Awareness of Hashem
Tefillah is Awareness of Hashem. The most important part of our lives is to become more Aware of Hashem. When we daven, we are not giving Hashem direction what to do for us, nor are we telling Him what is necessary for us. Tefillah means L’hispalel, from the word pilul, which means to make yourself think – when we ask Hashem for something, we are thinking about Him and His presence in our lives, and that is the true purpose of Tefillah.
