No one succeeds without effort... Those who succeed owe their success to perseverance.
In accordance with the prarabdha of each, the One whose function it is to ordain makes each to act. What will not happen will never happen, whatever effort one may put forth. And what will happen will not fail to happen, however much one may seek to prevent it. This is certain. The part of wisdom therefore is to stay quiet.
There is nothing so simple as being the Self. It requires no effort, no aid. One has to leave off the wrong identity and be in his (her) eternal, natural, inherent state.
