True yoga is not about the shape of your body, but the shape of your life. Yoga is not to be performed; yoga is to be lived. Yoga doesn’t care about what you have been; yoga cares about the person you are becoming. Yoga is designed for a vast and profound purpose, and for it to be truly called yoga, its essence must be embodied. Aadil Palkhivala
Yoga a brief history......
Yoga is an ancient practice with derives from India. Modern Yoga is based on the sage Patanjali's Yoga Sutras, which was collated over an estimated 2,000 years ago. The Yoga Sutras is a collection of statements that serves as a philosophical guidebook for most of the yoga that is practiced today. It also outlines eight limbs of yoga: the yamas (restraints), niyamas (observances), asana (postures), pranayama (breathing), pratyahara (withdrawal of senses), dharana (concentration), dhyani (meditation), and samadhi (absorption). As we explore these eight limbs, we begin by refining our behavior in the outer world, and then we focus inwardly until we reach samadhi (liberation, enlightenment).
Today most people practicing yoga are engaged in the third limb, asana, which is a range of physical postures designed to purify the body and provide the physical strength and stamina required for long periods of meditation.
