Sit comfortably and try to maintain the natural curves of your spine. If you need to, sit against a wall, or even in a chair (if you sit in a chair, ensure your feet are grounded). If sitting comfortably is not an option, please create a comfortable laying down position.
TO YOGA NIDRA
DO create a comfortable laying down position with pillows, blankets and an eye pillow (or towel to cover your eyes).
