And when the gardens cannot exist except with rivers, he said: "In them are two springs." This means: in each one is a spring that flows in every place its owner desires, even if its location is high, just as water rises in trees in every branch of them. And if its height increases, it flows upon the two eyes of his tears that flow from the fear of Allah. And this is similar to the gardens of this world. And the sun rises in the northern constellations from the abundance of water and the bursting forth of springs in the days of spring and summer due to the recent rains.
