No matter how carefully sand is raked, it will change, dissolve and disappear. This is also true of the backdrop against which our lives are performed. Life is impermanence. People, places, material possessions, good times, bad times: Everything changes. But this too, of course, is the nature of sand. Without its fluidity and ability to mould itself into new shapes, sand would not be sand. Without its fluidity and its ability to adapt, life would not be life. The sand can accept new shapes only because of its fluidity – the thing which gives it impermanence also breaths life into it.
If sand were fixed, like rock, it could not adapt or harmonise with its surroundings. It would become increasingly inappropriate as the scenery changed. Life too can be much like this. If we are too inflexible, we cannot flow and adapt: We cannot mutate to continue to harmonise with the changing environment of our lives. But some might say that even though a rock may be inflexible and not able to harmonise with its surroundings effectively, at least it is permanent. Not so. All sand was once supposedly permanent, immovable rock. Time will simply not allow permanence, so even although some things may seem so from our limited perspective, they are not and can never be.
