I am using all these words because they are in usage in today's world. People say “recreational Yoga,” health Yoga,” people refer to it as an art form - they think they are doing a service to Yoga by saying it is an art form. No. The moment you attach the word “Yoga,” it indicates it is a complete path by itself. The word Yoga” essentially means, “that which brings you to reality”. Literally, it means union. Union means it brings you to the ultimate reality, where individual manifestations of life are surface bubbles in the process of creation. Right now, a coconut tree and a mango tree have popped up from the same earth. From the same earth, the human body and so many creatures have popped up. It is all the same earth. Yoga means to move towards an experiential reality where one knows the ultimate nature of the existence, the way it is made. Yoga refers to union not as an idea, a philosophy or as a concept that you imbibe. As an intellectual idea, if you vouch by the commonness of the universe, it may make you popular in a tea party, it may give you a certain social status, but it does not serve any other purpose. You will see, when things come down to even money - it does not even have to boil down to life and death - even for money, “This is me, that is you.” The boundary is clear; there is no question of you and me being one.
