Peace without knowledge of the cause of that peace is still ignorance.

The tree of knowledge is based on pleasure and pain; the ultimate reduction. From here we get joy and sorrow, the two primary emotions. Love is a form of joy and hate, a form of sorrow, but all spring from the tree of pleasure and pain, which all 'know.

Exchange the burden of the world, for the peace of God.

A worried mind has forgotten God

God is the cause that is 'cause of itself' (essence) and the Universe is the effect existing within the cause (existence). Essence involves existence.
