It is a well known custom to stay up all night learning Torah during the festival of Shavuot. A common explanation is that the all-night learning is the best way to show our appreciation for receiving the gift of the Torah on this date during our exodus from Egypt over 3,000 years ago. However, there is much more at play here during this all-night study which is called, Leyl Tikkun Shavuot. As is implied by this phrase, the night of study is a repair (tikkun), a correction of sorts. The Midrash tells us that the Children of Israel who camped at Mt. Sinai slept so hard during this night that Gd had to wake them in order to give them the gift of the Torah. Our intense night of study is to make amends for our ancestors and also to make amends for our own indolent study habits during the year. How ironic that the people most likely to follow this custom of all-night study are those very individuals who set aside time during the regular week for Torah study. The Torah is a mountain of knowledge that no individual will ever master, but a daily dose of the small rocks and pebbles that make up that mountain add up to soul of delight and a life of meaning and commitment. And, after all, if not now – when?
