Can we take relations between Pineal gland and Third eye, that are elaborated not only “esoteric” (haha) Buddhism, Hinduism, but also in New Testament (Matthew 6:22), Descartes, not to mention zillions of new age movements as metaphors only, or do they perhaps talk about something that can be universally (scientifically) approved?
We are thus talking about controlled connection between outside reality, human organ and human perception. With this organ (Pineal gland), that is for many reasons deactivated as functioning third eye in majority of people, we would see (perception), higher levels of reality. That is why I normally put reality in “”. I would not like to induce notion, that there is one reality only. Better: there are many layers of one reality (from the reality point of view), there is one reality with one layer (for each individual) and there are exactly so many realities as there are individuals that are observing it. If confused, you can refer to Dan Dennett “Multiple draft” theory.
I argue that scientific confirmation of mentioned relations is not only possible, but in fact necessary.
The fastest way to show this necessity is to ask ourselves: how come that this connection was not yet scientifically established? Not only, it was not established, it’s possibility was ridiculed in all mainstream post cartesian science. The explanation is quite simple: If you take for granted, that what humans perceive IS a the highest level of perception of reality, then all other options are out of question. Our science strives to SEE (with existing 2 eyes with the help of reliable tools like microscopes, telescopes…) smaller and smaller and bigger and bigger. Our eyes (hepled by cognitive power of brains and developed tools) present the limitation factor of reality. Don’t we see the trap in the tool (organ)?
Let me help a little bit. Let us pretend that we are cats. Cats see in black and white. And there comes a cat that has heard that there exist an organ, called human eye, that can see a higher dimension which they, humans, call colour.
The main limitation factor to our development is the sad truth, that even 200 years after Darwin we can still not understand him. While we humans are are one of the latest evolutionary results that does not mean that we are ultimate result. What we do not SEE or what we do not expect to see with seeing (with our eyes), cannot exist even in theory. Science is prohibited to enter the field of third eye, since this is not of one of two existing eyes that are canonized as ultimate organs for perception of reality. That is why science is prohibited to enter in the field of spirituality (I do not confuse spirituality with religion!)
Evolution has no ultimate result. We are not a kind of fixed background for reality on which (us) the re reality could only be measured. All results of evolution are partial. Each participant (species, individuum, organ, cell…) in evolution has partial view on reality. Thus necessity of multiple draft theories. Thus we should be happy and eager if there exist an option that a new tool (organ) reveals a new draft of this reality. The fact, that I have not yet developed my third eye so that would serve to me as a sense organ is not an argument to refute its potentiality. It would be like refuting the validity of quantum mechanic since I do not understand quantum equations to the last detail neither have I ever seen quantum particle.
