This practice became formalized under the influence of the Kabbalah during the period of R. Isaac Luria. Two separate forms of the service developed known as Tikkun Rahel and Tikkun Le'ah. Tikkun Rahel, consisting of Psalms 137 and 79 and Tehinnot on the destruction of the Temple, is recited on days when Tahanun is said. On the Sabbath, festivals, and days when Tahanun is omitted, Tikkun Le'ah, consisting of more joyful psalms, such as 111 and 126, and selections from the Mishnah (Tamid ch. 1), is recited.
