The heart is truly a double pump.
One side of the heart pumps blood in one direction while the other pumps blood in the opposite direction. These two pumping directions complement and harmonize each other wonderfully.
The most interesting thing about the two opposite blood streams pumped by the heart is that they do not collide but help each other to advance together.
The heart is truly the sun of our organism.
The heart is the greatest wonder of creation.
Nevertheless, there are eminently cultured and educated people who do not know the physiology of the heart.
It is something to admire, to see the passage of blood through that swift river of the aorta.
This artery is truly a mighty and beautiful river.
We are filled with admiration and mystical beauty when contemplating that grand river full of life. This grand river ramifies into minor rivers, small arteries and then into small creeks that carry life to all parts, to nourish and give life to millions of small micro-organisms (cells, genes, etc.)
All those organisms are triads of matter, energy, and consciousness.
All those beings of the infinitely small adore us like a God.
The smallest creeks of the blood are the capillary vessels.
The cells of the diverse tissues and organs are found inside the weft of the capillary networks.
Thus, the cells live from the blood streams pumped by the heart.
The cells are composed of molecules and these of atoms.
Each atom is a true universe in miniature.
Every atom is a triad of matter, energy, and consciousness.
The NOUS atom, which lives in the left ventricle of the heart, governs the atomic intelligences.
The aspiring atoms of the heart obey orders of the NOUS atom and transmit them to the engineer atoms that conduct the activity of each organ.
The atomic workers of each organ obey orders from the engineer atoms and work according to those orders.
There also exist a multitude of indolent atoms that are the cause of diseases.
The NOUS atom of the Heart works under the direction of the architect atom and the latter under the orders of the INTIMUS.
The heart is a shallow muscle about the size of the fist, that looks more or less like a pear.
The heart contracts, expands, and relaxes incessantly. This is the ebb and flow of the grand ocean of life.
Every life has its systole and diastole. Everything ebbs and flows in the infinitely small, as well as in the infinitely grand.
“As it is above, so it is below.”
“As it is below, so it is above.”
This is the law of the great life.
In the heart are two wonderful polarities: positive and negative. These are like two hearts incessantly pumping blood into two opposite directions.
The two compartments of the heart have two chambers, a superior and an inferior.
The superior chambers are the atria, and the inferior chambers are the ventricles.
The secret doctrine recognizes seven secret chambers in the heart and seven secret cavities in the brain.
There is a right atrium and a right ventricle.
There is a left atrium and a left ventricle.
The superior chambers from right to left are the atria.
The inferior chambers from right to left are the ventricles.
Meditating on the Lotus of the Heart, we control the Tattva Vayu [or Principle of Air], and the power over winds and hurricanes is granted.
The Hindustani state that the lotus flower of the Heart has twelve wonderful petals.
The whole intimate functionalism of the heart, its whole vital profoundness must be sought in the lotus flower of twelve petals whose subtle stem emanates from the heart temple.
The vena cava, full of organic wastes, deposits blood into the heart.
The right atrium receives the impure bloodstream and wisely passes it to the right ventricle that is beneath.
A few instants later, the right ventricle pumps its blood charged with lymph and wastes through its valve to pass it to the interior of the lung by means of the pulmonary artery.
The cosmic intelligences have not neglected anything.
It is interesting for the sage to contemplate this whole functionalism.
It is wonderful to see the great pulmonary artery divide itself into the two smaller arteries, one for each lung.
Inside the lungs, the pulmonary arteries ramify also, until they become minute capillary vessels.
Each drop of blood has to inevitably pass through the capillary vessels of the lungs, where it delivers the excess anhydrous carbon and absorbs, in exchange, the excess oxygen.
The rich oxygenated blood penetrates intelligently into the small veins and then to the larger veins.
The two great pulmonary arteries deposit their rich blood charged with oxygen into the left atrium of the heart.
The blood has exchanged its excess of anhydrous carbon for oxygen.
Now with life renewed from the left atrium, the blood passes to the left ventricle and then through the aorta under the rhythmic impulse of the heart and follows at last into all the arteries and sangineous vessels.
In all this work we can see the intimate relationship between Vayu the air principle and the heart.
Therefore, the Hindustani are not too far off when they associate Vayu [or Principle of Air] with the heart.
This demonstrates to us the profound Physiological-cosmic knowledge that the easterners possess concerning the organ of the Heart.
Why do the westerners not want to study the eastern Yoga ?
Why do the Westerners want to laugh at what they do not know?
It would be wiser to study Sivananda, the great yogi. (The book entitled “Kundalini Yoga” is a prodigy of eastern wisdom.)
Those who wish to put their body in a Jinn state, those who want to learn to put their physical body in the fourth dimension, must develop the lotus of the heart.
A yogi with their body in a Jinn state can fly through the air, walk on water, as Jesus Christ did on the Sea of Galilee, or walk through fire without being burned as many yogis of India do.
A yogi with their body in a Jinn state can go through rocks as the disciples of Buddha did.
The lotus of the Heart develops with meditation and prayer.
The Western doctors say that the heart produces two sounds, one low pitched and muted and the other loud and high pitched: “Lub” and “Dub”.
The physiologists assure us that the first sound is pronounced immediately after the contraction of the ventricles, and that the second is due to the closing of the valves that separate the ventricles of the aorta and the pulmonary artery.
The Hindustani doctors go further because they have refined their senses. The yogis of India state that in the heart there are ten mystical sounds.
“The first is CHINI (like the sound of that word, like the voice of the Son of Man);
the second is CHINI-CHINI [or CHINBINI];
the third is the sound of (the great cosmic) bell;
the fourth is that of conch (the internal thundering of the Earth);
the fifth is that of tantri (lute);
the sixth is that sound of tala (cymbals of the gods);
the seventh is that of (enchanted) flute;
the eighth is that of bheri (big drum);
the ninth is that of mrdanga (double drum);
and the tenth is that of clouds (thunder, the sound of the seven thunders that in the apocalypse repeat the voices of the Eternal One).” [from the Hamsa-Upanishad]
If the sounds heard by the western doctors are true, why can the ten sounds of the easterners not be true?
If the two sounds of the western doctors have been demonstrated, why should the ten eastern sounds not be demonstrated?
Everything is a question of demonstrative scientific procedures.
The westerners have their demonstrative scientific procedures. The easterners also have their demonstrative scientific procedures.
The easterner concentrates mentally and meditates on the ten mystical sounds.
The Asian mind absorbs itself in the ten mystical sounds. Hence, the yogi’s “nissus formativus” or the protoplasmic Astral body of the medieval doctors (within which there are all the psychic and spiritual principles of the human being), leaves the physical body in ecstasy within the ten mystical sounds of the heart.
This is the Samadhi of the Hindustani yogis. Thus, this is how the yogi transports themselves to the most distant worlds of the infinite.
Instead of laughing and criticizing these matters that they have neither studied nor experimented, the Western scientists should study yoga.
The Hindustani state that inside the Chakra of the Heart there is a hexagonal space of an ineffable black color. The ten mystical sounds are there.
Western minds laugh at all this. If the western scientists would develop clairvoyance, they would see, and stop laughing.
Doctors are able to photograph the heartbeat with the instrument called the Electrocardiograph.
It is wonderful to see how they totally synchronize all the heartbeats, all the chambers, as if there were only two. This is only possible thanks to a handful of nerves.
This handful of nerves, also called the ventricular atrium, automatically synchronize in a wonderful form the two atria in a single weak heartbeat contraction, and the two ventricles in a single strong heartbeat contraction.
If the Electrocardiograph is capable of photographing the heartbeats, how much more would he who develops clairvoyance see?
A new world opens before the clairvoyant, an infinite world of immeasurable variety.
Within the heart is the internal Christ of any human being who comes to the world.
He is our real Being.

Fundamental Notions of Endocrinology and Criminology by Samael Aun Weor
Practice for bringing Aspiring Atoms to the NOUS Atom
…when out of the body the student must try to remember what they have seen, and this is difficult; for if they will try to visualise the entrance to thier front door, they will be surprised to know how little they have observed.
…In our trips out of the body the visions of the interior planes are more difficult to see than those of the physical; for the finer essences of Nature are more subtle. Our methods of reading —especially newspapers— in time impairs our powers to think about what we have read, and to remember it with precision.
This power to see with one’s third eye is not what is usually called a spiritual gift, and this can be developed in the same way that an athlete can develop their muscles. There are many centres seemingly atrophied from disuse within our bodies; these can be awakened to a normal condition by this Yoga practice.
We again remind the student that they must use common sense in these things, particularly in their food and sleep…
…Before beginning your breathing exercises take a drink of water; for we should remember that the body will take as much water as we will give it. It is often thirsting for it, as otherwise it cannot clear itself of its impurities. We should drink fresh water between meals and keep a pitcher where we can see it. …The water we take acts as a filter, and the positive atoms find it easier to communicate when the stomach is clean and full of water.
In your breathing you will quickly notice that you inhale in one side of the nostril at a time, and you will learn to change the current of your breathing from one side to the other as you wish.
There are many different types of atoms to attract and place in their proper position on the membranes— that plate the occultist calls the magnetic field—we attract one kind at a time, and the type we build with mostly are the Aspiring atoms. The passages in the nostril are known as the Sun and Moon passages; and the Aspiring atoms enter the right passage. Later, when we try to attract the atoms of the Lunar force we breathe through the left nostril.
…The reason why Western bodies cannot adopt Eastern Yoga methods successfully is because we live in a Northern atmosphere, and the currents change as they approach the Equator.
 In the first exercise sit erect with chin in and chest out, hands clasped with the thumbs crossing each other: the reason being that no obsessing force of a psychic nature can enter. Do this whenever practising.
Aspire inwardly with the utmost purity of thought, and as you inhale think of the word “Aspire”. Do this six times with the mind centred upon the root of the nose; for behind it lies the magnetic field that collects the Aspiring atoms.
 …Repeat the same exercise, holding the breath for an instant whilst concentrating upon the magnetic field, then send the atoms collected there down to the Nous atom in the heart.
By this method we call upon the Nous atom to respond and the first time it does so the student may feel a slight pain in the heart. This exercise should be repeated daily at regular times, and in about two weeks one should feel a sensation of heat on the magnetic field. This is a process of building a bridge of communication between the inner and outer worlds by means of atomic substances.
When Aspiring send all your love to the Nous atom and its workers, and listen for a response. When this occurs these atoms rejoice, for, as Initiates say, “There is joy in Heaven”. For now we begin to journey inwardly and place our feet upon the Path of realisation.
The response will not be in words or sounds, but a thought-emotion that we learn to translate into words. So with practice we shall in time bring through clear and definite instruction. As we have said elsewhere, our true information comes from within and not from without.
This exercise is all that is needed to deal with the Aspiring atom. The Nous atom collects them into its atmosphere, and distributes them through the bloodstream : a foreign invasion of atoms of a higher vibration than the vibration the body normally responds to, and these attune us to that higher wave-length of intelligence we call the Dayspring of Youth.
Whatever you do in your daily work put your aspiration into it until it becomes a habit. This will bring out your constructive powers.
When the workers within your body receive aid and instruction from the more advanced type of atom, they are immediately stimulated to a greater activity and take on themselves the characteristics of those more developed atoms who inspire them to seek closer union with their Innermost. Hence the physical body is no longer indolent, but receives a new life and vitality; for the atoms that respond go through a transformation period.
The Aspiring atoms predominate in the human system and also in the seminal system, and assist in the building up of the procreative elements. If we can converse with these Aspiring atoms we can then send our thoughts into the groups and sections they sure developing. And as we increase their energy by Aspiration breathing we bring into their sections our more advanced type of Aspiring atom, and this gives them happiness: for they gain a period of upliftment and, as this also increases their energy, our body benefits. This is reflected back into our minds, and for the first time we feel that they respect us.
This increase of energy causes the indolent atoms within our secondary system and physical body to respond also.
When we vibrate to the intelligence within the Silver Shield it sends to the Aspiring atoms an added appreciation of their efforts, and from that moment we feel an individual responsibility for their welfare.
After the first steps we begin to aspire for another kind of atom called the Transformation atoms, that bring about what we call “Rebirth”, for we are transmuted into another kind of substance. Though before this happens we have to pass through our inner schools of instruction to which our Aspiring atoms have introduced us, and our progress depends upon our quickness in reviewing our past lives. This is a process similar to the embryo in the womb that draws upon its material from its past development.
The student will naturally want to know what is meant by school of instruction. We have six big centres in the body: atomic substances similar to star clusters called in the East the “Petals of the Lotus”. In time these centres will open to us and reveal intelligences that will re-experience us through our past lives. For the student cannot attain any great achievement without a knowledge of these inner universities and the forces within the Sun and the moon.
