“Knowledge is a most peculiar affair, especially for a warrior. Knowledge for a warrior is something that comes at once, engulfs him, and passes on.”

The Manual of the Warrior of Light (1997)
Context: Every Warrior of the Light has suffered for the most trivial of reasons. Every Warrior of the Light has, at least once, believed he was not a Warrior of the Light.
Every Warrior of the Light has failed in his spiritual duties.
Every Warrior of the Light has said "yes" when he wanted to say "no."
Every Warrior of the Light has hurt someone he loved.
That is why he is a Warrior of the Light, because he has been through all this and yet has never lost hope of being better than he is.
Each stone, each bend cries welcome to him. He identifies with the mountains and the streams, he sees something of his own soul in the plants and the animals and the birds of the field.
Then, accepting the help of God and of God's signs, he allows his personal legend to guide him toward the tasks that life has reserved for him.
On some nights, he has nowhere to sleep, on others he suffers from insomnia. "That's just how it is," thinks the warrior. "I was the one who chose to walk this path."
In these words lies all his power: He chose the path along which he is walking and so has no complaints.
