Illumination is the Light of Wisdom, whereby a man perceiveth heavenly secrets.
"Which Light is the Spirit of God within the man, showing unto him the things of God."
ILLUMINATION (PART I) No. II.
London, John M. Watkins
Second Edition Edited by Samuel Hopgood Hart 
To the numerous and world-wide circle of genuine students of Divine things, who recognised in Anna Kingsford a Seer, an Interpreter, and a Prophet of the rarest lucidity and inspiration, and a foremost herald of the dawning better age: and especially to the Friend whose instant and enthusiastic appreciation proved an invaluable support in a position of peculiar difficulty, and beneath whose roof some of the illuminations herein contained were received, but who desires to remain unnamed: and also to the "friend, disciple, and literary heir of the renowned magian, the late Abbé Constant ("Eliphas Levi")"--namely, to the Baron Giuseppe Spedalieri, for manifold tokens of high approbation and devoted friendship-this book is affectionately inscribed.
"And I saw another angel flying in mid-heaven, having an eternal gospel to proclaim unto them that dwell on the earth, and unto every nation, and tribe, and tongue, and people; and he saith with a great voice, Fear God, and give him glory; for the hour of his judgment is come: and worship him that made the heaven and the earth, and sea and fountains of waters."
APOC. xiv, 6, 7 (R.V.).
