Almost every one who has ever busied himself with such matters has come, in trance or dream, upon some new and strange symbol or event, which he has afterwards found in some work he had never read or heard of. Examples like this are as yet too little classified, too little analyzed, to convince the stranger, but some of them are proof enough for those they have happened to, proof that there is a memory of nature that reveals events and symbols of distant centuries. Mystics of many countries and many centuries have spoken of this memory; and the honest men and charlatans, who keep the magical traditions which will some day be studied as a part of folk-lore, base most that is of importance in their claims upon this memory.

 I have read of it in ‘Paracelsus’ and in some Indian book that describes the people of past days as still living within it, ‘Thinking the thought and doing the deed.’ And I have found it in the prophetic books of William Blake, who calls its images ‘the bright sculptures of Los’s Halls’; and says that all events, ‘all love stories,’ renew themselves from those images. It is perhaps well that so few believe in it, for if many did many would go out of parliaments and universities and libraries and run into the wilderness to so waste the body, and to so hush the unquiet mind that, still living, they might pass the doors the dead pass daily; for who among the wise would trouble himself with making laws or in writing history or in weighing the earth if the things of eternity seemed ready to hand?

—W.B. Yeats
