Bhagat Singh said this quote

“ The aim of life is no more to control the mind, but to develop it harmoniously; not to achieve salvation here after, but to make the best use of it here below; and not to realise truth, beauty and good only in contemplation, but also in the actual experience of daily life; social progress depends not upon the ennoblement of the few but on the enrichment of democracy; universal brotherhood can be achieved only when there is an equality of opportunity - of opportunity in the social, political and individual life.— from Bhagat Singh's prison diary, p. 124 ”
