Just wanted to say I'm reading "Coruscatio" right now, and really enjoying it.
If it's off topic then please delete this post, but I have a couple of links that might be helpful for anyone wanting more information on Libation.
The book about Leo Zeff and his techniques, by Myron Stolaroff, "The Secret Chief Revealed", can be found here, as an online version or a downloadable .pdf file:http://www.maps.org/secretchief/index.html
James Fadiman's recent book, "The Psychedelic Explorer's Guide", is another valuable resource, and the most relevant parts are free to read here:http://entheoguide.net/wiki/Manual
Going to have to order Shiva's other book soon!
