Inhibitory gnosis is a form of deep meditation into a trance state of mind. This type of gnosis uses slow and regular breathing techniques, absent thought processes, progressive muscular relaxation, self-induction and self-hypnosis techniques.
Means employed may also include fasting, sleeplessness, sensory deprivation and hypnotic or trance-inducing drugs.
