佛遺教經論疏節要 1.438

1.438

〔補註〕師資者，言一眾聚散，未有主常領伴、伴常隨主者也。五陰者，言一身聚散，色陰則四大合而必離，四陰則妄念起而必滅。故曰一切皆無常也。

[Supplementary note] Master and disciples refers to the gathering and dispersal of a single assembly: there has never been a leader who permanently leads the companions, nor companions who permanently follow the leader. The five aggregates refers to the gathering and dispersal of a single body: for the aggregate of form, the four great elements come together and must separate; for the four [mental] aggregates, deluded thoughts arise and must cease. Therefore it is said: "All things are impermanent."
