The Gemara says “כל הקובע מקום לתפילתו, אלקי אברהם בעזרו”(“Kol Hakove’a Makom L’tfilaso, Elokei Avraham B’ezro”), “Anyone who makes for himself a set place for his tefillah, the G-d of Avraham will be his aid“ (Brachos 6b). When one invests in prayer in a certain place, that place becomes associated with the thoughts and feelings that he had there, and the next time he prays there, those thoughts are reawakened again, thus enabling him to continue growing and attaining perfection and Awareness of Hashem from one tefillah to the next.
