Let the mind be cheerful but calm. Never let it run into excesses, because every excess will be followed by a reaction.
Swami VivekanandaThis world, this universe which our senses feel, or our mind thinks, is but one atom, so to say, of the Infinite, projected on to the plane of consciousness; and within that narrow limit, defined by the network of consciousness, works our reason, and not beyond. Therefore, there must be some other instrument to take us beyond, and that instrument is called inspiration.
Swami VivekanandaThought is like a bubble rising to the surface. When thought is joined to will, we call it power. That which strikes the sick person whom you are trying to help is not thought, but power.
Swami Vivekananda
