坑。 译本有“问题”挺正常， 坛经 也有挺多版本的，有的内容“差异”挺大的。。。

拿那个有争议的讲三时的出来说一下，英文版还找了一阵子。。。

世（addhā，亦可译为「时段」）

无明与行属于过去世，因为这里所指的是属于过去生

发帖数: 17520 | 2 这就要看你如何诠释意志力的这个名词了
自己的智慧自然而然？能够自然而然， 僧团为什么要有戒律？
诱惑这个东西所缘没有具足， 你就不能够用不需要“强大意志力”去抵触
这种话去大而化之。。。
比方说狗吃屎，你从一个不吃屎的人的角度去说 我不需要强大的意识力去抵触吃屎的
这个event， 是比较可笑的。
所以说毒品也是一样， 如果你在一个毒品环绕的境地， 你才有资格说
你不需要意志力
很多事情是要脚踏实地的站在自己能够解决的范围之内去看待问题的
而你表达的方式就是站在”修行深厚“的人的高度（你没这么说）去诠释
”意志力“， 初期的修行是需要fabricate的， 也就是造船， 意志力或许可以视为船
的动力， 即使是修行到了很深的阶段， ”意志力“也是需要的（某书中看到的），
当然你可以认为不能用意志力这个词来解释这种动力
其实我觉得简约的说法可以是5善根的所缘， 那就是5力， 这个东西不是
我想， 我会， 我做，那么简单， 是一个迂回辗转向前对”未来“控制的一种状态。

发帖数: 17520 | 4 日常生活的行住坐臥都要保持正念，個人感覺初級的正念， 正定， 正精進
的涵蓋範疇是包含了7覺支
而大家似乎容易忽視擇法覺支， 也就是對當下的身心現象的判斷，
對煩惱的厭離， 對輕安等的嚮往， 渐次而起，渐次而得
如果不知道“應該” 少上網，多做“益事”，是不是修行， 那麼就是對這個
擇法覺支的輕視了
沒有什麼東西是應該升起， 也沒有什麼東西是不應該升起
坦然接受就是已經進入拒絕investigate 的狀態了， 就是認同了
當然也不能拒絕， 所以， 不認同不拒絕是同時， 這樣做的狀態是能夠
更加平等地看著這些東西， 然後還是要做出判斷的
大家的mental state 都是出於一個需要“改變”的狀態
都是需要清淨的， 這個過程沒有discernment 是不能成事的 |
