23.241

言若增若減，若取若捨者，一一通釋，五塵五根增勝，故曰若增，或有時損減，故曰若減，根境增故能取，根境減故能捨，故曰若取若捨。

Regarding the words 'whether increasing or decreasing, whether taking or relinquishing': explaining each comprehensively, the abundance and flourishing of the five sense objects and five faculties is called 'increasing'; their occasional diminution is called 'decreasing'; because faculties and objects increase, they are able to take; because faculties and objects decrease, they are able to relinquish; hence it says 'whether taking or relinquishing'.
