Visuddhimagga VIII-161

Parimukhaṃ satiṃ upaṭṭhapetvāti kammaṭṭhānābhimukhaṃ satiṃ ṭhapayitvā.

「置念面前」──即置念于业处的面前。

Ñ(VIII,161): Established mindfulness in front of him (parimukhaṃ satiṃ upaṭṭhapetvā) = having placed (ṭhapayitvā) mindfulness (satiṃ) facing the meditation subject (kammaṭṭhānābhimukhaṃ).

Atha vā parīti pariggahaṭṭho.

或者「遍」──为遍持之义，

Ñ: Or alternatively, the meaning can be treated here too according to the method of explanation given in the Paṭisambhidā, which is this: Pari has the sense of control (pariggaha),

Mukhanti niyyānaṭṭho.

「面前」──为出离之义，

Ñ: mukhaṃ (lit. mouth) has the sense of outlet (niyyāna),

Satīti upaṭṭhānaṭṭho.

「念」──为（心）现起之义；

Ñ: sati has the sense of establishment (upaṭṭhāna);

Tena vuccati ‘‘parimukhaṃ sati’’nti evaṃ paṭisambhidāyaṃ (paṭi. ma. 1.164) vuttanayenapettha attho daṭṭhabbo.

故名为「念面前」。当知这是依无碍解（道）所说之义。

Ñ: that is why parimukhaṃ satiṃ ("mindfulness as a controlled outlet") is said' (Ps.i,176).

Notes: the English translation is above 'the meaning can be treated here too according to the method of explanation given in the Paṭisambhidā'.

Tatrāyaṃ saṅkhepo, pariggahitaniyyānaṃ satiṃ katvāti.

综前句之略义为「遍持出离而念」。

Ñ: The meaning of it in brief is: Having made mindfulness the outlet [from opposition, forgetfulness being thereby] controlled.
