Ñ(VIII,155): Or alternatively, this mindfulness of breathing as a meditation subject—which is foremost among the various meditation subjects of all Buddhas, [some] Paccekabuddhas and [some] Buddhas' disciples as a basis for attaining distinction and abiding in bliss here and now—is not easy to develop without leaving the neighbourhood of villages, which resound with the noises of women, men, elephants, horses, etc., noise being a thorn to jhāna (see A.v,135),

Ñ: whereas in the forest away from a village a meditator can at his ease set about discerning this meditation subject and achieve the fourth jhāna in mindfulness of breathing; and then, by making that same jhāna the basis for comprehension of formations [with insight] (Ch. XX, §2f.), he can reach Arahantship, the highest fruit.
