In plain words
O wise one, when the mind assumes the form of pure consciousness and transcends the surging waves of mental modifications, the direct experience of bliss that arises is known as the deep-sleep-in-waking state.
Close to the Sanskrit
Minds having the form of consciousness, gone by expanses of intellect-modifications, the experience of bliss, O learned one—deep sleep-waking is thus declared.
