四分律行事鈔資持記 2.1048

2.1048

緣中。準疏有六，但於三中分出四五。三同一船。四順流上下，文開直渡，必約上下往來方結；又但取作意，纔入即犯，不待船行。第五謂非直渡失濟之緣。第六雙脚入犯，律中一脚在船，一脚在地，吉羅。準疏俗女亦犯。

Among the conditions: According to the Commentary, there are six, but conditions four and five are divided out of the third. Third, being in the same boat. Fourth, going up or down with the current; the text permits an exception for crossing directly across, so the offense must be determined in terms of travelling up or down; furthermore, it takes merely the intention: as soon as one steps in, the offense is incurred, without waiting for the boat to move. Fifth refers to circumstances not of crossing straight across or of losing passage. Sixth, stepping in with both feet incurs the offense; in the Vinaya, having one foot in the boat and one foot on land is a duṣkṛta. According to the Commentary, travelling with a laywoman also constitutes an offense.
