Body - Mind - Heart - Spirit
If you’re a typical health-conscious Yoga International reader, you've probably already exercised today. Whether you went for a brisk walk, played some tennis, or worked out at the gym, you recognize the importance of keeping your physical body in shape. But have you exercised your subtle body yet? Or your causal body? According to the yoga tradition, every one of us has five bodies, each made of increasingly finer grades of energy. And if we intend to live a fully balanced, healthy life, it tells us, all our bodies need to be kept in good condition.
The five progressively subtler bodies that compose our personality are described in a yoga classic called the Taittiriya Upanishad:
“Human beings consist of a material body built from the food they eat. Those who care for this body are nourished by the universe itself.
“Inside this is another body made of life energy. It fills the physical body and takes its shape. Those who treat this vital force as divine experience excellent health and longevity because this energy is the source of physical life.
“Within the vital force is yet another body, this one made of thought energy. It fills the two denser bodies and has the same shape. Those who understand and control the mental body are no longer afflicted by fear.
“Deeper still lies another body comprised of intellect. It permeates the three denser bodies and assumes the same form. Those who establish their awareness here free themselves from unhealthy thoughts and actions, and develop the self-control necessary to achieve their goals.
“Hidden inside it is yet a subtler body, composed of pure joy. It pervades the other bodies and shares the same shape. It is experienced as happiness, delight, and bliss.”
These five bodies are called koshas, or “sheaths,” in Sanskrit, because each fits in the next like a sword in a scabbard. Only the densest is made of matter as we know it; the other four are energy states invisible to the physical eye, though we can easily sense their presence inside us when we pay close attention. Since the inner bodies are the source of our well-being during life and are the vehicles we travel in after death, India’s ancient yogis developed specific exercises to strengthen and tone each one in turn.
You’re already familiar with your physical body. It’s called annamaya kosha in yoga, (maya means “made of” and anna means “food” or “physical matter.”) But yoga also makes you aware of a second body, the organizing field that holds your material body together. This is the life energy that governs your biological processes, from breathing to digestion to the circulation of your blood. It’s called chi in Chinese medicine and prana in yoga. The ancient Egyptians called it the ka.
Acupuncture and homeopathy don’t directly affect your physical body; they work on the vital force that activates and sustains it. Orthodox physicians in the West recognized the importance of the vital force up till the 19th century, but with the development of sulfa drugs and antibiotics, their attention shifted from the energy states underlying human biology to focus exclusively on the physical body itself.
The energy body is called the prana-maya kosha in yoga. When it ceases to function your physical body can no longer operate. Your heart and lungs stop working and your cells begin to disintegrate. In Western culture we strongly identify with our material body, yet without prana supporting and directing it, it can’t survive more than a few minutes.
Yoga devotes an entire class of practices called pranayama to replenishing
the vitality of the pranamaya kosha. Exercises like diaphragmatic breathing, the complete yogic breath, and alternate nostril breathing are specifically designed to enhance the proper functioning of your second sheath.
In addition, getting plenty of fresh air and sunlight is essential for maintaining the health of the vital force. Yoga texts explain that the sun is the ultimate source of prana, and it is said that some advanced yogis go for years without eating; instead they simply absorb the prana radiated by the sun. For most of us, however, fresh whole foods are a major source of prana.
The third sheath or mental body is the apparatus responsible for our sensory and motor activities and our day-to-day awareness when we’re functioning “on automatic.” It processes input from our five senses and responds reflexively. When we move through life passively, reacting to our environment rather than actively shaping it, our awareness is focused here. Many people, and most animals, routinely operate at this level.
This body is called manomaya kosha (which means “body made of thought processes”). In the West we associate our routine mental state with the brain, but according to yoga the entire nervous system (including the brain) merely mediates the activity of the manomaya kosha, expressing the commands of this higher energy state through the physical body.
You get a clear sense of what the mental body is when you observe a patient in a coma. Their second sheath is still operating so their heart continues to pump and their lungs expand and contract. But the person has no awareness of the external world and no ability to take action because the activity of the mental body has shut down. The pranamaya kohsa operates from the moment of our first breath to our last, but the manomaya kosha shuts down temporarily on a daily basis, regenerating itself during the state of deep sleep.
The health of the manomaya kosha is tremendously enhanced through the practice of mantra meditation. This soothes and balances this inner body, and helps release “knots” of energy tied up in mental complexes and obsessive thoughts. Yogis who spend a great deal of time in meditation often have very little need for sleep, in part because their mental vehicles are functioning optimally, like a car that’s just had a tune-up.
The mental body “feeds” on the sense impressions we offer it. If we supply our third sheath with a continual stream of violent TV shows and video games, for example, it begins to crave increasingly aggressive forms of stimulation, and may become more agitated and less sensitive to the suffering of others. If we “stuff” it with too much work or too much play we may experience a form of mental “indigestion,” leaving us feeling harried or exhausted. A harmonious environment, interesting professional challenges, and fun and supportive relationships offer an ideal diet for the mind. A daily session of pratyahara, or sensory withdrawal, leading into meditation provides an excellent inner tune-up.
Subtler still is the vijnanamaya kosha (vijnana means “the power of judgment or discernment”). It’s often translated as “intellect,” but the real meaning is broader, encompassing all the functions of the higher mind, including conscience and will. It may be easier to understand the distinction between the third sheath or mental body and the fourth sheath or intellectual body by taking a look at those in whom the vijnanamaya kosha is underdeveloped.
One such type is someone who doesn’t seem to be in control of her life, who is constantly reacting to circumstances rather than making a decision and responding proactively. This kind of woman has a hard time making up her mind, thinking for herself, or being creative. She has very little willpower and is continually the victim of her own poor judgment.
Another example of a deficient fourth sheath is someone without strong personal ethics. He may attend religious services and speak piously about moral values, but when the opportunity arises to benefit himself at the expense of others, he doesn’t hesitate to act. His ability to discern between right and wrong is weak; conscience is a platitude rather than a living experience for him.
An activated fourth sheath is what distinguishes human beings from animals. Only humans have the ability to direct their own lives, free from the promptings of instinct, and to make moral choices. The sages considered the development of a healthy vijnanamaya kosha so important that they placed the exercises for it at the very beginning of the yoga system. These are the yamas and niyamas, commitments every yoga student is asked to make: not to harm, lie, steal, overindulge, or desire more than you actually need; instead you are asked to be content, pure, self-disciplined, studious, and devoted.
Jnana yoga also works with this kosha. This is the path of the intellect in which you are advised to study spiritual truths, contemplate them deeply, and finally incorporate them into the very core of your personality. On this path your spiritual understanding becomes the “food” with which you nourish your intellect.
As your meditation practice deepens over the months and years, your ability to connect with inner guidance is enhanced. You begin to experience the events in your life, even the painful ones, in a calm and objective manner. Your yogic lifestyle, contemplation, and meditation lead to clarity of judgment, greater intuitive insight, and increased willpower as your vijnanamaya kosha grows stronger and more balanced.
In the vast majority of humans, the fifth sheath is totally underdeveloped. This is the anandamaya kosha, the subtlemost body which is experienced as ananda (spiritual bliss). Generally only saints, sages, and genuine mystics have done the inner work necessary to make ananda a living part of their daily experience, and most people are hardly even aware that this level of consciousness exists within themselves.
The anandamaya kosha is extremely important in yoga because it’s the final and thinnest veil standing between our ordinary awareness and our higher Self. Many individuals who’ve had near-death experiences have reported experiencing a brilliant white light radiating all-embracing wisdom and unconditional love. This is the experience of the anandamaya kosha. Saints and mystics purify their minds so that they can have this experience throughout life, not just for a fleeting moment at death.
In the tantric tradition, spirit is often symbolized as Shiva, the transcendent Lord who is ever immersed in divine consciousness. Matter/energy is called Shakti, the Supreme Goddess whose divine body is this entire universe. It’s said that they love each other with unspeakable intensity. Their supreme love is experienced in the anandamaya kosha, where spirit and matter passionately embrace.
We can awaken our bliss sheath through three practices. The first is seva, selfless service. This opens our heart to our innate unity with other beings. The second is bhakti yoga, devotion to God. This opens our heart to our unity with the all-pervading Divine Being. The third is samadhi, intensely focused meditation, which opens our heart to our own divine being.
You are a multidimensional creature. Your awareness manifests on many different planes. Yoga introduces you to yourself and trains you to live fully and gracefully at every level of your being. From the hatha postures that strengthen and tone your physical body to the breathing exercises that balance and vitalize your life force, from the meditation practice that quiets and clears your mind to the self-study and selfless love that open up an inner world of knowledge and unity, yoga is a holistic system that develops and integrates every part of your personality. By getting to know your five bodies and the inner Self (whose awareness illumines them all), you can experience the health and fulfillment of an enlightened life.
The five sheaths are not theoretical constructs. They are real parts of your being that you can actually experience. The following eight-step exercise will help you get a fuller sense of these inner dimensions of your personality.
In many yoga texts you’ll find the five sheaths grouped into three. The physical body and vital force are called the sthula sharira, the “gross body.” The mental body and intellect are called the sukshma sharira, the “subtle” or “astral body.” The bliss sheath is called the karana sharira, the “causal body.” These are recognized in many different spiritual traditions. Plutarch, a Greek priest who presided at the Temple of Delphi in the first century ce, called them the soma, psyche, and nous, respectively.
The gross body disintegrates at death. The subtle body disintegrates at rebirth, allowing you to develop a new personality in your next life. The causal body reincarnates again and again, carrying your karma with it like luggage. It finally disintegrates at the time of liberation, when the higher Self disengages from the cycle of birth and death.
