The main thing is this: we should never blame anyone or anything for our defeats. No matter how evil their intentions may be, they are altogether unable to harm us until we begin to blame them and use them as excuses for our own unbelief.
Change is always subjective. All through evolution you find that the conquest of nature comes by change in the subject. Apply this to religion and morality, and you will find that the conquest of evil comes by the change in the subjective alone. That is how the Advaitic system gets its whole force, on the subjective side of man.
I had learned to dwell with pleasure as a beloved daydream on the thought of the separation of these elements. If each I told myself could be housed in separate identities life would be relieved of all that was unbearable the unjust might go his way delivered from the aspirations and remorse of his more upright twin and the just could walk steadfastly and securely on his upward path doing the good things in which he found his pleasure and no longer exposed to disgrace and penitence by the hands of this extraneous evil.
