Keep a grateful journal. Every night, list five things that happened this day that you are grateful for. What it will begin to do is change your perspective of your day and your life. If you can learn to focus on what you have, you will always see that the universe is abundant; you will have more. If you concentrate on what you don't have, you will never have enough.
The only faults considered grave are the following: not respecting the rights of one's neighbor, letting oneself be paralyzed by fear, feeling guilty, thinking one does not deserve the good and bad which occurs in life, and being a coward.
The delights of this life are not its own, but our fear of the ascent into a higher life; the torments of this life are not its own, but our self-torment because of that fear.
