Written and published in 1901 by "Sir William" (pseudonym), The Occults in Service or, The Great Learning, was intended to be the first volume in a series, but that was not to be. Only this work: Volume One, was ever publshed (privately).The author claims to have intimate knowledge concerning the immortality of mankind which has been witheld from man for ages. Without knowledge of the infnite, man becomes finite - a mere animal, consumed by self preservation and materialism. To know of infinite life is to know the immortal world. It is the author's stated desire to reveal and communicate the infinite truths of the immortality of mankind, the facts of creation, occult philosophy etc., hidden behind a veil of secrecy for so long.Accompanying this knowledge are claims of interplanetary communication/visitation with evidence presented of correspondence between "The Occult King" and the King of Mars. As well, the significance of the Queen of Sirius' royal visit to the planet Mars is documented. Closer to home, life in Wieland, North Pole and the South Pole country - habitated by the Pullians, is described in detail.
