The food plays an important role in achieving the heights of the spirituality and for this reason special diets are recommended for religious adepts (such as eastern yogic teaching, etc) which disturb the equilibrium of biochemical reactions inside the brain which greatly helps to induce hallucinations, however the starvation is even more effective technique than special diets. It is important to note that short duration starvation will not carry the man into the “spiritual worlds” because the body will use the accumulated recourses to keep the equilibrium of brain’s biochemical reactions intact, and only long enough starvation will knock out the biochemical equilibrium when some of vital biochemical substances will be depleted.
Almost all spiritual gurus teach that in order to increase spirituality one needs to starve himself, and some spiritual gurus claim that 40 days of starvation without the food and water guarantees the entrance into the “spiritual worlds”. Long starvation disturbs the equilibrium of biochemical reactions inside the brain which result in the blockade of sensory input signals and invokes the dream simulator which carries a man into “spiritual worlds”.
Exactly the same working principle was used by American Indians. Indians had the ritual of initiation into the manhood which was mandatory for all Indian boys in order they become “true men”. The essence of the initiation ritual was the following. Indian boy must climb into the top of the mountain and he must sit there starving without food and without water day after day (which might take weeks) and he must wait until he will see the souls of the ancestors, and these souls of the ancestors must tell him his new manhood name. After the boy has met souls of the ancestors and after he has heard his new manhood name, he must climb down the mountain and tell his Indian tribe his new manhood name, and after that moment the boy becomes “true man”. However not all boys who climb on the top of the mountain meet the souls of the ancestors. Many boys starve themselves into the coma stage however the souls of the ancestors do not come to meet them. For that reason other Indians periodically climb to the mountain to check if the boy still has a consciousness or if he has fallen into the coma stage. If the boy is found in the coma stage, then he is brought back down from the mountain, revived, offered food and water and after some time the same procedure of climbing into the mountain is repeated again. The procedure is repeated the second time, the third time, etc – as many times as needed until the boy finally meets the souls of the ancestors and hears his new manhood name from these souls. Some boys who wanted to avoid this torturing ritual had cheated – after sitting several days on the top of mountain they climbed down and lied that they had met the souls of the ancestors and that these souls had told him his new manhood name. However this lie must had been kept a secret for the rest of the life, otherwise he would get death sentence for cheating in such an “important” ritual.
