Fasting in the full-month of Ramadan every year teaches restraint by experiencing it. It brings humility, discipline, restraint, self-control and social consciousness about issues of hunger and deprivation. It is more powerful to share a state of being for the whole month in restraint than an hour of lighting out. It encourages solidarity and pro-social behaviour.

An illuminating, enlightening and informative book cannot be valued just by measuring the cost of pages, printing and binding.
