What is this wave which breaks upon the shore Of my ageing mind washing it so clear That nothing remains, no single line or mark To prove that a second past a thought was there A name, a person now forgotten, swept Backwards by the tide into a vast ocean Where it is tumbled until that certain force Drives it forward once more upon the beach Where I walk slowly filled with inward fear That what my memory’s lost I may not see Before the next wave, surging forward Obliterates all in its driving thrust – Yet still I stoop, hoping on that sand to find A shell of thought, a wrack of my own mind.
