Do not recite many Psalms before prayer so that you will not weaken your body. By exerting your strength before prayer with other things you will not be able to recite with deveikut the main thing, i.e., the mandatory [prayers] of the day-the “Hymns of Praise,” the Shema and the Amidah. 1

Thus say first the main thing with deveikut. Then, if God gives you additional strength, recite 2 Psalms and the Song of Songs with deveikut.
