The third eye is among the concepts that find significant resonance in mysticism. Scientific explanations tell us that it was an important organ in cold-blooded creatures at the earliest stages of evolution, due to their sensitivity to light; as evolution continued and the transition to warm-bloodedness occurred, it lost its importance and its function of relating to light was transferred to the eyes. However, scientific explanations also tell us that this remnant of the third eye, the pineal gland, plays a very important role in our lives through the melatonin and other hormones it secretes (pinoline and dimethyltryptamine). Melatonin, while being a sleep regulator, also serves as a planner for both the 24-hour cycle and the long human lifespan. Its levels are responsible for the onset of puberty and aging, or for delaying aging. Dimethyltryptamine, on the other hand, is called the "spirit hormone"; it serves as a foundation for spiritual activities. When Descartes referred to the pineal gland as the seat of the soul, he was alluding to the spiritual experiences that occur through the stimulation of this region and the secretion of this hormone. It is a highly enjoyable subject; it is possible to delve deeper.
However, the subject of this article will be about theories of the third eye continuing to evolve. Mystical discourses about the third eye claim that those who have this eye opened will have mastery over the unseen, will be able to see and hear things that ordinary people cannot, and will even perceive people in different colors depending on their emotional states. I do not know whether there have been people in the past or present who have had their third eye opened; but we must remember that in prehistoric times, the function of this organ was more primitive than it is today.
We do not know whether humanity will have enough time in this world we live in to continue evolving. Nor do we know whether evolution will be as slow as it was in the past. However, the other day, a documentary was explaining how our surroundings are now covered with electromagnetic waves that did not exist a century ago, and that these waves are everywhere even though we cannot see or hear them. We, for our part, are bringing about a communication revolution by developing devices that produce and detect these waves. Cell phones, tablets, televisions, etc., etc. Could it be that the human body might one day develop organs capable of detecting these waves without any intermediary? Or even organs that both produce and detect them? Even if not naturally, it might be possible in the future to develop a communication protocol to implant these receptors into the body and transmit the signals they receive to the brain. In other words, in the future, we will have antennas. The disgusting cliché of Turkish teenagers and teenagers-at-heart adults—"Let those who can't stand me get an antenna" (or "let them get on my wavelength" ) —might just become reality.
If evolution is to happen, it can come from here on. Devices implanted in the body could evolve over time. Or the pineal gland could contribute to this evolution. I came across this article on Ekşi Sözlük. Although not exactly about this subject, it explains that pineal gland activity is affected by electromagnetic activity.
But what would this evolution be good for? It could enable us to see frequencies beyond the range that the human eye can perceive—perhaps infrared, perhaps ultraviolet, or maybe both. Thus, it would become possible to see angry, sad, or loving people in different colors. This organ could serve to detect and even produce electromagnetic waves, so that instead of our cell phones, we could transmit images and thoughts from our minds to each other over long distances through this means. This would be the realization of what we call telepathy. If our thoughts, including messages we do not wish to send out, also produce themselves with similar waves, the doors to mind reading would be opened.
Some of these things can already be achieved with existing technological devices. Historical figures from the past who are said to have performed such miracles certainly did not achieve this evolution. One possibility is that similar devices were seen from an advanced technology but were tried to be explained with the knowledge level of the time; another possibility is that these accounts never went beyond hearsay.
