"Mathematics is not about numbers, equations, computations, or algorithms: it is about understanding."

True progress in farming comes from observing and learning from nature.

译文：即使只做了一天的夫妻也有百日的恩情，百日夫妻的情感就像大海一样深。赏析：一日，并不是一天，形容很短暂，夫妻关系虽然没有长久维持，分道扬镳后，也是由恩情的，不应该互相把对方视为仇人。生活中，很多夫妻因为各种原因而劳燕分飞。感情破裂无可厚非，好聚好散未尝不可，可有的夫妻却反目成仇，最终酿成悲剧的发生。

If one only wished to be happy, this could be easily accomplished; but we wish to be happier than other people, and this is always difficult, for we believe others to be happier than they are.

解析：保持纯洁朴实的本性，减少私欲杂念，抛弃圣智礼法的浮文，才能免于忧患。
