Is the sentence below OK

The following sentence is taken from a Buddhist magazine. In Buddhism, it is believed that there are ten worlds, one of which is 'the world of anger'. The sentence is about the fact that after Jingyi self-reflected and became a better person, her relationship with her husband improved.

Is the sentence below OK in relation to the above? Thanks.

Jingyi mentioned how she learnt to self-reflect after discovering that having fallen into the world of anger, she became very arrogant and showed no appreciation or respect for her husband.
