四分律行事鈔資持記 1.1116

1.1116

忘成中，初釋名相。身已在界，不憶加結；佛開成夏，故云忘成。律下，引示。律中四法，次第相由。故指心念為忘。必忘對首，例亦同開。故知下，準決；初示文局。以律本緣開外來故。必下，顯義通。但約要心，不局內外。初明舊住有要亦通，下明外客無要反塞。言為事者，別有所務，明非要故。

In unmindful completion: first, it explains the terminology and characteristics. One's body is already within the boundary, but one does not remember to apply the formula; the Buddha made an exception so that the rains retreat is completed, hence it is called 'unmindful completion'. Under 'the Vinaya...', it cites and demonstrates. In the Vinaya, the four procedures successively derive from one another. Hence it refers to mental intention as unmindful. If one forgets face-to-face, by analogy it is also granted an exception. Under 'hence we know...', it makes a determination: first showing that the text is restricted, because the Vinaya's root condition grants an exception for coming from outside. Under 'if...', it reveals that the meaning is comprehensive: it concerns only an essential intention and is not restricted to inside or outside. First, it clarifies that for a long-time resident, having the essential intention also applies; below, it clarifies that for an outside guest, lacking the essential intention conversely blocks it. The phrase 'for the sake of affairs' means having other business, clarifying that it is not the essential intention.
