四分律行事鈔資持記 2.1395

2.1395

釋第三，初引律示量。《多論》明高廣俱制，大即是廣，高量如下。廣者，準《業疏》方三肘者不合坐（五尺四寸。）疏文又引《阿含》八種勝床，俱不合陞。（金銀牙角嚴飾故勝，佛師父母從人故勝。）八指下，定尺數。周一尺二寸，為唐一尺；其餘四寸，以三寸六分為三寸，餘四分在，故云強也。《五分》作念即成持故。

In explaining the third, it first cites the Vinaya to show the measurements. The Sarvāstivāda Vinaya Vibhāṣā clarifies that both height and width are prohibited; 'large' means wide, and the measure of height is as below. As for width, according to the *Karma Commentary*, if it is three cubits square, it is not suitable to sit on (five feet four inches). The Commentary text also cites the *Āgama* on eight kinds of superior beds, none of which is suitable to mount. (Gold, silver, ivory, and horn ornamentation make them superior; being used by the Buddha, one's teacher, parents, or attendants makes them superior.) Below, 'eight finger-breadths...', it determines the number of feet. One foot two inches in the Zhou system makes one foot in the Tang; of the remaining four inches, three inches and six tenths make three inches, leaving four tenths remaining, hence it says 'slightly more'. In the Mahīśāsaka-vinaya, conceiving the thought [to keep it] immediately constitutes holding it.
