Yoga is about health, strength, vitality, relaxation and
peace of mind
Yoga provides effective ways to release tension and stress in the body and mind. In practice, one could say that yoga is a discipline which continues to deepen and further one's ability to answer the question 'what is yoga' appropriately. For the sincere yogi, the horizon of the question itself is continually widening, there is a gradual and expanding insight into its meaning.
Most people associate yoga predominantly with its asana tradition or yogic postures, one hears of 'yoga and meditation' as if the two are a separate practice. But of course they are not. Meditation is at the very heart of yoga. The physical postures or asanas are a yogic discipline for purifying body and mind. These postures strengthen the entire body, systematically stretching and toning muscles, ligaments, keeping spine and joints flexible, improving circulation, stimulating a healthy functioning of all internal organs and the entire nervous system.
