Sensory Deprivation Tank And Induced Samadhi by John LeKay

Sensory Deprivation Tank And Induced Samadhi 
By John LeKay 

[John LeKay is a professional artist and an accomplished Non-dualist. He arrived at the realization of Oneness following several methods of meditation and yogic practices like 40 days rigorous starvation and contemplation in Desensitization Chamber.  He, however, discovered on realization that the induced Samadhi, the effect of these practices, was not very different from deep sleep state and the meditation he did was not what one would really call the effortless Non-dual meditation.  Non-dual understanding, he says, is a transformation of the mind from its habitual thinking of being a separate entity. An inexpressible ‘Life’ lives by itself once such an understanding dawns. John lives in New York with his family and hopes to publish a book soon spelling out the diverse experiments he carried out and his findings. He also edits a well-structured online Journal reflecting various facets of Non-dualism. He can be reached at 

I am grateful to John for contributing this Post on the techniques of desensitization of the senses and induced Samadhi and their usefulness to a seeker – ramesam.]

Neurologist Dr. Oliver Sacks in his latest Book "Hallucinations" (Alfred A. Knopf, 2012, pp: 323 ISBN 978-0-307-40217-2) writes about "sensory deprivation" research studies carried out during the decades of the 50s and 60s in the 2nd Chapter, p: 34-46. Almost all the research carried out showed that the subjects suffered from hallucinations.

Dr. Sacks mentions that a 1969 book edited by John Zubek entitled "Sensory Deprivation: Fifteen Years of Research" listed 1300 references.  However, the scientific interest in the subject later petered out   A 1984 paper pointed out that the hallucinations derived from sensory deprived conditions "can be magnified sometimes to madness, especially when combined with social isolation, sleep deprivation, hunger, thirst, torture, or the threat of death."  More recently, Alvaro Pascual-Leone and his colleagues reported on their work on pure visual deprivation. Ten of the 13 subjects experienced hallucinations during the first hours of blindfolding, but always by the second day, whether their eyes remained open or shut behind the blindfolds. -- ramesam.

I am interested in John's experiences with integrating his "shadow" unconscious "samskaras". Not many discuss these inevitable discoveries.

I've wondered from time to time if an isolation chamber of some sort would force one into presence. Once you take away all senses (as much as possible), then you are left alone with your thoughts. It would then seem easier to allow them to be as they are enough to realize that they are not you, thereby disidentifying with thought completely (eventually). It sounds like that's what can happen, but that it's not a permanent solution.

I wonder about things like this, and virtual reality immersion (complete with goggles and suits) as a means of shortening the journey for beginning seekers. It seems important to me to create new ways of getting people to break their identity with (or at least question) what they consider to be the real world. It would seem that giving people a taste early on in the search would help end it faster.

In reply to the Comments by Chris, John answered as follows:

"Hi Chris,
yes, like you, feel this is the crucial and one of the keys to liberation, otherwise its like only looking at the tip of an iceberg, seeing that melt away and thinking that's it, but not addressing the mountain of ice under the water.

Tilak from India has the following questions:

"It is not clear to me as to how one can live without oxygen when once the tank is closed for such a long time. Also, it is unclear whether part of the experiences the author had undergone is due to biochemical action of saline water in which he floats. I wonder whether one and all who can try experimenting in this gadget will undergo the same experiences as the author had, or does it require some sort of preconditioning the mind by practicing meditation?"

John's detailed reply to these questions is posted at the main Blog Post itself.
