The clouds of shining whiteness, exhausted of their watery wealth, deserted the sky like the wise who have acquired wisdom, departing from their home. Evaporated by the rays of the autumnal sun, the lakes were dried up, like the hearts of men withered by the contact of selfishness. The silent waters of the autumn were beautified by white water-lilies, like the minds of the pure by the perception of truth.

In plain words: White clouds emptied of rain left the sky, like wise people leaving home after finding wisdom. Lakes dried up in the sun, like hearts dried up by selfishness. Still waters filled with white lilies, like pure minds that see the truth.
