Self-cultivation, not good at lust, this is Mencius' point of view. Mencius believed that the best way to cultivate one's morality is to reduce material desires. Mencius advocated that people should try to minimize the pursuit of material desires such as nobility and beauty, because if a person has too much greed, it will damage his benevolence and righteousness. Through abstinence, people can keep the purity of their hearts and achieve the effect of self-cultivation.
