This document discusses the origins and evolution of yoga over centuries. It originated in ancient India with Lord Shiva, known as Adiyogi, teaching yoga to seven disciples. They then spread yoga teachings around the world. Yoga provides physical, mental and spiritual benefits through practices like asanas (poses), pranayama (breathing exercises), chanting "Aum", and focusing the eyes in different directions known as drishtis. The document is divided into two parts, with the second part detailing the nine types of drishtis or eye focuses used in yoga.
