[...] modern neurological research has confirmed that meditation increases the levels of DHEAS and melatonin, secretions produced by the pineal and pituitary glands which together are said by occultists to create the Third Eye.
There the pineal gland represented the sun, and the gland which could modify and reflect on the visions that the pineal gland received from the spirit worlds was the pituitary gland.
The Egyptians clearly depicted it [the pineal gland] as a uraeus snake and in Indian literature it is shown as the Third Eye of Enlightenment, or the Eye of Siva. It was depicted as the pine-cone-topped want of the followers of Dionysius, and a fourth-century BC Greek anatomist described it as 'the sphincter which regulates the flow of thought'.
Later it was discovered that the pineal gland is large in children and when the crystallization of various body parts happens around puberty - that is to say when we naturally become less imaginative - the pineal gland begins a process of calcification and also shrinks.
The pineal gland is a small grey gland, the size of an almond, which is situated in the brain where the spinal chord reaches up into it. In esoteric physiology, when we have a hunch, our pineal gland begins to vibrate, and if spiritual disciplines are used to increase and prolong this vibration, this may lead to the opening of the Third Eye, situated, of course, in the middle of the brow.
As far back as 2180 BC, the pharoahs were using the schefa-food to enhance their pineal activity and thereby to heighten their perception, awareness and intuition...
We are all surrounded and bombarded by thought-fields, and the thoughts we claim as our own are like a continuous universal broadcast. Some thoughts are cosmic in origin, while others are like local stations. The pituitary gland is the primary radio-receiver, channeling all wavebands and frequencies. It transmits selected frequencies (through secretions) directly to the pineal gland, which then amplifies certain broadcasts for transmission throughout the body. The pineal gland has total control over what it will and will not transmit through its controlled manufacture and release of the melatonin hormone. High melatonin production thereby increases the facility for receiving and transmitting high-frequency cosmic and local broadcasts, and leads to a greater state of cosmic awareness - a state simply of 'knowing'. In this regard, it is interesting to note that the Pineal Third Eye has been found to contain very fine granular particles, rather like the crystals in a wireless receiving set.
Exposure to an excess of natural light makes the pineal gland smaller and lessens spiritual awareness, whereas darkness and high pineal activity enhance the keen intuitive knowledge of the subtle mind, while reducing the stress factor.
Kundalini (the magical power of the human organism) is awakened only by will, and blood is the vehicle of the spirit. The pineal gland is the channel of direct spiritual energy and can be motivated by constant self-enquiry.
...the central staff and serpents represent the spinal cord and the sensory nervous system, while the two uppermost wings signify the brain's lateral ventricular structures. Between these wings, above the spinal column, is shown the small central node of the pineal gland. The combination of the central pineal and its lateral wings are referred to in some Yogic circles as the 'Swan', and the Swan is emblematic of the fully enlightened being.
