Whoever realizes that the six senses aren’t real, that the five aggregates are fictions, that no such things can be located anywhere in the body, understands the language of Buddhas.
Bodhidharma
无乘为佛乘也。若人知六根不实，五蕴假名，遍体求之，必无定处，当知此人解佛语。
达摩祖师
若人了知眼耳鼻舌身意六根不是实有的，色受想行识五蕴只是假名，找遍身心世界，必定都找不到它们确定的真实自体，那么此人便了解了佛的语义。
般若波羅蜜多心經
五蕴皆空
无色受想行识，无眼耳鼻舌身意，无色声香味触法
