六塵

The six (sa) guṇas, qualities produced by the objects and organs of sense, i. e. sight, sound, smell, taste, touch, and idea; the organs are the 六根, 六入, 六處, and the perceptions or discernments the 六識; cf. 六境. Dust 塵 is dirt, and these six qualities are therefore the cause of all impurity. Yet 六塵說法 the Buddha made use of them to preach his law.
