From childhood, I felt a compassion for animals. Even before I started
school, I found it impossible to understand why, in my evening prayers,
I should pray only for human beings. Consequently, after my mother
had prayed with me and had given me a good-night kiss, I secretly
recited another prayer, one I had composed myself. It went like this:

Dear God, protect and bless all living beings.
Keep them from evil and let them sleep in peace.
