My name should not be made prominent. It is my ideas that I want to see realized. The disciples of all the prophets have always inextricably mixed up the ideas of the Master with person, and at last killed the ideas for the person.The disciples of Sri Ramakrishna must guard against doing the same thing. Work for the idea, not the person.
-Swami Vivekananda
