And after you have achieved this, know that water is two waters, purifying water, distilled, of the utmost purity and purification, and it is the water of rain, for it is impossible water made of dense vapors. Distillation has removed whatever density was attached to it, and this is the worldly legal knowledge, for it is about exercise, struggle, and purification, so purify yourself with it for communion. Your Lord, the other water is water that has not reached this level of sweetness, and it is the water of springs and rivers. It springs from stones and is mixed according to the spot in which it springs and flows, so its taste differs. Some of it is sweet and bitter, some is salty, brackish, and some is bitter.
