As a time to purify the soul, refocus attention on God, and practice self-sacrifice, Ramadan is much more than just not eating and drinking.

Muslims are called upon to use this month to re-evaluate their lives in light of Islamic guidance. They are to make peace with those who have wronged them, strengthen ties with family and friends, do away with bad habits -- essentially to clean up lives, thoughts, and feelings.

The Arabic word for "fasting" (sawm) literally means "to refrain" - and it means not only refraining from food and drink, but from evil actions, thoughts, and words.
