There are questions to which G-d says to be quiet, to be still, to cease to ask. The quietness, the stillness, the abandonment of being, that itself is an answer. Tetzeh 5725:4.
A common misconception is that teshuvah ("repentance") is simply an antidote to sin, and thus applies only to sinners and lowly people. In truth, teshuvah is the soul's return to and restoration of its original purity, and applies to every soul that has descended into the human state.
Rabbi Schneur Zalman of Liadi
