A little about yoga.

Yoga is both a means to Self-realization and the desired goal of man, which is the union of the individual "I" and the universal "I". The goal of yoga is one. The sole purpose is to remove the obstacles that prevent people from fully enjoying their lives. It is very easy to become a teacher. It takes a lifetime to become a student. The easiest thing in the world is to teach what you don't know and don't practice. The hardest thing to practice is what you teach.
