“21. If he is secure at all points, be prepared for him. If he is in superior strength, evade him. 22. If your opponent is of choleric temper, seek to irritate him. Pretend to be weak, that he may grow arrogant. [Wang Tzu, quoted by Tu Yu, says that the good tactician plays with his adversary as a cat plays with a mouse, first feigning weakness and immobility, and then suddenly pouncing upon him.] 23. If he is taking his ease, give him no rest. [This is probably the meaning though Mei Yao-ch’en has the note: “while we are taking our ease, wait for the enemy to tire himself out.” The YU LAN has “Lure him on and tire him out.”] If his forces are united, separate them. [Less plausible is the interpretation favored by most of the commentators: “If sovereign and subject are in accord, put division between them.”] 24. Attack him where he is unprepared, appear where you are not expected. 25. These military devices, leading to victory, must not be divulged beforehand. 26. Now the general who wins a battle makes many calculations in his temple ere the battle is fought. [Chang Yu tells us that in ancient times it was customary for a temple to be set apart for the use of a general who was about to take the field, in order that he might there elaborate his plan of campaign.] The general who loses a battle makes but few calculations beforehand. Thus do many calculations lead to victory, and few calculations to defeat: how much more no calculation at all! It is by attention to this point that I can foresee who is likely to win or lose.”
Thomas Merton wrote more than 70 books, mostly on spirituality, as well as scores of essays and reviews. Merton was a keen proponent of interfaith understanding.
Interest in his work contributed to a rise in spiritual exploration beginning in the 1960s and 1970s in the US. Merton's letters and diaries, reveal the intensity with which their author focused on social justice issues, including the civil rights movement and proliferation of nuclear arms. He had prohibited their publication for 25 years after his death. Publication raised new interest in Merton's life.
