Yoga Nidra is an ancient sleep based meditation that takes you below the level of the mind and connects you with your true self. It uses the biological process of sleep to effect changes in your body  that improves your overall health and wellbeing  including decreasing cortisol, the stress hormone and increases endorphins which has the effect improving your mood and sense of peace. Once you drop below the level of the mind and thoughts you enter into a place of profound stillness and peace where true cellular healing occurs. In this place of stillness you unlock the power of the subconscious, place an intention which will help to erase self-destructive  habits and behavior patterns. It is a practice of awakening to your true self. Replacing old patterns that no longer serve you  with new more life affirming ones.
