What does yoga do for the person!

I think there are many variety of yoga system. As far as I know, yoga mainly deals with physical, the channel or channel of what say the an energy and then also the different nerve centers. So it is too some kind of control or some kind of change on the physical level, that effect on the mind. So it is both. Another one, which is just simply through the training of mind, just simply try to utilize the mental force and then change the body's mental level.

Here, you know, I don't like external things. In emotional level or mental level, there are contradictory sort of forces or thoughts there. So in order to reduce another one, all this logically, the opposite side, if you increase, then the other side will minimize. So that's the way.

Now, for example, anger. If we have some kind of realization and there is something bad for the community, so one's own peace of mind, then, you see, try too find what the opposite sort of emotion. That's love and kindness or compassion. So once we realize that, try to increase these opposite power or force. That's the system, the training of mind.
