FASTING

Fasting is one of those things that are driven by the very nature of humans. As Maslow's pyramid of needs classify it hunger is a very big motivator in human behavior. When a person is pre-occupied by hunger he is given the opportunity to think and contemplate spiritual matters. Also it gives people the opportunity to feel the misery of hunger that the less fortunates endure.
Economically speaking it is also a mean by which expenditure can be reduced. Fasting has also been shown to have positive medical effects.
