There is another use of the imagination which is very valuable. If you will imagine in your thought-body the presence of the qualities that you desire to have, and the absence of those which you desire not to have, you are half-way to having and not having them. Also, many of the troubles of your life might be weakened if you would imagine them on right lines before you have to go through them. Why do you wait helplessly until you meet them in the physical world. If you thought of your coming trouble in the morning, and thought of yourself as acting perfectly in the midst of it (you should never scruple to imagine yourself perfect), when the thing turned up in the day, it would have lost its power, and you would no longer feel the sting to the same extent. Now each of you must have in your life something that troubles you. Think of yourself as facing that trouble and not minding it, and when it comes, you will be what you have been thinking. You might get rid of half your troubles and your faults, if you would deal with them through your imagination. As the thought body, becomes purified in this way, you must turn to the astral body. The astral body is purified by right desire. Desire nobly, and the astral body will evolve the organs of good desires instead of the organs of evil ones. The secret of all progress is to think and desire the highest, never dwelling on the fault, the weakness, the error, but always on the perfected power, and slowly in that way you will be able to build up perfection in yourself. Think and desire, then, in order to purify the thought body and the astral body.
