The mind that is untroubled and tranquil has the power to roam into all the parts of its life; but the minds of the engrossed, just as if weighted by a yoke, cannot turn and look behind. And so their life vanishes into an abyss; and as it does no good, no matter how much water you pour into a vessel, if there is no bottom to receive and hold it, so with time — it makes no difference how much is given; if there is nothing for it to settle upon, it passes out through the chinks and holes of the mind.
