gence, or the spiritual world. People ia general look only at the visible world, which is called also the present world, the sensible world and the material world; their knowledge of it also is trivial and limited. And there is also a window in the heart from whence it surveys the intelligible world. There are two arguments to prove that there are such windows in the heart. One of the arguments is derived from dreams. When an individual goes to sleep, these windows remain open and the individual is able to perceive events which will befall him from the invisible world or from the hidden table of decrees, and the result corresponds exactly with the vision. Or he sees a similitude, and those who are skilled in the science of interpretation of dreams understand the meaning. But the explanation of this science of interpretation would be too long for this treatise. The heart resembles a pure mirror, you must know, in this particular, that when a man falls asleep, when his senses are closed, and when the heart, free and pure from blameable affections, is confronted with the preserved tablet, then the tablet reflects upon the heart the real states and hidden forms inscribed upon it. In that state the heart sees most wonderful forms and combinations. But when the heart is not free from impurity, or when, on waking, it busies itself with things of sense, the side towards the tablet will be obscured, and it can view nothing.
