The Joy of Sukkot
Yom Kippur is the time to achieve forgiveness for our wrongdoings and shortcomings. Since we don’t want G-d to judge us negatively, we try to distance ourselves from them as much as possible. We do this because we don’t want G-d to judge us harshly.
Sukkot, by contrast, comes after the judgment is sealed. We’ve already been forgiven. Sukkot, therefore, is the first opportunity to do teshuva (repentence) purely out of love. Teshuva out of love means we love G-d so much we can’t believe we committed those sins in the past, and consequently feel an incredible surge to come closer to Him more than ever before—a surge not possible if we had never committed the acts that created the distance to begin with.
