A Message on the Nature of Love

I asked - may God make you happy - O Abu Abdullah, the infallible jurist, that I should compile for you a letter containing clarification of what is said about love for the sake of brevity, so I asked you - I am still a seeker of good things - out of the desire to please you and fulfill your needs, and I made my letter to you included seven chapters:
One of them: in mentioning the flow of the power of love into every one of the identities.
The second: in mentioning the existence of love in simple, inanimate essences.
Third: In mentioning the existence of love in beings that have nourishing powers in terms of their nourishing powers.
The fourth: in mentioning the existence of love in animal essences insofar as they have animal power.
Fifth: In mentioning the love of cute people and boys for beautiful faces.
Sixth: In mentioning the love of divine souls.
Seventh: At the end of the chapters.
