Pythagoras asks that we not let a friend go lightly, for whatever reason. Instead, we should stay with a friend as long as we can, until we're compelled to abandon him completely against our will. It's a serious thing to toss away money, but to cast aside a person is even more serious. Nothing in human life is more rarely found, nothing more dearly possessed. No loss is more chilling or more dangerous than that of a friend.
With what a deep devotedness of woe I wept thy absence - o'er and o'er again Thinking of thee, still thee, till thought grew pain, And memory, like a drop that, night and day, Falls cold and ceaseless, wore my heart away!
The many great gardens of the world, of literature and poetry, of painting and music, of religion and architecture, all make the point as clear as possible: The soul cannot thrive in the absence of a garden. If you don't want paradise, you are not human; and if you are not human, you don't have a soul.
Let me define a garden as the meeting of raw nature and the human imagination in which both seek the fulfillment of their beauty. Every sign indicates that nature wants us and wishes for collaboration with us, just as we long for nature to be fulfilled in us. If our original state was to live in a garden, as Adam and Eve did, then a garden signals our absolute origins as well as our condition of eternity, while life outside the garden is time and temporality.
