A Yoga Nidra technique that can be used at any time as a centering and relaxation exercise.
Practice using the audio and then shift to doing it independently so that it can be available to you at any time.
If you practice Yoga Nidra regularly, the muscle memory that you have from using the technique in the Nidra will kick in and over time you will access a deeper level of relaxation than from doing a stand alone exercise.
