The ability to perceive into the supernatural realm may be related to brain chemistry surrounding the pineal gland. The pineal gland is small and shaped like a pine cone, and is in the deep recesses of the brain. It produces various hormones related to sleep, sex, and growth.
Many religions consider it the gateway to spiritual awareness and it’s been called the “third eye” and the “seat of the soul.” Much mysticism surrounds it. The hype is probably overblown and frankly, its functioning and total purposes aren't completely understood by modern science.
Peer-reviewed research demonstrates that manipulating the pineal gland in certain ways can impact the development of the sex organs while producing giantism.
It is one of the few parts of the brain that is not isolated from the blood stream. Both spinal fluid and blood flow strongly through the pineal gland.
ABUSING THE PINEAL GLAD
Western diet, fluoridated water, and constant visual attacks (e.g., television programming) might tend to calcify or numb the pineal gland’s ability to function. Speculatively, maybe this is why some people can “see” as children, but as they age, they lose their ability: their pineal gland has been so blunted by pollutants generated by Western society.
A drawing of the Pineal Gland
Some drugs seem to act on the pineal gland, instantly shutting it down. This is why when some seers go to “get help” with something like depression, and a doctor prescribes anti-depressants, the “seeing” stops. But when they go off the drugs (to deal with the depression in other ways), the "seeing" returns.
But then, maybe the drugs aren't affecting the pineal gland specifically, but brain chemistry in general.
I know a seer who was afflicted with migraines, and took certain migraine medication, only to find her ability to see in the spirit realm stopped. The questions she had to answer was simply: is it worth not seeing into the spirit realm to live pain free? It was, although she felt some fear never knowing if a room was "safe" or not, because she couldn't perceive into the spirit realm anymore.
Eventually, her doctor switched medications, and a few weeks later, her ability to perceive the spirit realm returned, while the migraines stayed away. I haven’t been able to locate research to indicate if some of these drugs impact the pineal gland, but I suspect they impact brain chemistry generally.
Speculatively, some drugs radically “open” the pineal gland in negative ways. People on LSD and other drugs (such as potent, refined marijuana) report seeing very frightening things. It's difficult to know if the hallucinations are just hallucinations or if they are really seeing something in the spirit realm. It's difficult to know if the reason they see things is because of the pineal glad or because the drugs impact various parts of brain chemistry.
Activating the Pineal Gland
Much mysticism abounds relating to "activating the pineal gland." Perhaps the pineal gland is stimulated when people pray to God or other spirit beings, when they use certain drugs, when they meditate, and for other reasons.
Perhaps it metaphorically opens a window or portal into the spirit world. It enables all of us to have mystical experiences (without drugs).
Cleansing the Pineal Gland
There is much advice on the Internet about the need to "cleanse" the pineal gland. I saw one image shared on social media with 15 herbs that "decalcify" (or remove calcium buildup) from the pineal gland. Ostensibly, you'd want to "decalcify" the pineal gland to have better spiritual experiences.
I'm reminded of a passage from the Book of Enoch, which describes the Watchers who came to earth in the days of Enoch. A Watcher is a powerful guardian spirit who was supposed to watch over a territory in protection. These particular Watchers "saw and...
