又汝應於念住加行已下，第二教依聚落護身心。若於如是諸境界相不應策發諸根等者，景云：若於染境不應策根莫作功用，若於生善境界汝應策根正作功用，隔之言路。泰云：入聚落時，見惡境界不策諸根，若見母邑即策諸根以住正念。

From "Moreover, in the preparatory practice of the applications of mindfulness, you should..." onward, the second part instructs on relying on villages to protect the body and mind. Regarding "if toward such objective marks one should not stimulate the sense faculties, and so forth": Jing says: if toward defiled objects, one should not stimulate the faculties, making no effort; if toward objects that generate wholesome qualities, you should stimulate the faculties, making correct effort, which separates the paths of speech. Tai says: when entering a village, seeing bad objects, one does not stimulate the sense faculties; if seeing women, one then stimulates the sense faculties in order to abide in correct mindfulness.
