Tikkun Chatzos — Midnight Rising

One should arise and mourn greatly over the destruction of the Holy Temple — over the concealment of the light of the true Tzaddik — and over one's sins, iniquities, transgressions, evil traits and evil desires that delay the rebuilding of the Temple. One should find oneself within everything that passes over one during the recitation of Tikkun Chatzos, and beseech Hashem Yisborach for the redemption and salvation of all Yisroel — and also for the redemption of one's own soul from the evil inclination that always lies in wait. The time of midnight always begins six hours after the emergence of the stars, and its period extends for two hours.
