We find ourselves in a universe pervaded by laws that define the relationship of action and consequence. Some are manmade: speed and you get a ticket; rob and you go to jail; break curfew and you're grounded.  Some are physical: let go of a rock and it drops; expose potassium to air and it forms hydrogen gas; mix baking soda and vinegar and you get a frothing pot worthy of the witch's concoction in Shakespeare's Macbeth.  And some laws are moral: nurturing hatred cankers the soul; practicing kindness and forbearance develops serenity.

Parents and police officers alert us to the first category.  Physicians and chemists may give us fluency in the second.  But nothing short of trial and error will convert us to the unyielding strictures of the third.  To be adept at the first entails outward behavior.  Mastering the second challenges our mind.  but to live in harmony with the moral law of the universe requires body and soul, heart and mind, the will and the affections of the undivided self.  This is the meaning of Jesus' words that living the highest and holiest law; loving God, requires "all your heart, and...all your soul, and...all your mind."
