Ramadan in the Philippines began at the rise of the sun today. As of the moment and until 29 days later, each day from sun up till sun down, will be a day of denial of worldly pleasures. Such like food, water, alcohol and other things are avoided during daylight by the Islamic community as part of the practice of their religion.
Fasting is one of the Five Pillars of Islam. Just like any other religion, fasting is important but none prescribe and implement widespread practice of such like Islam. Fasting is a way to train oneself to be in control of mind and body, pushing it to the limits.
