Manual of the Warrior of light

I am finding the above book to be really good. I have been re-reading the the following passage over and over again.

Every warrior of light has felt afraid of going into battle

Every warrior of light has, at some time in the past, lied or betrayed someone

Every warrior of light has trodden a path that was not his

Every warrior of light has suffered for the most trivial of reasons

Every warrior of light has, at least once, believed that he was not a warrior of light

Every warrior of light has failed in his spiritual duties

Every warrior of light has said 'yes' when he wanted to say 'no'

Every warrior of light has hurt someone he loved

That is why he is a warrior of light, because he has been through all this and yet has never lost hope of being better than he is
