Yoga has been an important part of my life in the last five years. I practice regularly, and recommend it often to my massage clients. When I started working on this post, I wanted to discuss the mutual benefits of massage and yoga. I believe strongly that the two complement each other, as I have experienced the benefits of both in my own life. For me, there is no denying an energetic connection with my clients. It is a similar type of energy I feel within my own body when doing my yoga practice.
It has only been in the last couple of years that I began thinking of chakras as something beyond metaphysical hooey and pretty colors. I come from a background rooted in “show me”. If I couldn’t see it, feel it, taste it or in some way have tangible connection to it, it fell into that category that belonged to sorcerers and snake oil salesmen. Imagine my delight when, on first accepting that at least understanding what they are and what they represent wasn’t a threat to my concreteness, now I have actually found resources that indicate that there are very tangible connections to highly charged nerve centers, called plexii, and by extension, muscular and immune function and hormone production, correlating to their locations and the properties assigned them.
For those of us less familiar with chakras, I will give a brief description of what and where they are, and what aspects of the person they represent. From there, we will look at their connection to the physical body.
In Ayurvedic and Yogic tradition, energy, or Prana, is the main life force. It travels along vessels, called nadis, and gathers in centers where these nadis come together. These gathering points are called chakras, a sanskrit term which means “wheel”, describing the circular movement of prana at these merging points. The concept has some similarities to the meridian system used by the Chinese in their medical system, with distinctions, one particularly important to this discussion. Where the Asian meridian system follows unique lines in the body, the yogic view follows the nervous system fairly closely, with nadis traveling throughout the body similar to nerves, and chakras again located at observable nerve centers where there is significant, measurable electrical energy.
There are 7 main chakras, with hundreds of smaller ones throughout the body. The 7 main chakras are the ones most focused on, and they will be the ones described here. Similar to the nervous system, there is a central nadi, with numerous branches stemming from it. This central nadi follows the line of, and is located within the spinal cord. When you see charts of the chakras, it is hard to miss that they stack one on top of the other along the central line of the body. In yogic and vedic practice, the focus is on opening all the 7 main chakras, allowing energy to flow unobstructed through the central channel, a state called “Nirvana” or enlightenment.
The lower chakras are considered to be more earth-bound, while the upper ones are more connected to the ethereal. As we look at the properties of each, the logic of this becomes evident.
We’ll start with the Root chakra, Muladhara. It is located at the base of the spine and the perineum, and is our physical and energetic foundation. Due to its position and controlling aspects of the legs and seat, it is considered the grounding connection to earth. It is said to enable confidence and trust, vitality and security, when in good health. In yogic charts, it is associated with the color red, and is involved with excretion and sexual function. It is here at the root chakra that Kundalini energy rests, the instinctual, libidinal energy that is typically represented as a coiled snake.
On the physiological side, the Coccygeal Plexus is located here, between the L4 vertebra and the coccyx. This nerve bundle supplies most of the legs, the pelvic floor and parts of the sexual organs. The sciatic nerve, emerging from L4 to S3, is the longest nerve in the body, along with its branches providing sensory information and motor control to the feet, legs and hips. This nerve is a primary source of information from the ground to the brain.
There is no commonly accepted endocrine structure in the area of the root chakra, although there are those who believe that the coccygeal body, a collection of blood vessels at the base of the spine, could be an endocrine gland. It physically resembles a gland, but as yet, there is no known hormone that it produces. Some claim the adrenals are associated with the root chakra, due to its connection with the “fight or flight” response to danger.
The second chakra is called Svadistana, or “Place of Joy”, shown in orange. Located directly in front of the sacrum, it is associated with sensuality, creativity and joy. In women, this chakra is at the physical location of the womb, the origin of new life. In men, it is in proximity to the prostate, where seminal fluid is produced and stored. The reproductive glands of both sexes are found in the sacral region. The egg and sperm are produced here, as are the hormones estrogen and progesterone in women, and testosterone in men, hormones critical for the process of renewed life.
This second chakra is found at the lumbar spine, between L1 and L4, the location of the lumbar nerve plexus. Muscles of the abdomen and hip flexors, the thighs and the sexual organs are innervated from the lumbar plexus, as is the large intestine. Much of this nerve bundle is embedded in or on the surface of the psoas muscle, which has a big impact on the health of the entire lumbar region, including the internal and sex organs (see previous blog post on psoas for more details).
Manipura, or “City of Jewels” is the third chakra, represented by the color yellow. It is commonly known as the solar plexus, due to its location, just below the ribcage. It is the place of personal power, motivation and vulnerability. This chakra is considered the transition between the earthbound lower chakras and the more spiritual upper ones. The drive to “become something” is based here, a motivation unique to humans. It is also the source of personal opinion and “gut reactions”.
Physiologically, the celiac plexus, also known as the solar plexus, is at the same location as the third chakra, in front of the top of the lumbar spine. It is made up of a number of smaller plexii that innervate the digestive system. The digestive nerves are a mix of autonomic, and enteric (controlling the function of the intestines), both being outside the realm of conscious control; and somatic nerves from the lower thoracic region, supplying the abdominal muscles.
Breathing is an important, life sustaining function controlled by the diaphragm, located just above the solar plexus. It is unique in that it functions on both a conscious and unconscious level, bringing oxygen into the body and moving carbon dioxide out, at the same time massaging the organs of digestion. It can be strongly impacted by emotional stress and tensional forces on the ribcage and abdominal musculature, causing shortness of breath and restrictions to the metabolic process that supplies every cell of our bodies with energy.
The solar plexus innervates the pancreas and adrenals. The pancreas produces insulin and glucagon, the primary regulators of sugar levels in the blood stream, controlling the amount of energy available to the body. The adrenal glands, found on top of the kidneys, produce cortisol, epinephrine and norepinephrine, stress hormones. These chemicals are released into the blood to produce a rapid increase in blood sugar, allowing the body to respond quickly to perceived threats.
The heart chakra is fourth on the list, shown in green, and located at the heart. In Sanskrit, it is called Anahata, or “Unstruck Sound”. As with many cultures, yogic tradition associates the heart with love, compassion, relationship and empathy. It is at the heart that we begin to consider the needs of others, and the impact of our actions outside ourselves. Hugging brings a loved one physically close to the heart. Conversely, loneliness, anger, sorrow and grief are felt here.
Protected inside the ribcage, the heart is relatively safe from outside physical threats. Being the place where our interactions with others are negotiated, however, it is easy to see how a person might feel the need to protect from emotional insecurities. This often plays out in the musculature around the ribcage. The intercostals, muscles between the ribs that assist in breathing, can become stuck in contraction, limiting the ability of the lungs to function fully. The pectorals, which lay over the front of this region, can become shortened, causing the shoulders to roll forward, giving the appearance of a hollowing of the chest.
The cardiac plexus supplies the heart with significant information about the physical as well as the emotional state of the body as a whole. Made up of sympathetic and parasympathetic fibers, the cardiac plexus provides information relating to unconscious feelings. Nerves of the upper thoracic spine are part of the plexus as well, innervating the intercostal muscles and skin over the ribcage. Recent studies using biofeedback have shown that the heartbeat responds instantaneously to thoughts, emotions and activities. The heart also has its own electrical generator, the sinoatrial node, which creates and maintains the heartbeat that we are all familiar with.
The thymus is the endocrine gland associated with the heart chakra. It is responsible for healthy development of the immune system in children. It shrinks as we mature, but still plays an important function in determining what are foreign elements within the body, whether they are harmful or not, and whether or not they need to be removed. When the heart chakra is closed, the immune system is likely compromised.
Next up in the series is the throat chakra, called Visuddha. Located at the base of the throat, it is shown as blue. It affects the throat, shoulders and arms and is said to be involved with expression, communication, purification and discernment. Here is where we express to the outside world what is going on internally. Through vocalization and physical contact, writing and other forms of communication, we are able to let others understand what we are feeling and thinking. It is also at the 5th chakra where all signals and emotions arising from the lower chakras are filtered before being received by the conscious mind.
There are two important nerve plexii associated with the 5th chakra. They are within the region of the cervical spine, between C1 and T1. The first is the cervical plexus, which innervates the muscles and skin of the neck. The second, the brachial plexus provides for the entire upper extremity, including shoulders, arms and hands. The nerves that provide the lungs and upper abdominals generate from here, as do some of the cranial nerves that control speech and motor abilities for the mouth and throat.
Cases where this chakra is restricted may be related to the person feeling the need to hold in their emotions. A muscular pattern, similar to the fear response where the head comes down and forward, chin out, and shoulders elevated and often rounded forward, can become a chronic postural issue, causing back and neck pain, issues with the shoulders and arms, and physically constricting the airway and voice.
The thyroid, located just below the Adams apple in front of the throat is the endocrine gland associated with the throat chakra. The thyroid gland is controlled by the pituitary, and produces hormones that strongly affect the body’s energy level. It also works in conjunction with the parathyroid to balance calcium levels throughout the body.
The third eye, Ajna, is located between the eyebrows in the center of the forehead. This 6th chakra, represented by the color indigo, is considered the psychic center, involved with perception, imagination, insight and dreaming. A manifestation of the brain, it is the control center for the mind/ body. The main goal of yoga is to clear blockages of the lower 5 chakras, allowing awareness of mind-driven conscious and body-driven unconscious impulses to be fully realized in the third eye. In this way, the individual can become more consciously aware of the body, and is much better able to make effective decisions about how to proceed through life.
Imbalances of the 6th chakra occur with either regular overstimulation of the 5 senses or overstimulation of the intellectual mind. In our present western society, where computers, gaming and other mind-based pursuits far exceed more physically balanced ones in their esteem and popularity, it is no surprise that we have increasing incidences of ADHD, insomnia and an inability to concentrate.
The nervous system component of the 6th chakra is the brain, the most electrically charged region of the body. The brain is the traffic cop for the entire body, involved with thinking, memory, motor control, spatial perception, the five senses, as well as the unconscious systems like breathing, blood circulation, body temperature and so on. As the brain is to the physical body, so the 6th chakra is to the energy body.
And as the brain is to the physical body, so the pituitary gland is to the endocrine system. Its primary function is to manufacture and distribute broad-reaching regulating hormones that affect the entire body. It produces growth hormone, essential for growth and repair of tissue; prolactin, the activator for milk production; oxytocin, an important hormone for maternal behaviors such as bonding, breast-feeding and birthing; endorphins, the happy drugs released during exercise, excitement and orgasm; a hormone that stimuates the adrenal cortex during times of stress; thyroid stimulating hormone, and several others.
The hypothalamus links the pituitary to the central nervous system, acting as orchestra master and gatekeeper. Receiving its signals directly from the brain, it sends nerve impulses to the pituitary signaling the need to produce the hormones the body needs.
Last, but certainly not least, the seventh chakra is known as the Crown chakra, or Sahasrara in Sanskrit, located at the crown of the head. It is represented by one of several different colors; either violet, gold or white, with the symbol of a multi-petaled lotus flower. The crown chakra extends beyond the physical body, a globe of colored light, transcending the material universe. Those who subscribe to the idea of a god see this as the connection to the divine. In yogic tradition, there is a concept called “Samadhi”, which is the union between the consciousness of the experiencer and that of the experienced. When the practitioner feels himself one with the universe, leaving his attachment to “self” behind, he has reached an enlightened state.
Being the connection to higher consciousness, this chakra does not have the same correlations to physical properties of the body. There is no muscular or nervous association, and there is disagreement about an endocrine connection, which has some very interesting points.
Depending on the source, the pineal gland is grouped with either the 6th or 7th chakra. This gland is commonly known as the Third Eye. It is about the size of a grain of rice, and is located near the center of the brain. It is the only structure of the brain that is one-sided, leading 17th Century French scientist and philosopher Rene Descartes to consider it the “seat of the soul”, the place where the body and soul meet, and where signals from two eyes, two ears and two hemispheres of the brain become one. Ancient cultures in Egypt and elsewhere believed the third eye was the doorway to the subconscious, or unconscious mind, leading to paranormal powers, astral travel, etc.
The pineal gland in humans has photoreceptors and some of the structures of an eye, although it is deep within the skull. There are examples of animals, including some types of frogs, lamprey eels and certain reptiles that have a pineal foramen (opening in the skull) and what is known as a “parietal organ”, an actual third eye.
The primary known function of the pineal gland is the production of melatonin, a chemical that regulates circadian rhythms, particularly the 24-hour cycle of awake and sleep time. It is most active at night, as it is sensitive to light. Melatonin has also been associated with depression and low energy during long periods of overcast skies and short days of winter.
Those who associate this gland with the 6th chakra consider the third eye to be between the eyebrows. The crown chakra believers see it as accessed through a vortex from above the head, leading down to a fulcrum at the pineal gland.
I hope that those of you who managed to read through this “brief” synopsis have come away with a better understanding about, and possibly more affinity for this interesting system of organization of bodily function. For me personally, I have learned so much that writing it was a worthwhile endeavor all on its own. I am confident that the link between the physical and energetic connection that I already experience regularly when doing massage, as well as yoga, will be greatly enhanced by a clearer idea of what I am affecting, or trying to affect.
