'Mans does not live by bread alone' is an old saying which simply defines that man needs much more than bread itself.
Here the word 'bread' stands for the primary or basic needs of life. In order to live man needs food, clothes and shelter.
But these are not enough. Man's life is not for fulfilling only these three needs. He has more and more wants in life and
for achieving them he does strenuous labour day and night. He makes impossible possible. It is here, that we find the
difference between man and animal. Animals also have these needs, and they can live if these needs are fulfilled. But man cannot.
He is different from the animals in having a mind and a soul as well. He has intellectual, emotional and spiritual needs which must be fulfilled instantly otherwise he will be half- dead. He- can live without bread for a day or two but not without satisfying his needs related to mind and soul. He requires mental food in addition to bread. He wants to study good books sometimes for pleasure and sometimes for gathering
knowledge on different subjects. He needs newspapers daily to know what is happening around him. He craves aesthetic satisfaction and finds immense pleasure in art and literature. There are scientists who work twenty four hours to achieve
their goals. They can not live without their scientific studies. A well known instance from Newton's life can easily explain
what really a man wants. While doing experiments in his laboratory Newton became so engrossed that he boiled his keys instead of eggs. He could live without eggs but not without his experiments, because they were his mental food.
Man has a heart which makes him emotional. He loves others and in turn wants to be loved. He craves for a family with a wife and children and maintains good relations with his kith and kin. He needs true friends. He wants to share his joys and sorrows with his family members, relatives and friends. Man has some spiritual needs too. He has a soul and he wishes to satisfy it by doing some noble' deeds. He extends a helping hand to those who are in distress. He wants to lead
a virtuous life. He prays to God for the welfare of the whole humanity. He has his conscience which he keeps awake all the time and tries to bring spiritual development, the essence of true happiness.
Thus man has numerous needs apart from his daily bread. Unless there needs are fulfilled he is not happy. He would like
to die even though enough bread is available.
