Shen Yue furrowed his brows but said no more. What he wanted to say was different from what Giant Li had expressed.
He and Giant Li were discussing a common emotion in cultivation practice, which also greatly hindered progress—regret!
In secular terms, regret often means remorse over things not done.
Regret for not having accomplished something and the repeated indulgence in such emotions could prevent one from moving forward and building anew. This was intricately related to self-torture; initially, you might self-torture out of remorse, but over time, it could become an addictive mental habit. In the end, it would cause pervasive harm to oneself, making it difficult to escape the cage.
In cultivation, there were many ways to deal with regret, but certainly not through ignoring it or shamelessness.
