3.108

恒受離繫受非有繫受者，諸有漏受離煩惱增繫及無漏受名離繫受，非必一切皆無漏受。梵行已立者，滅諦智道諦滿，究竟涅槃於滅諦滿，顯求涅槃者於佛所得滅諦滿足。

Concerning "constantly experiencing unbound feeling, not bound feeling": tainted feelings freed from the augmenting bonds of affliction, as well as untainted feelings, are called unbound feeling; it is not necessary that all are untainted feelings. Concerning "the holy life has been established": knowledge of the truth of cessation and the truth of the path is perfected; ultimate nirvāṇa is perfected in the truth of cessation, showing that one who seeks nirvāṇa attains perfection of the truth of cessation from the Buddha.
