Our minds are forced to become fixed upon different things by an attraction in them which we cannot resist. To control the mind, to place it just where we want it, requires special training. It cannot be done in any other way. In the study of religion the control of the mind is absolutely necessary. We have to turn the mind back upon itself in this study.
Swami VivekanandaThere is no limit to the power of the human mind. The more concentrated it is, the more power is brought to bear on one point
