Aleister Crowley 
The book of the Law [EPUB ebook] 

‘Do what thou wilt shall be the whole of the Law. Love is the law, love under will.’
Aleister Crowley’s black magic masterpiece
The Book of the Law is the central sacred text of Thelema, written or ‘channeled’ by Crowley in 1904, who claimed it was dictated to him by a disembodied entity named ‘Aiwass’ while he spent the night in the King’s Chamber of the Great Pyramid of Giza.
