Yoga, is a physical, mental, and spiritual practice or discipline which originated in ancient India. There is a broad variety of Yoga schools, practices, and goals in Hinduism, Buddhism, and Jainism. Among the most well-known types of yoga are Hatha yoga and Rāja yoga.
The origins of yoga have been speculated to date back to pre-Vedic Indian traditions, it is mentioned in the Rigveda, but most likely developed around the sixth and fifth centuries BCE, in ancient India’s ascetic and śramaṇa movements. The chronology of earliest texts describing yoga-practices is unclear, varyingly credited to Hindu Upanishads and Buddhist Pāli Canon, probably of third century BCE or later. The Yoga Sutras of Patanjali date from the first half of the 1st millennium CE, but only gained prominence in the West in the 20th century. Hatha yoga texts emerged around the 11th century with origins in tantra.
Yoga gurus from India later introduced yoga to the west, following the success of Swami Vivekananda in the late 19th and early 20th century. In the 1980s, yoga became popular as a system of physical exercise across the Western world. Yoga in Indian traditions, however, is more than physical exercise, it has a meditative and spiritual core.
One of the six major orthodox schools of Hinduism is also called Yoga, which has its own epistemology and metaphysics, and is closely related to Hindu Samkhya philosophy.
As yoga becomes increasingly diffuse and diverse, a single, common definition that can be agreed upon by everyone is almost impossible.
Complicating matters further, the term yoga has been in use for several thousand years and has shifted in meaning many times.
The word yoga comes from Sanskrit, an ancient Indian language. It is a derivation of the word yuj, which means yoking, as in a team of oxen. In contemporary practice, this is often interpreted as meaning union. Yoga is said to be for the purpose of uniting the mind, body, and spirit.
How can this union be achieved? Meditation is one way, but sometimes it is necessary to prepare the body for meditation by stretching and building strength. This is the physical practice of yoga, also know as asana.
Most modern yoga practices rely heavily on the Yoga Sutras of Patanjali, a series of aphorisms written c. 250 CE, as the basis for their philosophies. Patanjali classifies asana as one of the eight “limbs” of yoga, the majority of which are more concerned with mental and spiritual well-being than physical activity.
Many people think that yoga is just stretching. But while stretching is certainly involved, yoga is really about creating balance in the body through developing both strength and flexibility.
This is done through the performance of poses or postures, each of which has specific physical benefits. The poses can be done quickly in succession, creating heat in the body through movement (vinyasa-style yoga) or more slowly to increase stamina and perfect the alignment of the pose. The poses are a constant, but the approach to them varies depending on the yoga tradition in which the teacher has trained.
Yoga teachers will often refer to “your practice,” which means your individual experience with yoga as it develops over time. The amazing thing about yoga is that your practice is always evolving and changing, so it never gets boring. Although the poses themselves do not change, your relationship to them will. Anyone can start a yoga practice, even if you don’t feel like you are very flexible or very strong.
These things will improve the longer you practice. Another great thing about thinking about “your practice” is that it encourages the noncompetitive spirit of yoga. One of the most difficult, but ultimately most liberating things about yoga is letting go of the ego and accepting that no one is better than anyone else. Everyone is just doing their best on any given day.
In addition to practicing the poses, yoga classes may also include instruction on breathing, call and response chanting, meditation, or an inspirational reading by the teacher. The variety and amount of this will depend on the individual teacher and the yoga style in which he or she is trained.
Typically, a yoga class at a gym will be more focused on the purely physical benefits of yoga, while one at a yoga center may delve more into the spiritual side. Some people find that the physical practice of yoga becomes a gateway into a spiritual exploration, while others just enjoy a wonderful low-impact workout that makes them feel great. Whatever your tendency, you will be able to find a yoga class that suits your style.
Improved flexibility is one of the first and most obvious benefits of yoga. During your first class, you probably won’t be able to touch your toes, never mind do a backbend. But if you stick with it, you’ll notice a gradual loosening, and eventually, seemingly impossible poses will become possible. You’ll also probably notice that aches and pains start to disappear. That’s no coincidence. Tight hips can strain the knee joint due to improper alignment of the thigh and shinbones. Tight hamstrings can lead to a flattening of the lumbar spine, which can cause back pain.
And inflexibility in muscles and connective tissue, such as fascia and ligaments, can cause poor posture.
2. Muscle strength
Strong muscles do more than look good. They also protect us from conditions like arthritis and back pain, and help prevent falls in elderly people. And when you build strength through yoga, you balance it with flexibility. If you just went to the gym and lifted weights, you might build strength at the expense of flexibility.
3. Perfects your posture
Your head is like a bowling ball—big, round, and heavy. When it’s balanced directly over an erect spine, it takes much less work for your neck and back muscles to support it. Move it several inches forward, however, and you start to strain those muscles. Hold up that forward-leaning bowling ball for eight or 12 hours a day and it’s no wonder you’re tired. And fatigue might not be your only problem. Poor posture can cause back, neck, and other muscle and joint problems. As you slump, your body may compensate by flattening the normal inward curves in your neck and lower back. This can cause pain and degenerative arthritis of the spine.
4. Protects your spine
Spinal disks—the shock absorbers between the vertebrae that can herniate and compress nerves—crave movement. That’s the only way they get their nutrients. If you’ve got a well-balanced asana practice with plenty of backbends, forward bends, and twists, you’ll help keep your disks supple.
5. Bone health
It’s well documented that weight-bearing exercise strengthens bones and helps ward off osteoporosis. Many postures in yoga require that you lift your own weight. And some, like Downward- and Upward-Facing Dog, help strengthen the arm bones, which are particularly vulnerable to osteoporotic fractures.
6. Blood flow
Yoga gets your blood flowing. More specifically, the relaxation exercises you learn in yoga can help your circulation, especially in your hands and feet.
Yoga also gets more oxygen to your cells, which function better as a result. Twisting poses are thought to wring out venous blood from internal organs and allow oxygenated blood to flow in once the twist is released. Inverted poses, such as Headstand, Handstand, and Shoulderstand, encourage venous blood from the legs and pelvis to flow back to the heart, where it can be pumped to the lungs to be freshly oxygenated.
This can help if you have swelling in your legs from heart or kidney problems. Yoga also boosts levels of hemoglobin and red blood cells, which carry oxygen to the tissues. And it thins the blood by making platelets less sticky and by cutting the level of clot-promoting proteins in the blood. This can lead to a decrease in heart attacks and strokes since blood clots are often the cause of these killers.
7. Drains your lymphs and boosts immunity
When you contract and stretch muscles, move organs around, and come in and out of yoga postures, you increase the drainage of lymph (a viscous fluid rich in immune cells). This helps the lymphatic system fight infection, destroy cancerous cells, and dispose of the toxic waste products of cellular functioning.
8. Heart rate
When you regularly get your heart rate into the aerobic range, you lower your risk of heart attack and can relieve depression. While not all yoga is aerobic, if you do it vigorously or take flow or Ashtanga classes, it can boost your heart rate into the aerobic range. But even yoga exercises that don’t get your heart rate up that high can improve cardiovascular conditioning. Studies have found that yoga practice lowers the resting heart rate, increases endurance, and can improve your maximum uptake of oxygen during exercise—all reflections of improved aerobic conditioning.
9. Regulates your adrenal glands
Yoga lowers cortisol levels. If that doesn’t sound like much, consider this. Normally, the adrenal glands secrete cortisol in response to an acute crisis, which temporarily boosts immune function. If your cortisol levels stay high even after the crisis, they can compromise the immune system.
Temporary boosts of cortisol help with long-term memory, but chronically high levels undermine memory and may lead to permanent changes in the brain. Additionally, excessive cortisol has been linked with major depression, osteoporosis (it extracts calcium and other minerals from bones and interferes with the laying down of new bone), high blood pressure, and insulin resistance. In rats, high cortisol levels lead to what researchers call “food-seeking behavior” (the kind that drives you to eat when you’re upset, angry, or stressed). The body takes those extra calories and distributes them as fat in the abdomen, contributing to weight gain and the risk of diabetes and heart attack.
10. Releases tension in your limbs
Do you ever notice yourself holding the telephone or a steering wheel with a death grip or scrunching your face when staring at a computer screen? These unconscious habits can lead to chronic tension, muscle fatigue, and soreness in the wrists, arms, shoulders, neck, and face, which can increase stress and worsen your mood.
As you practice yoga, you begin to notice where you hold tension: It might be in your tongue, your eyes, or the muscles of your face and neck. If you simply tune in, you may be able to release some tension in the tongue and eyes. With bigger muscles like the quadriceps, trapezius, and buttocks, it may take years of practice to learn how to relax them.
11. Boosts your immune system functionality
Asana and pranayama probably improve immune function, but, so far, meditation has the strongest scientific support in this area. It appears to have a beneficial effect on the functioning of the immune system, boosting it when needed (for example, raising antibody levels in response to a vaccine) and lowering it when needed (for instance, mitigating an inappropriately aggressive immune function in an autoimmune disease like psoriasis).
12. Eases your pain
Yoga can ease your pain. According to several studies, asana, meditation, or a combination of the two, reduced pain in people with arthritis, back pain, fibromyalgia, carpal tunnel syndrome, and other chronic conditions. When you relieve your pain, your mood improves, you’re more inclined to be active, and you don’t need as much medication.
Yoga was used to unite the body, mind, and spirit. Often, people think of yoga as physical exercise. However, the progress of learning to still the mind and unify con-sciousness is also important in *yoga exercises. It can be dif-ficult to turn off the voices in your head, especially when your body is motionless.
Hatha is a Sanskrit word meaning “willful” and *yoga is translated as “union” or “communion.” This is understood as meditation in action. Hatha *yoga is a term familiar to many who practice *yoga, but it is not actually a particular style of *yoga.
There are many different styles of *yoga to choose from. Some are softer and easier to do, and some are strenuous and hard to do. If you are a beginner, it is probably best to try the easier forms, and it is necessary to work with a teacher. The following are a few approaches to choose from:
• Ananda *yoga will appeal to the beginner who desires to cultivate spirituality and learn how to meditate. Ananda is a slower-paced style.
• Ashtanga *yoga becomes more strenuous as the student progresses. The postures are linked together in a continuous flow,performed while practicing ujjayi breathing. A breath technique employed in a variety of Hindu and Taoistyoga practices. This builds stamina, strength, and flexibility. It is challenging, and not for the beginner.
• Bikram yoxa is also not for the beginner.
It requires a great deal of work. It is a sequential series of twenty-six postures done in a continuous flow. The room this practice is done in is heated to 100 degrees or more to promote sweating that helps cleanse the body of toxins.
• Kundalini and tantra *yoga focus on activating the energy centers in the body called chakras. The chakras are seven cores of energy in the body. This type of *yoga involves exploring the core of the body rather than the limbs moving to the center and seeing the body as rivers of energy.
• Raja *yoga concentrates more on meditation and less on strength and is good for the beginner.
• Sivananda *yoga is a holistic approach. There are five basic principles that unite the body, mind (intellect), spirit, and heart. They include proper breathing (pranayama), a vegetarian diet, proper relaxation (savasana), study of the Vedic scriptures, and meditation.
• Tivamukti *yoga focuses on spiritual teachings, postures, chanting, meditation, music, and readings, and are all incorporated into the class.
• There are many other types of *yoga, including kripalu *yoga, integral *yoga, and phoenix rising *yoga therapy. There are many unique techniques and teaching methods. The goals, however, are the same: to teach a greater understanding and awareness of the body; to free oneself from negative thoughts that drain one’s energies; and to strengthen mental and spiritual balance. Yoga postures remove obstructions from the body to enhance energy and well-being and achieve inner peace.
