Here is an infographic poster about yoga and there are 8 mini-pictures illustrating yoga information. Yoga does not speak to union as an idea, a philosophy, or a notion to be absorbed. If you vouch for the commonness of the cosmos as an intellectual theory, it may make you popular at a tea party and give you a certain social status, but it serves no other purpose.

Individual expressions of life are surface bubbles in the process of creation, therefore union gets you to the ultimate reality. A coconut tree and a mango tree have both sprung from the same soil. The human body, as well as many other organisms, have arisen from the same ground. It's all there.
