The True Thought

You concede that the truth is a thought, but say that not every thought is a true one, or, as you are also likely to express it, not every thought is truly and really a thought. And by what do you measure and recognize the thought? By your impotence, to wit, by your being no longer able to make any successful assault on it! When it overpowers you, inspires you, and carries you away, then you hold it to be the true one. Its dominion over you certifies to you its truth; and, when it possesses you, and you are possessed by it, then you feel well with it, for then you have found your -- lord and master.
