四分律行事鈔資持記 2.1445

2.1445

The precept against swinging the arms. (The censure is as above.) 'Before and behind'—'behind' means to the rear. Among the non-offenses, 'other circumstances' means either vicious beasts or carrying brambles; 'raising the hand to fend them off' applies to the preceding three situations. As for 'crossing by swimming,' one must swing both arms, hence [it is excused].
