Be like the pearl oyster. There is a pretty Indian fable to the effect that if it rains when the star Svati is in the ascendant, and a drop of rain falls into an oyster, that drop will become a pearl. The oysters know this, so they come to the surface when that star shines, and wait to catch the precious raindrop. When one falls into the shell, quickly the oyster closes it and dives down to the bottom of the sea, there to patiently develop the drop into the pearl. We should be like that. First hear, then understand, and then, leaving all distractions, shut our minds to outside influences, and devote ourselves to developing the truth within us.
