What then is the way in which one can be sure to have the mind focused upon good things, and so to receive only good impressions? There are three considerations.

First, one must be able to keep all the ever-moving thoughts away which come into one's mind. One must develop that mental strength, that will-power which will keep all thoughts away which come into one's mind during concentration and take one's mind away from the object on which one focuses it.
Secondly, the mind will always focus itself upon the object which it loves. If one does not have love for the divine Being, for God, if one does not have that ideal, then it will certainly be difficult, for it cannot be done by the intellect. The person who only uses his intellect keeps asking, "Where shall I direct my mind, on what object shall I focus it? Please, picture it for me, and point out where it is." It is the lover of God whose mind cannot wander anywhither, save always directly to God.
Then, purity of mind is necessary. The mind must be pure from all fear, worry and anxiety, and from every kind of falsehood, for all this covers the mind from the vision of God. When the mind, full of faith, love, purity and strength, is focused upon the ideal of God, man will receive teaching, inspiration and advice directly and for every case he meets with in life.
