The Vedanta teaches men to have faith in themselves first. As certain religions of the world say that a man who does not believe in a Personal God outside of himself is an atheist, so the Vedanta says, a man who does not believe in himself is an atheist. Not believing in the glory of our own soul is what the Vedanta calls atheism.
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 VivekanandaKnow for certain that there is no power in the universe to injure us unless we first injure ourselves.
Swami VivekanandaWho will bring light to the poor? Who will travel from door to door bringing education to them? Let these people be your God-think of them, work for them, pray for them incessantly. The Lord will show you the way.
Swami VivekanandaWe say that if a temple, or a symbol, or an image helps you to realize the Divine within, you are welcome to it. Have two hundred images if you like. If certain forms and formulas help you to realize the Divine, God speed you; have, by all means, whatever forms, temples, whatever ceremonies you want to bring you nearer to God. But do not quarrel about them; the moment you quarrel, you are not going Godward, you are going backward towards the brutes.
Swami Vivekananda
