Since Time and Space are the Conditions of Mind, these two Studies are fundamental. Yet there remaineth Causality, which is the Root of the Actions and Reactions of Nature. This also shalt thou seek ardently, that thou mayst comprehend the Variety of the Universe, its Harmony and its Beauty, with the Knowledge of that which compelleth it. Yet this is not equal to the former two in Power to reveal thee to thy Self; and its first Use is to instruct thee in the true Method of Advancement in Knowledge, which is fundamentally, the Observation of the Like and the Unlike. Also, it shall arouse in thee the Ecstasy of Wonder; and it shall bring thee to a proper Understanding of Art Magick. For our Magick is but one of the powers that lie within us undeveloped and unanalysed; and it is by the Method of Science that it must be made clear, and available to the Use of Man. Is not this a Gift beyond Price, the Fruit of a Tree not only of knowledge but of Life? For there is that in Man which is God, and there is that also which is Dust; and by our Magick we shall make these twain one Flesh, to the Obtaining of the Empery of the Universe.
