All the powers in the universe are already ours. - Swami Vivekananda

A fool may buy all the books in the world, and they will be in his library; but he will be able to read only those that he deserves to.

Later on we read what Krishna says, “Even those who worship other deities are really worshipping me” (note 31). It is God incarnate whom man is worshipping. Would God be angry if you called Him by the wrong name? He would be no God at all! Can’t you understand that whatever a man has in his own heart is God — even if he worships a stone? What of that! We will understand more clearly if we once get rid of the idea that religion consists in doctrines. One idea of religion has been that the whole world was born because Adam ate the apple, and there is no way of escape. Believe in Jesus Christ — in a certain man’s death! But in India there is quite a different idea. [There] religion means realisation, nothing else. It does not matter whether one approaches the destination in a carriage with four horses, in an electric car, or rolling on the ground. The goal is the same. For the [Christians] the problem is how to escape the wrath of the terrible God. For the Indians it is how to become what they really are, to regain their lost Selfhood. ...

You find in Krishna that non-attachment is the central idea.
