"November 25, 1889 In the absence of truth, there certainly is no truth. In the absence of the path, there certainly is no path. Attending the lectures one after another, you say, “I am done for another month,” yet that will serve no purpose unless the truth settles in your mind. No matter how many lectures you claim to have attended, you may have no effectiveness depending on whether or not there is truth in your mind. If you complete the order of the lectures, I shall bestow the Sazuke upon you. Nonetheless, the day may come when you will drop it."
