Plunge into the world, and then, after a time, when you have suffered and enjoyed all that is in it, will renunciation come; then will calmness come. So fulfill your desire for power and everything else, and after you have fulfilled the desire, will come the time when you will know that they are all very little things; but until you have fulfilled this desire, until you have passed through that activity, it is impossible for you to come to the state of calmness, serenity, and self-surrender.
Swami VivekanandaIf you have not even a little imagination, you are simply a brute. So you must not lower your ideal, neither are you to lose sight of practicality. We must avoid the two extremes.... You must try to combine in your life immense idealism with immense practicality.
Swami Vivekananda
