ta'anit

A '''ta'anit or taynis' (Biblical Hebrew taʿaniṯ or צוֹם ṣom'') is a fast in Judaism in which one abstains from all food and drink, including water.

==Purposes== A Jewish fast may have one or more purposes, including: Atonement for sins: Fasting is not considered the primary means of acquiring atonement; rather, sincere regret for and rectification of wrongdoing is key. Nevertheless, fasting is conducive to atonement, for it tends to precipitate contrition. Therefore, the Bible requires fasting on Yom Kippur. Because, according to the Hebrew Bible, hardship and calamitous circumstances can occur as a result of sin, fasting is often undertaken by the community or by individuals to achieve atonement and avert catastrophe. Most of the Talmud's Tractate ''Ta'anit'' ("Fast[s]") is dedicated to the protocol involved in declaring and observing fast days. Commemorative mourning: Most communal fast days that are set permanently in the Jewish calendar serve this purpose. These fasts include: Tisha B'Av, the Seventeenth of Tammuz, the Tenth of Tevet, and the Fast of Gedalia. The purpose of a fast of mourning is the demonstration that those fasting are impacted by and distraught over earlier loss. This serves to heighten appreciation of that which was lost. Supplication: For example, the Fast of Esther Commemorative gratitude: Since food and drink are corporeal needs, abstinence from them serves to provide a unique opportunity for focus on the spiritual. Indeed, the Midrash explains that fasting can potentially elevate one to the exalted level of the ministering angels. This dedication is considered appropriate gratitude to God for providing salvation. Additionally, by refraining from such basic physical indulgence, one can more greatly appreciate the dependence of humanity on God, leading to appreciation of God's beneficence in sustaining His creations.
