremendous value in itself.
For this practice it is important to be as comfortable as possible and to lay down on your back. You can do it on a yoga mat or on your bed without a pillow. Having a light blanket to cover yourself is a good idea as your body may get cold as you get into complete relaxation.
