Yoga Nidra is the "yoga of the sleep". It's good to know that there is also a type of yoga that needs no physical movements, right? Jokes aside, it is a wonderful tool to relax and restore your whole system. It is also good when you need to slow down from the day. You will feel rejuvenated, light and clear. Let go of your body, listen to my voice and let the source speak with you through you. Practice as many times as you wish. I wish you a restorative and loving practice.
