Yuantong said to Dajue: “The ancient sages governed the mind before it sprouted and guarded against passions before they fell into disorder. For if there is preparation, there will be no calamity. That is why they ‘doubled the gates and sounded the watchman's clapper to guard against violent intruders,’ drawing this from [the hexagram] Yu (Enthusiasm / Preparation). If a matter is prepared beforehand, it is easy; if done hastily, it is truly difficult. That the worthy philosophers of old had lifelong concerns but never a single morning’s calamity—truly it lies in this!” (*Collection of Jiufeng*)
