涅槃經遊意 1.40

1.40

解云：語雖同其意大異。彼有如來藏體，為妄所覆名之為隱，復則現出此體名之為顯。如貧女寶藏，暗室瓶瓫，則用此譬為義。

An explanation says: Although the words are the same, their intent is vastly different. In that tradition, there is an essence of the tathāgatagarbha which, being concealed by delusion, is called "concealed"; and when it appears again, this essence is called "revealed". Like the poor woman's treasure-store or the jar in a dark room, they take these parables for their meaning.
