After sending off Fayue, Xu Qing lingered on the fluctuations of his Divine Soul.
The cultivation of the Divine Soul is quite interesting. If one continuously maintains a state of undisturbed tranquility, like an ancient well without ripples, it is beneficial for the Divine Soul to eliminate stray thoughts and maintain purity. When contemplating issues, one tends to be more rational.
"But this does not lead to a faster increase in the power of the Divine Soul than the drastic ups and downs of emotions."
The fluctuations of emotions, the enhancement of desires, and so on, can all strengthen the Divine Soul, but at the same time, the Divine Soul can become polluted, as if by foreign contaminants, falling easily into an irrational state and generating impurities...
Xu Qing unfolded a sheet of white paper, took up the brush on the desk, and wrote down a line,
"Subdue the heart's monkey and tether the mind's horse."
