"Anxiously following their precepts--the truth of which soon appeared--I found that solitude, fast, intense reverie upon the one theme on which we desired knowledge, were the true elements and purifiers of this glorious faculty. It was by these means, and by this power, that men so far behind us in lesser lore achieved, on the mooned plains of Chaldea and by the dark waters of Egypt, their penetration into the womb of Event;--by these means, and this power, the solitaries of the Gothic time not only attained to the most intricate arcana of the stars, but to the empire of the spirits about, above, and beneath the earth; a power, indeed, disputed by the presumptuous sophists of the present time, but of which their writings yet contain ample proof. Nay, by the constant feeding, and impressing and moulding, and refining, and heightening, the imaginative power, I do conceive that even the false prophets and the evil practitioners of the blacker cabala clomb into the power seemingly inconceivable--the power of accomplishing miracles and prodigies, and to appearance belie, but in truth verify, the course of nature. By this spirit within the flesh, we grow _from_ the flesh, and may see, and at length invoke, the souls of the dead, and receive warnings, and hear omens, and girdle our sleep with dreams. "Not unto me," continued the cabalist, in a lowlier tone, "have been vouchsafed all these gifts; for I began the art when the first fire of youth was dim within me; and it was therefore with duller and already earth-clogged pinions that I sought to rise. Something, however, I have won as a recompense for austere abstinence and much labour; and this power over the land of dreams is at least within my command." "Then," said Lucilla, in a disappointed tone, "it is only by a long course of indulgence to the fervour of the imagination, and not by spell or charm, that one can gain a similar power?" "Not wholly so, my daughter," replied the mystic; "they who do so excite, and have so raised the diviner faculty, can alone possess the certain and invariable power over dreams, even without charms and talismans; but the most dull or idle may hope to do so with just confidence (though not certainty) by help of skill, and by directing the full force of their half-roused fancy towards the person or object they wish to see reflected in the glass of Sleep." "And what means should the uninitiated employ?" asked Lucilla, in a tone betokening her interest. "I will tell thee," answered the astrologer. "Thou must inscribe on a white parchment an image of the sun." "As how?" interrupted Lucilla.
