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.
