I think the "cultivation" here should be interpreted as: the road of self-cultivation and practice. Because truth is a field that everyone should explore, and the process of exploration is not explosive, but a long process. Some people may die suddenly without exploring the truth all their lives.

According to historical records, Qu Yuan was a minister of Chu Huaiwang in the Spring and Autumn Period. He advocated the use of talents and empowerment to make him rich, and urged him to unite against Qin, which was strongly opposed by others. Qu Yuan was so greedy that he was forced to leave his job. At the same time, he was driven out of the capital by Chu State and exiled to Yuanjiang and Xiangjiang River basins in Hunan Province.
During his exile, he wrote immortal poems such as Li Sao, Tian Wen and Jiu Ge, which worried about the country and the people. They are unique and have a far-reaching influence, and they still have a far-reaching influence on people of our time.
