Yoga Nidra, also known as yogic sleep guides you into a state of consciousness between wakefulness and sleeping. The "going-to-sleep" stage is typically induced by a guided meditation known as Yoga Nidra. The experience guides you into a deep brain-wave state—one that can't be reached through conventional sleep. Each time you practice yoga Nidra, you're stilling the waves of the mind through conscious entry into the sleep state, relieving stress and anxiety, aiding in relaxation.
