四分律行事鈔資持記 2.533

In explaining places of hindrance: "danger" relates to harming oneself, while "hindrance" relies on obstructing others, hence they are divided into two categories. The Dharmaguptaka-vinaya specifically mentions grass carts, because grass carts are the largest, and thus are taken as the measure. The Samantapāsādikā lists five kinds. Śītavana is translated here as cold forest, a place where corpses are discarded. "Mark" means record. Guāng refers to the rungs of a ladder. A fist is one cubit, which is one foot eight inches; up and down there are twelve spaces, calculating to two zhang, one foot, and six inches. (It does not allow a horizontal ladder to turn around, hence it is called a hindrance.) The Daśādhyāya-vinaya's nine marks are all stated looking from outside the hut inward, which is why it is marked first. From "There are…" downward, they are listed and shown: five kinds are ground protected by others; four kinds are precipitous and obstructive places. (According to the places of hindrance in the Samantapāsādikā and the Daśādhyāya-vinaya, they overlap with the places of danger in the Dharmaguptaka-vinaya; this is simply due to differences in compilation.)
