Power of Thinking

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; if you think yourselves impure, impure you will be; if you think yourselves pure, pure you will be. This teaches us not to think ourselves as weak, but as strong, omnipotent, omniscient.
-Swami Vivekananda

Build the Body

First you have to build the body by good nutritious food -- then only will the mind be strong. The mind is but the subtle part of the body.The only test of good things is that they make us strong.As soon as you say,"I am a little mortal being," you are saying something which is not true, you are giving the lie to yourselves, you are hypnotising yourselves into something vile and weak and wretched.
-Swami Vivekananda
