When you are full and warm, you will have lustful thoughts: bǎo nuǎn sī yín yù, when you are full and warm, you will have lustful thoughts. "Lust" here should generally refer to evil, bad desires, things that make people indulge in indulgence and cannot extricate themselves.
From: Ming Dynasty Jia Zhongming's "Dual Jade Comb".
This sentence originally came from Mencius, "Wealth cannot be promiscuous" and later evolved.
The next sentence of "having enough food and clothing and thinking about lust" is contradictory to each other, and the next sentence is "hunger and cold lead to stealing the heart". In layman's terms, these two sentences describe the depravity of human nature, which coincides with Xunzi's "the beginning of man" "Nature is inherently evil." Once people are satisfied with food and clothing, they will begin to pursue higher-level desires. Once people are hungry and cold, they will have animal desires to harm others.
Extended information
These two sentences may seem simple, but they are both wise words. These two sentences are from the juvenile enlightenment book "Zengguang Xianwen". No wonder the ancients were able to summarize so many life experiences. It turned out that they received this kind of education from childhood. The two behaviors of "thinking about lust" and "having the intention to steal" are very extreme bad behaviors.
The meaning in ancient times is: use these two sentences to criticize and warn against the luxurious and corrupt lives of wealthy children in ancient times, as well as their unhealthy and skewed views and attitudes. These two sentences remind people that the human spirit should be positive and not do whatever they want.
Only after meeting the lowest level of needs, people will have the motivation and ideas to meet the next level of needs. However, after people meet their own needs, they will have no goals and no desire to work hard. Struggle, without the pursuit of life, will result in repeated degradation, and it will never be possible to achieve spiritual satisfaction. Now, we should always remind ourselves to be a promising person, grow into a towering tree, and become the pillar of the country.
