During these weeks, it is customary to be more careful not to violate any of the sexually-related transgressions commanded in the Torah. Some have the customs of studying laws relating to such transgressions, fasting and giving extra "tzedakah" (charity) during this time, and of reciting Selichos and other "tikkunim" (Kabbalistic prayers or meditations) designed to counteract their harmful effects. On the Shabbatot (Saturdays, the Jewish Sabbath) when these weekly portions of the Torah are read, some take upon themselves to refrain from speaking, except words of prayer and Torah. This type of fast is called a "ta'anit dibbur" ().
