These days I spend most of my time compiling and aggregating the Meows and Cat Reports. But what is much more important to Douglas and me as we go forward with you on our journey to truth is that you know how amazing the HEART is. While many spiritual teachers will direct you to opening the third eye, the pineal gland, they skip over the importance of activating the HEART which is a supersensible organ of perception is. We want to teach you how to open yours, too!

The heart is like the Sequoia tree seeds and can only be opened with intense fire. To translate this in human terms, it takes great suffering to open the heart to unfold its true radiance, a process which can take several lifetimes until you, with your tiny heart seed, become a human as grand as a sequoia tree.

If you are suffering now, whether physical, emotional, or spiritual, perhaps you are awakening the heart chakra to become more like Christ who suffered on the cross as a way to show you the human condition which leads to ascension.

Your suffering has meaning for your human evolution.

Let’s continue to unpack Douglas Gabriel’s book on the heart. Once you comprehend the fundamentals of how the heart “works”, you can understand the how the heart is an organ of perception that the evolving human can activate and use in perceiving the world around them.


The Human Heart is a Supersensible Organ of Perception

Heart Rate Variability

The importance of heart rate variability cannot be overestimated because it is a clear indicator of heart health and longevity. One can even buy a device that measures heart rate variability that will fairly accurately assess the entire health of the body and make predictions about the length of life and the likely organ or systems that will break down first and lead to death. This amazing discovery is accurate and is the first of its kind to “predict” the health outcomes of the person being assessed.

Heart rate variability is a measure of the variation in the time between each heartbeat controlled by the autonomic nervous system. It works regardless of our desire and regulates, among other things, our heart rate, blood pressure, breathing, and digestion. Heart rate variability is a noninvasive way to identify autonomic nervous system imbalances. If a person’s system is in a fight-or-flight mode, the variation between subsequent heartbeats is low. If one is in a more relaxed state, the variation between beats is high. In other words, the healthier the autonomic nervous system, the faster you are able to switch gears, showing more resilience and flexibility. Research has shown a relationship between low heart rate variability and depression or anxiety. A low heart rate variability is associated with an increased risk of death and cardiovascular disease.

People who have a high heart rate variability tend to have greater cardiovascular fitness and be more resilient to stress. Heart rate variability can provide personal feedback about your lifestyle and help motivate steps toward a healthier life. Heart rate variability changes as you incorporate more mindfulness, meditation, sleep, and especially physical activity into your life. It can track how your nervous system is reacting not only to the environment, but also to your emotions, thoughts, and feelings.

To determine your heart rate variability you analyze an electrocardiogram, or use apps and heart rate monitors that do something similar and download a free app to analyze the data. Other methods used to detect heart rate variability include: blood pressure, ballistocardiograms, and the pulse wave signal derived from a photoplethysmograph.

Reduced heart rate variability has been shown to be a predictor of mortality after myocardial infarction. A range of other outcomes and conditions may also be associated with modified (usually lower) heart rate variability, including congestive heart failure, diabetic neuropathy, post cardiac-transplant depression, susceptibility to Sudden Infant Death Syndrome and poor survival in premature babies.

Heart rate variability is the measure of the inconsistent gaps between each heartbeat and is used as an index for different aspects of psychology. It is reported to be an index of the influence of both the parasympathetic nervous system and the sympathetic nervous systems. Different aspects of psychology represent the balance of these two influences. For example, high heart rate variability is shown by proper emotion regulation, decision-making, and attention, and low heart rate variability reflects the opposite. The parasympathetic nervous system works quickly to decrease heart rate, while the sympathetic nervous system works slowly to increase heart rate. Heart rate variability has provided a window to the physiological components associated with our emotional regulation.

It has been suggested that increased attention has been linked to high heart rate variability and increased vagus nerve activity. The vagus nerve activity reflects the physiological modulation of the parasympathetic and sympathetic nervous system.

A reduction of heart rate variability has been reported in several cardiovascular and non-cardiovascular diseases; such as:

  • Myocardial infarction
  • Diabetic neuropathy
  • Cardiac transplantation
  • Myocardial dysfunction
  • Liver cirrhosis
  • Sepsis
  • Sudden cardiac death
  • Cancer


Frequency Rate of the Human Heart

Much is made of the measure of heart vibrations and frequencies. The ancients believed that the heart had a standard frequency that could be stimulated for enhancing health and longevity. There is much debate about which frequency is the ideal and what techniques and mechanism can “tune” the heart to the cosmic frequency of the Schumann Wave, the cosmic frequency of the revolving Earth. Tibetan bowls are tuned to the individual chakras and claim to create the proper resonance and coherence for the development of human consciousness.

The resting heart rate of a normal adult is between 60-100 beats per minute, depending on age and fitness level. This is calculated upon the heartbeat frequency (heartRatePerMinute/60). That translates to 1-1.67 beat per second, or 1–1.67 Hz, based solely upon the frequency of the human beat.

If you are talking about the electrical signals that cause the human heart to beat, the P and T wave frequency generally ranges between 0.5 and 10 Hz and QRS complex frequency between 4 and 20 Hz. If you are talking about the heart sound frequency, it is generally between 20 to 500 Hz. During sleep, the ideal breath to heartbeat rate is 1:4.

Here is a sample of Tibetan Bowls, which can be a nice background sound as you continue to read about the heart. There are many videos like this on the internet. Choose the ones that resonate with you.

The Heart’s “Pacemaker” – Atriosino Node

Ancient Hindu philosophy believes there is a “thumb of fire” in the heart that is the spiritual flame of the individual. This flame is created in the interaction of the lungs bringing oxygen (fire) to the heart. It is this flame that constitutes the seat of consciousness, or the mind of the individual. It is said that this flame is the cause of the heartbeat and is a replication of the cosmic fire found throughout the cosmos. Modern science has theories about the atriosino node causing this flame through the interaction of sodium and potassium interacting on the surface of this node.

A full examination of the atriosino node will not satisfy the questions about where and how the warmth (fire) of the heart is created. A more through and comprehensive theory is needed to truly understand the warmth in the blood and the heart and lung’s participation in creating this warmth.



The human heart beats more than 3.5 billion times in an average lifetime. The heartbeat of a human embryo begins at approximately 21 days after conception, or five weeks after the last normal menstrual period, which is the date normally used to date pregnancy in the medical community. The electrical depolarizations that trigger cardiac myocytes to contract arise spontaneously within the myocyte itself. The heartbeat is initiated in the pacemaker regions and spreads to the rest of the heart through a conduction pathway. Pacemaker cells develop in the primitive atrium and the sinus venosus to form the sinoatrial node and the atrioventricular node respectively. Conductive cells develop the bundle of His and carry the depolarization into the lower heart.

The human heart begins beating at a rate near the mother’s, about 75–80 beats per minute (bpm). The embryonic heart rate then accelerates linearly for the first month of beating, peaking at 165–185 bpm during the early 7th week. After peaking at about 9.2 weeks, it decelerates to about 150 bpm (+/- 25 bpm) during the 15th week. After the 15th week the deceleration slows reaching an average rate of about 145 (+/ -25 bpm) bpm at term.

Instead of getting into medical jargon about how the electrical system works in the heart, let’s turn to a simple explanation given by Kahn Academy:

The Anatomical “Box Around the Heart”

The most ancient stories of the Tibetans tell of a fiery box that fell from heaven to Earth bringing down the first treasures of their religion. Four objects were contained in this box that became the foundation of their beliefs. This box contained the begging bowl of Buddha, the cintamani stone (the jewel in the heart of the lotus), a book of wisdom, and the original design of the first stupa (temple). Until recently, few understood that this box is a reference to human anatomy that is often overlooked.

Around the heart is a series of organs that enclose it like a box and indicate that the ancients were unto a profound secret of the human heart that we now call the mediastinum.

This “cube” around the heart is the current “shape” of the heart container with its six sides defined by the directions of up/down, right/left, and forward/backward. In the future, this cube will evolve into a dodecahedron which has twelve sides that align with the twelve divisions of the Zodiac. From the current shape of the cube, to the future shape of the dodecahedron we find the morphological path that the heart will follow in its development. This sacred shape, inscribed by the cube, is the inviolable home of the human mind that is referred to as the “jewel in the heart of the lotus”, or the cintamani stone. It is the “rock” that human consciousness is built upon, the cornerstone of the holy of holies in the heart-of-hearts.

The mediastinum lies within the thorax and is surrounded by the chest wall in front, the lungs to the sides and the spine at the back, essentially creating a “box” around the heart. It extends from the sternum in front to the vertebral column behind and contains all the organs of the thorax except the lungs.

The “Box” Around the Heart


The four directions of the heart are: above/below (up-down), front/back (forward-behind), and the chambers of the heart representing left/right working with the lungs. Thus, the heart is surrounding by a virtual “cube” that is indicated in the “box” of the mediastinum’s component parts listed below:

  • superior mediastinum – above the pericardium,
  • inferior/middle mediastinum – holds the pericardium from below,
  • anterior mediastinum – in front of the pericardium,
  • posterior mediastinum – behind the pericardium.



In GA 205 (July 2, 1921) Rudolf Steiner says:

“You can imagine what a tremendous difference there is, between that which lives in our heart during this incarnation and the condition in which we find ourselves in a new life after having gone through a long development in the time between death and a new birth. And yet when you look into your innermost heart you can assess quite well, of course in a hidden way only, not in a fully developed imagination, what you will do in your next life. One can, you see, not only say in an abstract way, my next life is being prepared today in all karmic detail, but one can point to the ‘little box’ in which the karma rests, awaiting the future.”

Blood Types

While everyone’s blood is made up of the same basic parts, there is a lot of variety in the kinds of blood that exist. There are eight different blood types, and the type you have is determined by genes you inherit from your parents. What makes your blood different from someone else’s is your unique combination of protein molecules, called antigens and antibodies.

Antigens live on the surface of your red blood cells. Antibodies are in your plasma. The combination of antigens and antibodies in your blood is the basis of your blood type.

Blood typing is particularly important for blood transfusions, because certain antigens on blood cells can trigger a person’s immune system to attack the donated blood. People who are Rh-negative can only receive Rh-negative blood, but people who are Rh- positive can receive either Rh-positive or Rh-negative blood.

What’s more, type A blood can be used for transfusions for patients with type A or type AB blood; type B blood can be used for patients with type B or type AB blood; and type AB blood can be used for patients with type AB blood. People with type O blood are called “universal donors” because this type can be used for patients with any blood type.

Type O blood is often in short supply in hospitals, due to demand for this universal donor type. In particular, type O-negative blood is in high demand because it’s the one most often used for emergencies, when there may not be time to determine a patient’s blood type.

Blood Types and Nutrition

Peter J. D’Adamo, N.D. does a marvelous job of aligning blood type with nutritional needs and lifestyle in his book, Eat Right 4 Your Type. Below is an extracted summary of his insight:

“Blood type, with its digestive and immune specificity, is a window on a person’s probable susceptibility to or power over disease. For example, Type O’s are the most likely to suffer from asthma, hay fever, and other allergies, while Type B’s have a high allergy threshold, and will react allergically only if they eat the wrong foods. Type B’s are also especially susceptible to autoimmune disorders, such as chronic fatigue, lupus, and multiple sclerosis. Type AB’s tend to have the fewest problems with allergies, while heart disease, cancer, and anemia are medical risks for them.

With arthritis, Type O’s, again, are the predominant sufferers because their immune systems are “environmentally intolerant,” especially to foods such as grains and potatoes which can produce inflammatory reactions in their joints. Types A and B are the most susceptible to diabetes, while types A and AB have an overall higher rate of cancer and poorer survival odds than the other types.

Type O – People with type O blood fare best on intense physical exercise and animal proteins and less well on dairy products and grains. The leading reason for weight gain among Type O’s is the gluten found in wheat products and, to a lesser extent, lentils, corn, kidney beans, and cabbage. Ideal exercises for Type O’s include aerobics, martial arts, contact sports, and running.

Type A – Those with blood type A, however, are more naturally suited to a vegetarian diet and foods that are fresh, pure, and organic. As Type A’s are predisposed to heart disease, cancer, and diabetes. Type A’s can derive significant benefit from calming, centering exercise, such as yoga and tai chi.

Type B – Type B’s have a robust immune system and a tolerant digestive system and tend to resist many of the severe chronic degenerative illnesses, or at least survive them better than the other blood types. Type B’s do best with moderate physical exercise requiring mental balance, such as hiking, cycling, tennis, and swimming.

Type AB – Blood type AB, the most recent, in terms of evolution, of the four groups and an amalgam of types A and B, is the most biologically complex. For this group, a combination of the exercises for types A and B works best.”
