Yom Kippur, the greatest and holiest day of the year, is dedicated as a day of forgiveness and pardon for the iniquities of Israel. As our sages said: "There were no good days for Israel like Yom Kippur," because "there is forgiveness and pardon in it."

In the words of Rabbi Akiva, an additional depth of the day's joy is revealed: "Happy are you, Israel, before whom do you purify yourselves, and who purifies you? Your Father in heaven." The joy of the day is not only over the forgiveness of iniquities, but over the privilege of returning and standing before our Father in heaven, and that He Himself purifies us.

Halachic Guidelines for Yom Kippur

Eating and drinking on Yom Kippur: One who eats a ke-koseves ha-gasa (approx. 30 cubic centimeters) or drinks a malei lugmav (cheekful, approx. 40 ml) is liable by Torah law. Eating or drinking lesser amounts (chatzi shiur) is also forbidden by Torah law. If the eating or drinking does not span the time of "achilat pras" (calculated stringently as 9 minutes), the quantities combine together.

Laws of the sick on Yom Kippur: A dangerously ill person is exempt from fasting. Someone who requires only drinking should drink in measured amounts (less than a cheekful) at intervals of 9 minutes. If medical necessity requires shorter intervals, it may be shortened to 4 minutes or 2 minutes, and the required amount should be taken in several sips rather than one large sip.

Education of Minors and Ne'ilah Prayer

Education of children: Minors are permitted to eat and drink on Yom Kippur. Regarding fasting for hours, healthy children from the age of nine, and frail children from age ten, are trained to delay their meals according to their strength. Children reaching bar or bat mitzvah age are fully obligated to fast.

Ne'ilah prayer: Ne'ilah is the sealing of the verdict written on Rosh Hashanah. One must strengthen oneself greatly in this prayer, utilizing every moment for sincere repentance and prayer to be sealed in the Book of Good Life.
