If not our minds, then what?

What do we have if not our minds? Any ownership we claim is fleeting Our possessions wither, wear, and decay Yet, we still cling to things in this world While our minds slip and fade. There is nothing so important as sanity Still we allow our thoughts to cloud and wither We become shadows of men and women Shades lost of wit and senses Until we fade into nothing I will not allow myself to fade My mind will not collapse My thoughts will stay sharp My wit is strong, honed and sharp Can you say the same? Or do you cling hopelessly to your things? While they weather away into dust And your minds last thoughts come to pass In the end you will know You sacrificed clarity for fleeting bliss Your mind is gone and you have naught left For what do you have if not your mind? An abyss in which your joys will cringe and die As your mindless shell joins your possessions In death
