NEVER THINK THERE IS ANYTHING IMPOSSIBLE FOR THE SOUL. IT IS THE GREATEST HERESY TO THINK SO

This, says the Vedanta, is the ideal to follow. Every one of us will have to become a prophet, and you are that already. Only know it. 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.
