A good word is ABSTINANCE. You train yourself for self restraint.
One method is not eating whilst active in your daily duties; Ramadan training.
One method is avoiding confrontation, restraining yourself until the truth manifests itself; Mary and Zakharia.
Not eating and drinking, something that is natural and a necessity, should build your character. Because the majority do not do this but indulge in gluttony when ending daily
fasts does not make for 'no fasting' in the same way we do not get rid of the Quran because the majority just read it like parrots with no understanding.
