Yoga Nidra

Yoga Nidra, meaning yoga sleep, is an ancient technique derived from the tantras where the practitioner is guided to a deep state of conscious relaxation. It is a systematic method of moving awareness inwards, away from external experiences, to induce complete physical, mental, and emotional relaxation.
Though the practitioner may look like they are sleeping, their consciousness is working at a deeper level of awareness, which can help improve memory and increase knowledge and creativity.
