道五 - Tao Chapter 05

天地不仁 以万物为刍狗

圣人不仁 以百姓为刍狗

天地之间 其犹橐籥与

虚而不屈 动而愈出

多闻数穷 不若守于中

天地无所谓与人交心，因此世间万物各司其职（自家饲养的牛羊等草食牲畜和牧羊犬牧牛犬的关系），自成生态；通达事理的人不需要与人交心（也能明事理），明了人生百态各有所因、自成其事。 天地之间此消彼长、生生不息（很难穷尽），就像脚踩式气筒（古时鼓风吹火用）一样，自然回弹的时候内里空虚（进气），轻踩的时候送风（出气）越大。 见闻越多，越觉得自己的知识不够用（被穷尽了）。这个时候，不妨坚守自己认为的正信中道，以此做出决断。

Heaven and earth do not care about interacting with people, so all things in the world each perform their own duties, creating their own ecosystems; those who understand principles do not need to interact with people (and can still understand principles), they understand the various circumstances of human life and each has its own cause, and create their own events.

The world between heaven and earth is constantly changing, with this dying out and that flourishing (it is hard to exhaust it), like a foot-operated bellows (used in ancient times for blowing fire), when it is naturally rebounding, it is empty inside (inhaling) and when it is lightly stepped on, the wind (exhaling) is greater.

The more one sees and hears, the more one feels that their knowledge is not enough (has been exhausted). At this time, it is not bad to stick to the middle way that one believes in, and make decisions based on it.
