Yoga is not emotion. It is not stirring oneself into any kind of made-up or artificial individuality. Emotion is not possible where wisdom prevails. The mind has to be controlled. It has to be done intelligently.
Emotion has no part in it.
Everyone is a part of the vast creation. Even those who do not know what Yoga is, and do not practise it, and have no idea about it, are essentially intended for this great movement called Yoga, towards the goal that is the goal of everyone. Yoga is control of the mind, and mind is to be controlled because it is the principle of isolation in a false manner. It is the mind, it is the Chitta, it is the Antahkarana or the internal organ, that makes us falsely believe that we are individuals, with a physical independence of our own, isolated from the vast structure of creation. If one understands one's position and knows where one stands, he must also know what is the step that he has to take to place himself in the correct position under the system of the universe.
