Love is the root of all other passions.
The wonderful depravity of our natural love. The only universal remedy is charity or Divine love. The which are never separated. But if it be present, then the effect of love is joy, rest, and fruition of it. Hence will appear how inexpressibly depraved both our nature and all our actions, outward and inward, must be, since whereas we were created only to love and enjoy God, yet we love and seek nothing but ourselves.
