Visuddhimagga IV-136

Paccavekkhaṇavasī pana āvajjanavasiyā eva vuttā.

观察自在同于转向自在所说。

Ñ(IV,136): Mastery in reviewing is described in the same way as mastery in adverting;

Paccavekkhaṇajavanāneva hi tattha āvajjanānantarānīti.

即在那里的转向心以后而易以观察的诸速行心。

Ñ: for the reviewing impulsions are in fact those next to the adverting mentioned there (§132).
