問：諸心所中遍行有五，別境有五，善中十一，不定中二所謂尋伺，如此二十三數，據善義邊並順出要，何故唯立七法為支？

Question: Among all mental factors, there are five omnipresent (sarvatraga), five specific-object (viniyata), eleven wholesome (kuśala), and two indeterminate (aniyata), namely investigation (vitarka) and reflection (vicāra). According to the wholesome side, these twenty-three factors all accord with deliverance. Why are only seven dharmas established as limbs?
