What is commonly referred to as "yoga" can be more accurately described by the Sanskrit word asana, which refers to the practice of physical postures or poses.
Asana is only one of the eight "limbs" of yoga, the majority of which are more concerned with mental and spiritual well-being than physical activity. In the West, however, the words asana and yoga are often used interchangeably.
Yoga PosesMany 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 thealignment of the pose. The poses are a constant, but the approach to them varies depending on the tradition in which the teacher has trained.
Yoga PracticeYoga 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, playing of singing bowls, and/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.
