Prayer And Remembrance

Ἐν καιρῷ μνήμης Θεοῦ πολυπλασίασον δέησιν, ἵνα ὅταν ἐπιλάθῃς, ὁ Κύριος ὑπομνήσῃ σε. Ἅγιος Μάρκος ὁ Ἐρημίτης, Περὶ Νόμου Πνευματικοῦ Migne PG 65.908d

At any time comes thought of God, let prayers be multiplied, that when you are forgetful, the Lord remembers you. Saint Mark The Ascetic, On The Spiritual Law.
