The control of perceptions.

How does one practice self control, and hence practice the self control of how we perceive? One must feel as one is not, not in control of one's perceptions. For example, one must not feel while one is perceiving, that one is perceiving a perception too much, or too little, but that one is perceiving, just so. This is the easiest method of practicing self control. Perhaps, if we pay attention on our perceptions, we are carried away by our perceptions, hence, we must not get carried away by our perceptions.
