If you intend to study the mind, you must have systematic training; you must practice to bring the mind under your control, to attain to that consciousness from which you will be able to study the mind and remain unmoved by any of its wild gyrations. Otherwise the facts observed will not be reliable; they will not apply to all people and therefore will not be truly facts or data at all.
Swami VivekanandaI have come to deal with principles. I have only to preach that God comes again and again, and that He came in India as Krishna, Rama, and Buddha, and that He will come again. It can almost be demonstrated that after each 500 years the world sinks, and a tremendous spiritual wave comes, and on the top of the wave is a Christ.
Swami VivekanandaThe mistake is that we cling to the body when it is the spirit that is really immortal.
Swami VivekanandaThere is another way in which this idea of mercy and selfless charity can be put into practice; that is, by looking upon work as "worship" in case we believe in a Personal God. Here we give up all the fruits our work unto the Lord, and worshipping Him thus, we have no right to expect anything from man kind for the work we do.
Swami Vivekananda
