The Light of Torah

Resh Lakish says: To him who is engaged in the study of the Torah by night, the Holy One extends a thread of grace by day, as it is said, By day the Lord will command his lovingkindness, and in the night his song shall be with me.
-Avodah Zarah 3b

Commentary: Regardless of how one might choose to explain it, the study of Torah gives us that feeling of contact with the sacred, and this contact, in turn, slowly begins to transform our lives. The Zohar expands upon this passage by explaining that this thread of grace is the primordial spiritual light that has been set aside for the righteous in the world to come.
