One of the most beautiful teachings I have encountered about Yom Kippur is from the Sfat Emet. The Sfat Emet uses the symbology and metaphor of a mikvah to talk about what Yom Kippur is and how it functions. Yom Kippur is this day of total immersion, total unity with God. On Yom Kippur, we are forgiven, as God has spoken, which we say multiple times, so we know that at the end of the holiest day of the year, we will have a clean slate as it were, able to begin again. Yom Kippur is also very much about coming close to God. Just as a kosher immersion in a mikvah is an immersion in which the total body is submerged and there’s no barrier between the physical body and the waters of the mikvah, and just as mikvah waters are mayyim chayyim—living waters, on Yom Kippur, we ask repeatedly to be written and later sealed in the Book of Life for the coming year. And we don’t merely ask to be sealed in the Book of Life. We also ask God to write and seal us in the book of long life, good deeds, etc. We are immersed not only in reflection about the year which has past but we look forward to choosing life in the New Year. When we experience that day of complete unity with God, we are completely immersed in prayer and confession, supplication and fasting. These spiritual and ritual acts are the vehicles through which we achieve that unity with God. Yom Kippur has a unique character all its own. On other days, though we hope that our avodat hashem will get us there, on Yom Kippur, our tradition gives us particular ritual and spiritual tools that we can use in achieving that unity. We have a particularly special access to God on Yom Kippur that, though God is with us always, we don’t have the same level of immediacy. The difficulty, however, is that as beautiful as the Sfat Emet’s teaching is here, it is so aspirational. How many of us can truly say that on Yom Kippur we are achieving this unity all of the time? I think that perhaps a balanced way to think about this is that we are always striving for this unity, that even if we achieve this unity for only a few moments, we have still gotten somewhere spiritually significant and important.
