One of the side effects of doing research into the byways of occultism is that every so often something very interesting comes up. Recently I did a lot of digging into 20th century American occultism, in order to chase down the background of those interesting exercises, the Five Rites. A book on the subject,
The Secret of the Five Rites: In Search of a Lost Tradition of Western Inner Alchemy, will be out this fall, but in the meantime I have a few useful things to share. The material below is one of them.
The Eye of Revelation, the 1939 pamphlet that originally made the Five Rites public, was published (and partly written) by a remarkable Los Angeles occultist named Harry J. Gardener. During the 1940s and 1950s, he was apparently part of a Rosicrucian magical lodge I'm still tracking down -- it doesn't seem to have been affiliated with any of the known Rosicrucian orders -- and his voluminous writings include various tidbits of spiritual practice I've never encountered elsewhere. (The star, circle and triangle logo above and to the left was apparently the emblem of Gardener's lodge; if anyone else has seen this elsewhere, I'd be most interested to hear about it.)
One of the practices Gardener taught was a breath and movement exercises he called the Rising Call. Here's how it's done:

"The exercise is as follows: Standing erect, place the right thumb against the right nostril, allowing the fingers of the hand to extend upward in line with the forehead. Now through the left nostril completely fill the lungs with air. Then with the index finger of the same hand close the left nostril also.
"With the lungs filled and the lips partly open so that there will be no pressure in the mouth, bend over from the waist, getting the head lowered as far as is conveniently possible. Then allow a portion of the air in the lungs to gently come back into the nose so as to create just a very slight pressure there. This position allows the blood to flow into every part of the brain which, along with the air in the lungs, has a very energizing effect upon the entire system and especially upon the sensitive nerve centers of the brain.
"When the desire to resume breathing is quite strong, rise to the erect position, then close the left nostril and allow the breath to escape through the right nostril by removing thumb. Do not force it out with great speed; nor should you retard it to any great extent. Just let it flow out freely and naturally until the lungs are emptied without forcing out the last particle of air through sheer force.
"Now, with positively no intervening breaths—in other words, with the very next inhalation of air—repeat the process. Close the right nostril with the right thumb; inhale through the left nostril; close both nostrils; bend over until ready to exhale; then stand erect; remove the thumb from the right nostril and exhale. Do this three times. That is, you fill the lungs three times, you hold the breath and bend over three times, and you exhale three times."
-- Harry J. Gardener,
Streamline Minds (1936)
One thing Gardener says elsewhere in the book, which is worth repeating, is that this is done
only three times per session, and only one session is done per day. More than that can be too much. Also,
do it gently; there are no prizes for using excessive force.
What's interesting to me is that this is a very precise and gentle way to change the pressure in the cerebrospinal fluid. Your brain floats in a puddle of fluid, which is separate from the blood and held in by a set of membranes; the fluid is partly there as a shock absorber, but it also functions to carry hormones and neurotransmitters from one part of the brain to the other, and also from the pineal and pituitary glands to each other and to various parts of the brain. The Rising Call, by gently and temporarily increasing the pressure on the cerebrospinal fluid by increasing the blood pressure on the brain and then using breath pressure in the sinuses to add to that, seems to flush fluid through the brain's ventricles and around the periphery of the cerebrum and cerebellum.
It's supposed to have various beneficial effects. For the sake of an informal experiment, I'm not going to mention what those are just now -- I'll describe what Gardener says, and what my experiences have been, in a week or so. I will say that I've practiced this now daily for three months without any ill effects whatsoever, and with notable benefits. I'd like to invite readers to give it a try, and post whatever experiences they have as a result.
