III. The Pineal Gland — The Eye That Never Closed.

If the hypothalamus is the conductor, the pineal gland is the mysterious oboist seated at the back of the orchestra—the one no one really looks at, but whose melody permeates everything else and gives the concert its secret dimension. Modern biology treats it with a certain nonchalance: a small gland the size of a grain of rice, nestled in the center of the brain, producing melatonin, regulating the circadian rhythm. Nothing more, nothing less. Science sees it as a biological clock. Esoteric tradition, however, sees it as the monocle of heaven—the eye of God, misunderstood by modern biology.

René Descartes, the philosopher always cited for his rationalism but often forgotten for his subtle mysticism, asserted that the pineal gland was the seat of the soul, the point of connection between the res cogitans—the thinking thing—and the res extensa—the extended, material thing. He may have been right, but for the wrong reasons. For the pineal gland is not simply the seat of the soul in the philosophical sense: it is the subtle relay, the transducer between the frequencies of the physical world and those of the higher planes. It is the third eye spoken of by all traditions without exception—from the Ajna chakra of Tantric yoga to the Eye of Horus of ancient Egypt, whose anatomy reproduces with unsettling precision the configuration of the pineal gland surrounded by the thalamus.

 This “flame of fire” is not a war metaphor: it is the description, in the symbolic language of the Apocalypse, of a consciousness whose third eye is fully awakened, whose pineal gland vibrates at its maximum frequency, unfiltered, unveiled. And it is here that autism enters the conversation in the most fascinating way possible.

In an esoteric interpretation consistent with available biochemical data, autistic individuals would have a less calcified pineal gland than average—or, more precisely, a gland whose social filtering mechanisms, operated by the left hemisphere of the brain and its conventions, would be less restrictive. The calcification of the pineal gland, observed from adolescence onward in most modern adults under the influence of fluoride, artificial light, and chronic stress, is symbolically equated with the progressive closing of intuitive consciousness. Autism, within this framework, can be understood as a form of natural decalcification —a state of raw, uncensored reception, where the veil of Maia, that fundamental illusion that leads us to believe the physical world is all that exists, is thinner, more transparent, sometimes almost nonexistent.

It is not a privilege without cost. Seeing through the veils is exhausting when the world around you has built its entire social architecture on the solidity of those same veils. But it is a vision. An authentic vision, of a depth that those who have never experienced this state of heightened perception can only glimpse, like gazing at the sun—briefly, with half-closed eyes, with a mixture of awe and wonder.

IV. The Astral Body — Traveling Without a Ticket

In the Hermetic tradition and in the writings of Theosophy, there exists a concept that pragmatists find irritating and poets find inevitable: that of the astral body. This luminous double , this garment of light that the soul dons between incarnations—and even during them—is described in many traditions as the seat of emotions, dreams, and perceptive faculties that transcend the five ordinary senses. It is not the physical body, although it is superimposed upon it like a tracing of light on a map.

In most incarnated human beings, the astral body is firmly anchored to the physical body by what Eastern traditions call the silver cord—a subtle link, almost a benevolent cosmic leash, that prevents the soul from straying too far from its earthly abode during sleep. But in some souls—and autistic people seem to belong to this category in remarkable proportions—the anchoring is less firm. The astral body is, so to speak, a frequent traveler. It takes unscheduled excursions. It returns with impressions that the physical brain struggles to translate into words.

Perhaps this is the most compassionate key to understanding the characteristic “absences” of autism. These gazes lost in the void, these moments of apparent disengagement, these profound reveries in the middle of a conversation: are they not, in reality, excesses of presence on another plane rather than deficits of attention on this one? The autistic soul does not absent itself. It shuttles back and forth. In this sense, it is the most adventurous passenger in Creation—the one who travels without a ticket because it has known the conductor since before birth.

 In this interpretation, blood types also play a significant role in how the astral body interfaces with the physical. Blood type A, with its physiological constitution more susceptible to inflammation and its reflexive nature, seems more porous to astral influences—as if the boundary between its bodies were naturally thinner. Blood type B, on the other hand, manifests a more telluric energy, more rooted in biological rhythms and instinct. Blood type O, especially Rh-negative, presents a particularly interesting configuration, which we will discuss in the following section. These correspondences are not dogmas—they are intuitions to be explored with discernment, symbolic clues in a landscape where biology and symbolism finally speak the same language.
