When we cast our bread upon the waters we can presume that someone downstream whose face we will never know will benefit from our action, as we who are downstream from another will profit from the grantor's gift.
We can make our minds so like still water that beings gather about us that they may see, it may be, their own images, and so live for a moment with a clearer, perhaps even with a fiercer life because of our quiet.
Water is a commodity not by any means to be found everywhere...When found, it is more than likely to be bad, being either from a bitter alkaline pool, or from a hole in a creek, so muddy that it can only be called liquid by courtesy.
