For the religion of Islam, it is now the holy month of Ramadan, which in its essence is a major fast observed by 1 billion Muslims throughout the world. People typically undergo the purification ritual of fasting as a means to cleanse the spirit, body or both. All major religions throughout the world including Christianity, Buddhism, Judaism, Hinduism, and Islam involve some variation of fasting into their religious code of practice. Native American tribes also practice a fast paired with a guided meditation as part of a spiritual ritual. Plainly stated, fasting is the act of intentional abstinence from food and water during a specified period of time, but when done mindfully or with a spiritual purpose, it becomes much more.
