The difference between God and the devil is in nothing except in unselfishness and selfishness. The devil knows as much as God, is as powerful as God; only he has no holiness that makes him a devil. Apply the same idea to the modern world: excess of knowledge and power, without holiness, makes human beings devils.
Swami VivekanandaI am not talking about what every one of us means by love. Little namby-pamby love is lovely. Man rails in love with woman, and woman goes to die for man. The chances are that in five minutes John kicks Jane, and Jane kicks John. This is a materialism and no love at all. If John could really love Jane, he would be perfect that moment.
Swami VivekanandaNever say, ‘No’, never say, ‘I cannot’, for you are infinite. Even time and space are as nothing compared with your nature. You can do anything and everything, you are almighty
Swami VivekanandaLet the mind be cheerful but calm. Never let it run into excesses, because every excess will be followed by a reaction.
Swami VivekanandaThe goal of mankind is knowledge ... Now this knowledge is inherent in man. No knowledge comes from outside: it is all inside. What we say a man 'knows', should, in strict psychological language, be what he 'discovers' or 'unveils'; what man 'learns' is really what he discovers by taking the cover off his own soul, which is a mine of infinite knowledge.
