Hashem, as I open my Siddur, let me pray with proper kavanah. Let me pray with sincerity, paying careful attention to every word I utter. Hashem, let me concentrate with my whole being on the meaning of each and every word, sentence and prayer. Keep my mind from wandering to other subjects, and keep me from neglecting to put my heart and soul in to each and every prayer, praise and blessing. May my prayer come before You, O Hashem, at a time of grace, and may it be accepted favorably by You. Amen.
