Live for an ideal, and that one ideal alone. Let it be so great, so strong, that there may be nothing else left in the mind; no place for anything else, no time for anything else.
Swami VivekanandaWe must have friendship for all; we must be merciful toward those that are in misery; when people are happy, we ought to be happy; and to the wicked we must be indifferent. These attitudes will make the mind peaceful.
Swami VivekanandaPlunge 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 Vivekananda
