此觸別名又二十二等者。此諸觸相依八種因之所建立。澁之一種依摩建立。滑之一種依相建立。輕重二種依秤建立。緩急二種依執建立。冷煖二種依觸建立。粘養強弱依雜建立。地水雜故粘。風火雜故癢。地風雜故強。水火雜故弱。依界平等建立勇息。四大界平無畏故勇。平等安和無動故息。界不平等建立餘觸。風火增故飢。地火增故渴。地水增故飽。風火增故悶。病老死等皆由大增以有隨增。以有隨增名不平等。由此等相於身覺故故皆名觸。

Regarding "these tactile objects also have twenty-two distinct designations, etc.": these marks of tangible objects are established on the basis of eight causes. The one kind, roughness, is established on the basis of friction. The one kind, smoothness, is established on the basis of appearance. The two kinds, lightness and heaviness, are established on the basis of weighing. The two kinds, slowness and urgency, are established on the basis of grasping. The two kinds, cold and warmth, are established on the basis of touch. Stickiness, itching, stiffness, and weakness are established on the basis of mixture: because earth and water are mixed, there is stickiness; because wind and fire are mixed, there is itching; because earth and wind are mixed, there is stiffness; because water and fire are mixed, there is weakness. On the basis of the equilibrium of elements, vigor and repose are established: when the four great elements are in equilibrium, being without fear, there is vigor; being in balanced harmony and without disturbance, there is repose. On the basis of the non-equilibrium of elements, the remaining tangible objects are established: because wind and fire increase, there is hunger; because earth and fire increase, there is thirst; because earth and water increase, there is repletion; because wind and fire increase, there is stifling distress. Illness, aging, death, and so forth are all caused by the increase of the great elements, because there is an accompanying increase; because of this accompanying increase, it is called non-equilibrium. Because these marks are felt by the body, they are all called tangible objects.
