Please don't tl;dr or skim through, I bet you'll find this topic rather interesting!
Now I know what many of you are thinking right now. You're thinking about defending your spiritual views and denounce
any involvement of placebo. Why? Because most of you have had a very negative image of the placebo assembled for you by the culture in which we live. Placebo is mostly associated with double-checking in the scientific field and it seems to have a mild association with deceit, right? But hold up! Let's try and look at this from an entirely different perspective!
"It's just a placebo effect!" someone would say for one reason or the other and it would immediately makes us feel stupid. But why? Has no one ever thought that a placebo is actually a perfect demonstration of the power of the mind? A placebo effect is merely an emotional stimulation of the mind that changes its chemical structure because 'you allowed it' or 'you believed it' or even better 'you knew it'.
When we talk about placebo effects we can't seem to placebo someone into seing the external world as being changed because of the intentness of the external information towards the brain, but we can seem to influence how the person feels about and relates to already acquired information.
When lucid dreaming, you won't be able to preform miraculous changes in your dream-world (such as flying or blowing shit up) if you don't KNOW that it's going to happen WHEN you want it to happen. This, believe it or not, is also a form of placebo, albeit completely self-induced. The word placebo is derived from the latin phrase "I shall please', which is very suiting for the points I'm about to make.
Now put aside what meaning you've formally attached to the word placebo and try to see it only as a way of influencing the brain via emotional discharges. It becomes quite a different thing then doesn't it? I have a hypothesis that meditation and ritualistic practise has a deep connection with placebo and nocebo as well. Not that you're in any way "tricking" yourself into altered states of consciousness but instead, you're actually "letting yourself" enter these states by stimulating certain emotions through various means with specfic intensions.
So far, I have listed 7 types of emotional stimuli:
Visual - mainly consists of symbols. The symbols may me physical (such as a pendant or a yantra during rituals) or hallucinogenic in their nature.
Cognitive - dance, ritualised movement (such as to cross oneself), poses.
Audial - music, sounds, chanting
Odorous - smells such as specific incense that bears you specific sentiment
Gustatory - mainly associated with taste and expected/actual effect, ritualised consumption of potions, drugs, food, etc.
Authoritative - this one is very interesting indeed. It combines a lot of the other listed stimuli, but is usually perceived as a higher figure. Wether a priest, a shaman, a scientist, the sun or the starts in the sky, they're all part of the authoritative kind of emotional stimuli. Arguably the most potent.
The brain does not discriminate wether something is completely true or not, unless you have specific doubts and suspicions beforehand. Otherwise, it will react emotionally to anything, if you allow it to.
Intensions play a huge role in any rituals and meditation. With intension you aim all the emotional power you accumulate through the previously mentioned types into a single, specific point in your brain. And doing it often enough or well enough will trigger a reaction from your brain, that being of changes in the chemical balances.
I have read in a science paper about the study of the 'happiest man alive'. This man is a buddhist monk with high achievements in the meditative arts. Apparently, his brain's dopamine and seratonin output is 3 times larger than that of an average person. This article only confirmed my suspicions.
Concerning the placement of deities in all of this, it's quite simple. Some traditions of meditative/ritualistic practise are more inclined towards one or another type of emotional stimuli. This is due to cultural background and history. Some traditions are morei inclined towards authoritative and visual stimuli such as hinduism. Other, such as buddhism, are more inclined towards cognitive and audial types of emotional stimuli. Those who are strongly inclined specifically towards visual and authoritative stimuli often create deities and gods.
This is because their mind is already inclined towards turning everything into a symbol, but unlike inanimate symbols theirs also gain the traits of with willpower and authority, resulting in the manifestation of gods, which are merely manifestations of their preferences in spiritualistic practise. These gods aren't 'real' per se, but they are real in the sense of spiritualistic practise. Through the mind, they become a reality of a different level. Some traditions, like buddhism don't bother outright with gods and deities, but they do have mythical creatures which is merely a weaker version of gods because of their weaker emphasis on authoritative methods of stimulating emotions to achieve altered states of consciousness.
Where do drugs come into the picture here? Regardless of being often mistaken for the actual spiritual subject, mushrooms, LSD and other drugs (not necessarily hallucinogenic in nature) mere act as enhancers. How so? The emotional impact one has using either of those previously mentioned methods CAN be much stronger under the influence of drugs. Particularly, psychedelics are useful for having a direct effect on the mind. It also makes it the least predictable. Basically, drugs are like buffs that enhance your emotional uptake, no matter which method you're using. Though effective, drugs, especially when using higher doses ir intense ones such as dature, can be detrimental to the mind and are utterly unpredictable sometimes. They can backlash and could therefore be considered as applying 'black magic' though without the stigma of it being 'evil'. It is simply another path.
So there you have it. All this from analysing the placebo effect. Any input? Thoughts?
