Yoga Nidra is a yoga practice used to access and experience a deeper state of consciousness where you are fully aware but deeply relaxed. We work through physical tensions first and then learn to observe and let go of thoughts, becoming a witness to the mental fluctuations or thought patterns in order that we can learn to step back, witness and observe them and in doing so practice letting go of thoughts. In this deeper state of presence, we can allow thought to come and go and observe the restful peaceful state of consciousness from which they arise. The practice is often said to be equivalent to a few hours sleep where one can emerge rested, restored and relaxed.
