The world is your mirror: if you judge others, you will see others as judging you. If you withhold from others, you will see others as withholding from you.
The magic spell for conquering this mirror-world is to forgive with your whole heart what was never done to you in the first place. (The problem was never out there.) There is nothing about this that can't be done in an instant. Can we prepare to be as innocent as babies?
Forgive completely, like it never happened. Be as kind as you can, and more. Don't dwell on the apparent faults of others. The world is your mirror, so what do you have to lose?
