I recently encountered a beautiful teaching by the Sefat Emet (Rabbi Yehudah Aryeh Leib Alter of Ger; I've blogged his teachings many times before.) This is one of his teachings for Hoshanna Rabbah (the seventh day of Sukkot) and can be found in The Language of Truth. It's about prayer.
On Hoshanna Rabbah we beat willow branches against the ground. The willow, he says, represents speech, which connects it with prayer (prayer being, after all, a form of speech.) The willow is also associated with David, the psalmist, who said "I am my prayer before You."
Prayer is all we have for reaching God. In some sense that may seem either inadequate or chutzpahdik. On the other hand, prayer is all we need for reaching God. The leaves of the willow are shaped like lips, and our lips are the gates through which our prayers pass.
At the end of Yom Kippur we make much of how "the gates are closing." We seem to need the catharsis and the drama of dipping deep into the experience of that day as though, when that day ends, our chance to reach God were over. Though the tradition also says that the gates of repentance remain open through Hoshanna Rabbah (some say, through Shemini Atzeret, the 8th day of Sukkot)... and really, says the Sefat Emet, the gates to God are always open as long as we use our lips to pray.
Our mouths are the gates. When they are closed -- when we perceive that God is far from us -- that's because we've closed the gates ourselves. That's the heartbreaking news: our experience of God as being distant from us is our own doing! But the good news is, opening the gates is always within our power. All we have to do is open our lips.
