Wong Shan Gu, who lived during the Song Dynasty enjoyed writing poetries depicting lust and sexual affections. Once, he and the famous horse painter, Lee Bo Shi visited the established monk, Master Yuan Tong Xiu. Master Yuan first warned Lee to stop painting horses, as the deep thought of visualising the horses would land him in the realm of horse in time to come. Followed, he alerted Wong that a scholar like him should not waste his artistic talent on depicting unwholesome words and thoughts that had no beneficial contribution to the society. Wong mocked at the Master's words, asking sacarstically if he would be turning into a horse like Lee. The stern Master replied earnestly that even Lee in the course of painting horses focuseed his thought and eventually ended up in the lower realm of his depiction, but that was his own problem. However, your writing had provoked the minds of many with lust and undesirable thoughts, and might lead them to disastrous consequences. Such unwholesome cause would land you in hell eventually. Wong was stunned by the wise man's words, and knowing that the well-respected Master would not lie, he quickly repented his actions and vowed not to publish those unwholesome writing ever again.
Editor commentary: The reincarnation and suffering within the six realms could not be seen by sentient beings and hence many do not believe in the law of cause and effect. It would be too late by the time they suffered from the effect of their misdeeds. How can we not be cautious in our doings?
