The ruling power within, when it is in its natural state, is so related to outer circumstances that it easily changes to accord with what can be done and what is given it to do.

Purge your mind of all aimless and idle thoughts, especially those that pry into the affairs of others or wish them ill.

It is the duty of men to love even those who injure them.
