Lenten Prayer of Saint Ephraim

The Prayer of St. Ephraim (Greek: Εὐχή τοῦ Ὁσίου Ἐφραίμ, Euchē tou Hosiou Ephraim), is a prayer attributed to Saint Ephraim the Syrian used with emphasis during the Great Lent. This prayer is considered to be the most succinct summation of the spirit of Great Lent and is hence the Lenten prayer 'par excellence', prayed during all Lenten weekday services, such as the Liturgy of the Presanctified Gifts, and many more times in private. 

The prayer is accompanied by prostrations. The most common practice has one after each line of the prayer, then twelve bows/prostrations either in silence or accompanied by "Lord have mercy on me a sinner" , followed by one at the end of a repeat of the entire prayer, with a final prostration.

O Lord and Master of my life,
Keep from me the spirit if indifference
And discouragement,
Lust of power, and idle chatter.

Instead, grant to me, Your servant,
The spirit of wholeness of being,
Humble-mindedness, patience, and love.

O Lord and King,
Grant me the grace to be aware of my sins
And not to judge my brother and sister,
For You are blessed,
Now and ever and forever. Amen.

In Greek:
Κύριε καὶ Δέσποτα τῆς ζωῆς μου, πνεῦμα ἀργίας, περιεργίας, φιλαρχίας, καὶ ἀργολογίας μή μοι δῷς.
Πνεῦμα δὲ σωφροσύνης, ταπεινοφροσύνης, ὑπομονῆς, καὶ ἀγάπης χάρισαί μοι τῷ σῷ δούλῳ.
Ναί, Κύριε Βασιλεῦ, δώρησαι μοι τοῦ ὁρᾶν τὰ ἐμὰ πταίσματα, καὶ μὴ κατακρίνειν τὸν ἀδελφόν μου, ὅτι εὐλογητὸς εἶ, εἰς τοὺς αἰῶνας τῶν αἰώνων. Ἀμήν.
