Religious fasting

Religious fasting is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Religious fasting rather than just read about it. In short: Various religions prescribe or recommend religious or faith-based fasting. Examples from the Abrahamic religions include Lent in Christianity; Ramadan in Islam; Yom Kippur, Tisha B'av, Fast of Esther, Fast of Gedalia, the Seventeenth of Tammuz, and the Tenth of Tevet in Judaism.

Key takeaways

  • Religious fasting belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Religious fasting to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Religious fasting from memory before moving on to harder problems.

Reference excerpt

Various religions prescribe or recommend religious or faith-based fasting. Examples from the Abrahamic religions include Lent in Christianity; Ramadan in Islam; Yom Kippur, Tisha B'av, Fast of Esther, Fast of Gedalia, the Seventeenth of Tammuz, and the Tenth of Tevet in Judaism. Muslims fast during the month of Ramadan each year. The fast includes refraining from consuming any food or liquid from the break of dawn until sunset. Details of fasting practices differ. Oriental Orthodox Christians and Eastern Orthodox Christians fast during specified fasting seasons of the year, which include not only the better-known Great Lent, but also fasts on every Wednesday and Friday (except on special holidays), together with extended fasting periods before Christmas (the Nativity Fast), after Easter (the Apostles Fast) and in early August (the Dormition Fast). Members of the Church of Jesus Christ of Latter-day Saints (Mormons) fast for a full 24-hour period once per month – usually before the main meal on the first Saturday of the month and ending with the main meal on the following Sunday – this is termed by the church as fast and testimony weekend. Many church members use this time to pray and meditate to increase their spiritual strength. Many also use this time to bear testimony of the church at a special church service held on the first Sunday of each month. They also give [at least] the money they saved by their fast to the church which uses it for support of the poor. In addition, Latter-Day Saints may also fast and pray voluntarily for a full 24 or 48 hours when they feel that they need extra spiritual strength or guidance. Like Muslims, they refrain from all drinking and eating unless they are small children or are physically unable to fast; for example, diabetics are not expected to fast. Fasting is also a characteristic of religions such as Hinduism, Buddhism and Jainism. Mahayana traditions that follow the Brahma's Net Sutra may recommend that the laity fast "during the six days of fasting each month and the three months of fasting each year". Members of the Baháʼí Faith observe a Nineteen-Day Fast from sunrise to sunset during March each year.

Baháʼí Faith

In the Baháʼí Faith, fasting is observed from sunrise to sunset during the Baháʼí month of ʻAlaʼ (1 or 2 March – 19 or 20 March). Baháʼu'lláh established the guidelines in the Kitáb-i-Aqdas. It is the complete abstaining from both food and drink during daylight hours (including abstaining from smoking). Consumption of prescribed medications is not restricted. Observing the fast is an individual obligation and is binding on Baháʼís between 15 years (considered the age of maturity) and 70 years old. Exceptions to fasting include individuals younger than 15 or older than 70; those suffering illness; women who are pregnant, nursing, or menstruating; travellers who meet specific criteria; individuals whose profession involves heavy labor and those who are very sick, where fasting would be considered dangerous. For those involved in heavy labor, they are advised to eat in private and generally to have simpler or smaller meals than are normal. Along with obligatory prayer, it is one of the greatest obligations of a Baháʼí. In the first half of the 20th century, Shoghi Effendi, explains: "It is essentially a period of meditation and prayer, of spiritual recuperation, during which the believer must strive to make the necessary readjustments in his inner life, and to refresh and reinvigorate the spiritual forces latent in his soul. Its significance and purpose are, therefore, fundamentally spiritual in character. Fasting is symbolic, and a reminder of abstinence from selfish and carnal desires."

Buddhism

Buddhist monks and nuns following the Vinaya rules regularly do not eat each day after the noon meal. This is not considered a fast but rather a disciplined regimen aiding in meditation and good health.

Once when the Buddha was touring in the region of Kasi together with a large sangha of monks he addressed them saying: I, monks, do not eat a meal in the evening. Not eating a meal in the evening I, monks, am aware of good health and of being without illness and of buoyancy and strength and living in comfort. Come, do you too, monks, not eat a meal in the evening. Not eating a meal in the evening you too, monks, will be aware of good health and..... living in comfort. Fasting is practiced by lay Buddhists during times of intensive meditation, such as during a retreat. During periods of fasting, followers completely stay away from eating animal products, although they do allow consumption of milk. Furthermore, they also avoid eating processed foods and the five pungent foods which are: garlic (Allium sativum), Welsh onion (Allium fistulosum), wild garlic (Allium oleraceum), garlic chives (Allium tuberosum), and asafoetida ("asant", Ferula asafoetida). The Middle Path refers to avoiding extremes of indulgence on the one hand and self-mortification on the other. Prior to attaining Buddhahood, prince Siddhartha practiced a short regime of strict austerity and following years of serenity meditation under two teachers which he consumed very little food. These austerities, undertaken alongside five other ascetics did not lead to progress in meditation, liberation (moksha), or the ultimate goal of nirvana. Henceforth, prince Siddhartha practiced moderation in eating which he later advocated for his disciples. On Uposatha days, roughly once a week, lay Buddhists are instructed to observe the eight precepts which includes refraining from eating after noon until the following morning. The eight precepts closely resemble the ten vinaya precepts for novice monks and nuns. The novice precepts are the same with an added prohibition against handling money. The Vajrayana practice of Nyung Ne is based on the tantric practice of Chenrezig. It is said that Chenrezig appeared to an Indian nun who had contracted leprosy and was on the verge of death. Chenrezig taught her the method of Nyung Ne in which one keeps the eight precepts on the first day, then refrains from both food and water on the second. Although seemingly against the Middle Way, this practice is to experience the negative karma of both oneself and all other sentient beings and, as such is seen to be of benefit. Other self-inflicted harm is discouraged.

Worked examples

Example 1 — a first encounter with Religious fasting

Start with the simplest possible case. Write down what Religious fasting claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Religious fasting before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Religious fasting ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Religious fasting

In research
Religious fasting appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Religious fasting in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Religious fasting is common in secondary-school and first-year university syllabi. It links to neighbouring topics Diets, Fasting, Religious fasting, so understanding it makes those chapters shorter.
In everyday life
Look for Religious fasting outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
