Sadhguru says, yoga essentially means finding the keys to the nature of the existence.
Yoga is not about bending and twisting your body or holding your breath. It is a mechanism and a technology to get you to that state of experience where you see reality just the way it is.
Everything Becomes One
Is such a thing possible? The individual experience of who you are has its basis on the boundaries of your sensation. Whatever is within these boundaries is you, and whatever is outside is not you – this is your experience of life. For example, once you drink a glass of water, you experience the water as you. Everything that makes up your body right now was somewhere outside as food or water. Once you put this into the boundaries of your sensation, you experience it as “myself.”
At any moment in your life, if you have known an extreme sense of joy or ecstasy, if you had placed your hands about eight or nine inches over your body, you would have felt the sensation of touching the body. Similarly, it is a medical fact that even when a physical leg is amputated, the sensory leg is still intact.
The sensory body has its own presence beyond the physical body. There is a way to enlarge your sensory body.
If you make your life energies very exuberant and ecstatic, your sensory body becomes as large as you want it. Yoga is to expand the boundary of your sensation in such a way that you experience the whole universe as a part of yourself. Everything becomes one. That is union.
