How to Split Overly Long Sentences into Two Without Affecting Other Sentences in segments Processing

[zxl777]

My current setting is that each complete sentence is on one line, each ending with a period '.'.
However, occasionally there are overly long sentences.
How can I split these long sentences into two using certain rules, without affecting the other sentences?

The current Regrouping Methods apply to all sentences, so setting a rule will impact others. This leads to complex debugging.
But I really only want to handle a few particularly long sentences.

Example

It's very useful for meditation because in the Heart Sutra, it says that by realizing all of these mechanisms of mind or these these aggregates by realizing them to be empty of self we become enlightened.
We detach our sense of self from them.
