Ideals vary with regard to everything. So every man has his own ideal of human greatness. Some worship the man of power, some look up for inspiration to the silent, patient worker, who is dedicated to knowledge, trying to keep the torch of science and philosophy burning like Einstein, C. V. Raman or Satyen Bose. There are others, again, who love the man of action, the doer of deeds as Stalin in Russia or Netaji Subhas Ch. Bose in India and outside. And there may be others also, who are impressed by the man who obeys the inner call and renounces the world and dedicates himself to duties of love and service, like Swami Vivekananda.
