On Truth
Truth is verifiable, either directly (as with Science) or via inference. The supernals may be beyond reason, but in order for it to reach Malkuth it has to pass through the Ruach. If your "Truth" fails to match what is known &/or verifiable, then I will bet that it isn't Truth, but instead delusion of the kind Crowley warns us against in the "Dangers of Mysticism."
