'Everything we do, everything we are, rests on our personal power. If we have enough of it, one word uttered to us might be sufficient to change the course of our lives. But if we don't have enough personal power, the most magnificent piece of wisdom can be revealed to us and that revelation won't make a damn bit of difference.'
From Tales of Power
Thus, the 'secret protects itself' as we are our own protectors. We must increase our necessity for change.
