Yoga Nidra is deep sleep. Many people mistakenly believe
it's twilight sleep, that stage between awake and dreaming, but it's even
deeper than that. It goes beyond the dreaming stage and into a state of
conscious deep sleep. While that sounds like an oxymoron, it's not. It's the
third of the four levels of consciousness where there are no images in the mind.
Mental images live in the domain of a waking state, the first level or the
dreaming state, the second level. It is a deep meditation right before the last
level, the turiya, higher consciousness.
