The Vedanta recognises no sin it only recognises error. And the greatest error, says the Vedanta is to say that you are weak, that you are a sinner, a miserable creature, and that you have no power and you cannot do this and that.
The mind is like an elastic band. The more you pull, the more it stretches. The mind-elastic will never break. Every time you feel limitations, close your eyes and say to yourself, 'I am the Infinite,' and you will see what power you have.
