Warrior of the Light: A Manual (a birthday gift from my daughter) reads like a series of short devotionals for actual and spiritual warriors. My take is that author, Paulo Coelho, would say there is no difference between the two. Here is one from a couple of days ago that struck me.
First: God is sacrifice. Suffer in this life and you will be happy in the next.
Second: People who have fun are childish. Remain tense at all times.
Third: Other people know what is best for us because they have more experience.
Fourth: Our duty is to make other people happy. We must please them even if that means making major sacrifices.
Fifth: We must not drink from the cup of happiness; we might get to like it and we won't always have it in our hands
Sixth: We must accept all punishments. We are guilty.
Seventh: Fear is a warning. We don't take any risks.
These are the commandments that no Warrior of the Light can obey.
