Sri Ramakrishna brought with him sixteen eternal companions to exemplify the different paths by which the Ultimate can be realized. The diligent steady of their lives will illumine our own progress in the spiritual field.
Take up one idea. Make that one idea your life -- think of it, dream of it, live on that idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success, and this is the way great spiritual giants are produced. Others are mere talking machines.
-Swami Vivekananda
