俱舍論疏 1.187

1.187

論「隨境強盛至令相續故」，答也。境若均平，舌識先起。由食欲引起身，令展轉相續持食入口，欲取舌味故。境若均平，先應覺味，此就多分。若為知冷、煖，即合先覺於觸。今詳取境先後，略由四緣：一由作意不同、二由根有明昧、三由境有強弱、四由境有新舊。

The commentary states: "Following the intensity of the object... because of causing continuous succession." This is the answer. If the objects are equally balanced, the gustatory consciousness arises first. Desiring food, it induces the body to successively hold food and put it into the mouth, because one desires to take the flavor with the tongue. If the objects are balanced, one should first perceive the flavor; this is spoken according to the majority of cases. If it is for the sake of knowing cold and warmth, then one should first perceive the tangible. Examining now the sequence of apprehending objects, it is roughly due to four conditions: first, due to differences in attention; second, due to the faculties being sharp or dull; third, due to the objects being strong or weak; fourth, due to the objects being new or old.
