Thus Spake Swami Vivekananda
Each soul is potentially divine. The goal is to manifest this Divinity within, by controlling nature, external and internal. Do this either by work, or worship, or psychic control, or philosophy by one or more or all of these and be free. This is the whole of religion. Doctrines, or dogmas, or rituals, or books, or temples, or forms, are but secondary details.
In doing evil we injure ourselves and others also. In doing good we do good to ourselves and to others as well. According to Karma-Yoga, the action one has done cannot be destroyed until it has borne its fruit; no power in nature in nature can stop it from yielding its results. If I do an evil action, I must suffer for it; there is no power in this universe to stop or stay it. Similarly, if I do a good action, there is no power in the universe which can stop its bearing good results.
Never think there is anything impossible for the soul. It is the greatest heresy to think so. If there is sin, this is the only sin to say that you are weak, or others are weak.
Whatever you think, that you will be. If you think yourselves weak, weak you will be. If you think yourselves strong, strong you will be.
Be free; hope for nothing from anyone. I am sure if you look back upon your lives you will find that you were always vainly trying to get help from others which never came. All the help that has come was from within yourselves.
Never 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.
The remedy for weakness is not brooding over weakness, but thinking of strength. Teach men of the strength that is already within them.
To succeed, you must have tremendous perseverance, tremendous will. I will drink the ocean, says the persevering soul; at my will mountains will crumble up. Have that sort of energy, that sort of will; work hard, and you will reach the goal.
Let people say whatever they like, stick to your own convictions, and rest assured, the world will be at your feet. They say, Have faith in this fellow or that fellow, but I say, Have faith in yourself first, that's the way. Have faith in yourself all power is in you be conscious and bring it out. Say, I can do everything.Even the poison of a snake is powerless if you can firmly deny it.
