"There is one spiritual activity that the sages regarded as even higher than prayer: namely, study of Torah, God's word to humanity and His covenant with our ancestors and us (Shabbat 10a). The entire Pirkei Avot (Ethics of the Fathers) is a set of variations on the theme of a life devoted to Torah study. In prayer, we speak to God. Through Torah, God speaks to us. Praying, we speak. Studying, we listen."
Rabbi Jonathan Sacks
