What is Yoga?

Yoga is a meditational practice involving the mind and body. It originated in India nearly 5000 years ago and has a mention in ancient Indian works. There are numerous styles or asanas of yoga combining physical poses, breathing techniques and meditation or concentration.

In recent years, yoga has gained tremendous popularity all over the globe. It is a form of physical exercise that promotes health along with balance and control of mind. Yoga has found immense support among the younger as well as older generations. Especially the older adults, who are unable of doing rigorous exercises, yoga is a boon for maintaining good health.

“Yoga Sutra,” a 2000-year old anthology on yoga and its philosophy by the Indian sage Patanjali is the ultimate guidebook to master the mind and control the body. This book is the oldest available text on yoga and is the foundation of all forms of modern yoga too.

Yoga was originally used for gaining spirituality and quieting the mind. Fitness was not the primary goal of yoga. Yoga as an exercise technique gained popularity in the 1920s and 1930s. This movement first began in India and slowly spread worldwide.
