"A challenge is an opportunity for progress" because:
1) A challenge is not just a problem
2) A challenge is a difficulty that carries within it an opportunity for progress
3) Once we overcome a challenge we go up to a higher level than before
4) Legal challenges alone cannot overcome challenges to democracy like inequality, poverty, unemployment illiteracy, regionalism, casteism, communalism etc.
5) Legal constitutional changes and the cooperation of the citizen is the need of the hour.
