Creative Thought: This exercise makes use of one of man's most valuable powers--spiritualized imagination. Everyone possesses the image-making faculty to some degree and artists to an extraordinary degree. The student must strive to get something of the artist's imaginative capacity and then ally it with the illuminating and dynamizing power of his higher self. But this can only be successfully and perfectly achieved if, first, the images are harmonious with the divine will for him and if, second, he has developed to the second degree of meditation. But not many can fulfil these conditions. Nevertheless, all may attempt and benefit by the exercise, even though their attempt will be halting, their benefit partial, and the results imperfect. For even then it will be greatly worthwhile. This is the right way to make imagination serve him, instead of letting it evaporate in useless fantasies or harmful daydreams.
