CAT 2023 Reading Comprehension — Previous Year Question

All the great religious teachers of mankind have insisted on this: that men ought not to live for themselves alone. We ought not, they have said, to spend all our time and energy in getting just what we want for ourselves, power and money and importance in the world; we ought to serve something greater than ourselves, whether a god or a cause or our fellowmen. It is by serving this something greater that men will forget themselves and so achieve happiness. This or something like it is what the great religions have taught, and it is one of the most important of the things that civilization means. It is also the hardest to learn and practise; in fact, most people have found it much too hard.
