What is Yoga?
Developed in India, Yoga is a psycho-physical discipline with roots going back about 5,000 years. Today, most Yoga practices in the West focuses on the physical postures called "asanas," breathing exercises called "pranayama," and meditation. However, there's more to it than that, and the deeper you go the richer and more diverse the tradition becomes. The word "Yoga" means union. Linguistically, it is related to the Old English "yoke." Traditionally, the goal of Yoga is union with the Absolute, known as Brahman, or with Atman, the true self. These days the focus is often on the more down-to-earth benefits of Yoga, including improved physical fitness, mental clarity, greater self-understanding, stress control and general well-being. Spirituality, however, is a strong underlying theme to most practices. The beauty of Yoga is in its versatility, allowing practitioners to focus on the physical, psychological or spiritual, or a combination of all three.
How many times a week should I do Yoga and for how long?
Most schools teach a practice session that lasts 60-90 minutes. If you can do that everyday -- great. If not, try and do that much a few days a week, including a class or two, and fill in with shorter sessions on days when you don't have as much time. Any Yoga is better than no Yoga, and 20 to 30 minutes a day is better than 90 minutes once a week.
