禪林寶訓 2.18

2.18

靈源謂伊川先生曰。禍能生福福能生禍。禍生於福者。緣處災危之際切於思安深於求理。遂能祇畏敬謹。故福之生也。宜矣。福生於禍者。緣居安泰之時。縱其奢欲肆其驕怠。尤多輕忽侮慢。故禍之生也。宜矣。聖人云。多難成其志。無難喪其身。得乃喪之端。喪乃得之理。是知福不可屢僥倖。得不可常覬覦。居福以慮禍。則其福可保。見得而慮喪。則其得必臻。故君子安不忘危理不忘亂者也（筆帖）。

Lingyuan said to Master Yichuan: 'Misfortune can produce fortune, and fortune can produce misfortune. Misfortune producing fortune occurs because when dwelling amidst disaster and danger, one is earnest in seeking security and deep in seeking principle; thus one can be reverent, fearful, and circumspect. Therefore, it is natural that fortune arises. Fortune producing misfortune occurs because when dwelling in peace and tranquility, one indulges one's extravagant desires, gives free rein to arrogance and negligence, and shows especially great slight and insolence. Therefore, it is natural that misfortune arises. The sage said: "Many hardships fulfill one's resolve; absence of hardships ruins one's person." Gain is the beginning of loss; loss is the principle of gain. From this we know that fortune cannot be repeatedly relied upon through luck, nor can gain be constantly coveted. Dwelling in fortune while reflecting on misfortune, one's fortune can be preserved; seeing gain while reflecting on loss, one's gain will surely be realized. Therefore, the exemplary person does not forget danger in times of safety, nor forget chaos in times of order.' (*Bitie*).
