4.397

復有餘師說：唯約無漏，有處緣涅槃心起滅定時言觸三觸，以無漏故名為不動，無所有處地所攝故名無所有，緣涅槃故名為無相。

Still other masters say: Strictly in terms of the taintless, when a mind taking nirvāṇa as object in some state arises from the concentration of cessation, it is said to touch the three contacts: because it is taintless, it is termed 'immovable'; because it is subsumed in the stage of the station of nothingness, it is termed 'nothingness'; because it takes nirvāṇa as object, it is termed 'signless'.
