This voice-only yoga nidra will walk you down into lower and slower brainwave states into a state of "body-asleep, mind-awake." This state of yoga nidra has similar benefits to the stages of deep sleep, but you achieve that state of deep rest and healing in a much shorter time frame with these types of guided meditations. You can think of yoga nidra as a way to reset your nervous system: shutting the whole thing down and rebooting.
