Q4. Read the passage given below and answer the questions that follow — [RAS Mains 2021]
The thoughtless, the ignorant and the indolent, seeing only the apparent effect of things and not the things themselves, talk of luck of fortunes and chance. Seeing a man grow rich they say “How lucky he is!” Observing another become intellectual they exclaim, “How highly favoured he is!” And noting the saintly character and wide influence of someone else they remark, “How chance aids him at every turn!” They do not see the trials and failures and struggles which these men have voluntarily encountered in order to gain their experience, have no knowledge of the sacrifices they have made, of the undaunted efforts they have put forth, of the faith they have exercised that they might overcome the apparently insurmountable and realise the vision of their heart. They do not know the darkness and the heartaches, they only see the light and joy; do not see the long and arduous journey but only behold the pleasant goal and call it “good fortune”; do not understand the process but only perceive the results and call it ‘Chance’.
In all human affairs there are efforts and there are results and the strength of effort is the measure of the result. Chance is not. Gifts, powers, material, intellectual and spiritual possessions are the fruits of effort — they are thoughts completed, objects accomplished, visions realised.
