Book Two, Chapter 4
Of a Pure Mind and a Simple Intention

By two wings is man lifted above earthly things, viz., by simplicity and purity.  Simplicity must be in the intention, purity in the affection.  Simplicity aims at God, purity apprehends Him and tastes Him....If there is joy in the world, truly the man of pure heart possesses it.  And if there be anywhere tribulation and distress, an evil conscience the more readily experiences it.
