“Give up the awful disease that is creeping into our national blood, that idea of ridiculing everything, that loss of seriousness. Give that up. Be strong and have this Shraddha, and everything else is bound to follow.”
“One of the difficulties in bringing about change in an organization is that you must do so through the persons who have been most successful in that organization, no matter how faulty the system or the organization is. To such persons, you see, it is the best of all possible organizations, because look who was selected by it ad look who succeeded most in it. Yet, these are the very people through whom we must bring about improvements.”
“Good reasons must of force give place to better.”
