Orthodox Prayer, How to pray? An Orthodox perspective

Arise, you, O children of the light, to praise the Lord of Hosts, that He may grant us the salvation of our souls. When we stand in the flesh before You, take away from our minds the sleep of forgetfulness, and grant us alertness, in order that we understand how to stand up before You at the time of prayer, and send up to You the appropriate doxology, and win the forgiveness of our many sins.
