On the banks of the Euphrates find a secret garden cunningly walled. There is an entrance, but the entrance is guarded. There is no way in for you. Inside you will find every plant that grows growing circular-wise like a target. Close to the heart is a sundial and at heart an orange tree. This fruit had tripped up athletes while others have healed their wounds. All true quests end in this garden, where the split fruit pours forth blood and the halved fruit is a full bowl for travellers and pilgrims. To eat the fruit means to leave the garden because the fruit speaks of other things, other longings. So at dusk you say goodbye to the place you love, not knowing if you can ever return, knowing you can never return the same way as this. It may be, some other day that you will open a gate by chance, and find yourself again on the other side of the wall.
