A master of lies... He will know what kind and mode of deception is taking place at any moment set before him. He will know the lies of magic are the same as the lies of science. He must have detailed knowledge to the exactitude of a mathematician on why mathematics is a falsehood. A master of lies is most persuasive, and he knows how to hide his persuasion. He knows what purpose his lie serves, whether good or evil, beautiful or ugly or simply complex in how truth and lies are woven into the fabric of space-time.
 
He has found the crack in the wholeness of his being, from where he will shine his lights and darknesses. He will know why he shines a darkness instead of a light, what the dangers are and how to avoid them. It is not mastery if his lies cause him harm. In other words, mastery over lies is not different from a mastery of truth.

And a so-called master of truth only requires blind faith. Waving the flag of truth, he will be insulted if called a liar, as if lies were not integral to our existence on earth. He is blind to his own lies and manipulations, believing them to be right and true.

"Errat ergo sum" -St. Augustine

Come with me, I will guide you through the nightmare land of lies. And when you have crossed this valley of shadow, you will have a mastery that is more valuable than any fact.
