本乎此理,以观历史,以观人生,有二要义,务须记取:时的引线,与空间异。引线于空间,可以直往,亦可以逆返,我们可从北京来到上海,又可由上海返于北京。至于时间,则今日之日,不可延留,昨日之日,不能呼返。我们能从昨日来到今日,不能再由今日返于昨日。我们在此只能前进、不能回还的时的途程中,只有行动,只有作为,只有迈往,只有努进,没有一瞬徘徊的工夫,没有半点踌躇的余地。你不能旁观,你不可回顾,因为你便是引线前进的主动。你一旁观,你一回顾,便误了你在那一刹那在此不准退只准进、不准停只准行的大自然大实在中的行程,便遗在后面作了时代的落伍者。 This principle is based on history. In order to observe life, we have two important meanings. We must remember that the lead of the time is different from the space. Lead in the space, you can go straight, you can reverse, we can come to Shanghai from Beijing, Shanghai can be returned to Beijing. As for time, the date of today can not be extended, and yesterday can not be returned. We can come to today from yesterday and can no longer be returned to yesterday by yesterday. We can only move forward here. When we can not pay back the money, we can only move, only we can do it, we can only walk toward it. Only by making progress and without any hovering moment, there is no room for any hesitation. You can not look aside, you can not recall, because you are the initiative of the lead forward. When you look back, you will mistakenly miss the moment when you are not permitted to withdraw from this Chamber at that moment, and you are not permitted to stop the movement of the Great Nature of Nature.
