Don't imagine that your perfection lies in accumulating or possessing external things. Your affection is inside of you. If only you could realise that, you would not want to be rich. Ordinary riches can be stolen from a man. Real riches cannot. In the treasury-house of your soul, there are infinitely precious things, that may not be taken from you. And so, try to so shape your life that external things will not harm you. And try also to get rid of personal property. It involves sordid preoccupation, endless industry, continual wrong. Personal property hinders Individualism at every step.
