The difference between the chair thought and the table thought, the red thought and the green thought, the innumerable relationships among ideas, are all explicable by the fact that the mind's primary power is image making. This is a power which, in human beings, can be called into play deliberately and voluntarily, as we often do during wakefulness, or spontaneously and involuntarily, as we invariably do during dreams. The moment mind emerges from deep sleep and becomes active, it begins to imagine the wakeful world. What happens with men on a small scale happens also with the Universal Mind (God, if you like) on a cosmic scale. Its first activity is imagining.
