Aha

Crowley called AHA! "my greatest magical poem". It is an exposition in poetic language of the ways of attainment and the results obtained. It particularly highlights the two central experiences of Initiation: the Knowledge and Conversation of the Holy Guardian Angel and the Crossing of the Abyss. On a more personal level, it signaled the end of Crowley's struggle against The Book of the Law and his role as Prophet of the New Aeon.
