If one is dissatisfied and disappointed with the material world, it is in part because it is not supposed to satisfy and appoint.
That's not what it's there for.
If you're bored on the train, it's probably because you're not aware there's supposed to be a destination and you're supposed to actually get out and explore the real place beyond one of the stations.
Trotting up and down the Cross-Pennine Chopper with a sausage in a box is a far cry from roving the wilds of the Peak District.
Seeking satisfaction for the self, directly from material things (even 'spiritualised' material things, like a 'sense of achievement' from a so-called career), is doomed to fail.
The purpose of the milkmaid's bucket is to have something to milk the cow into.
If one doesn't know what it's there for, one might put the bucket on one's head, or walk around putting cowpats in and wondering what all the fuss is about.
Living in abysmal ignorance of the real purpose of a life is not blameworthy, but at some point one has to climb out of the abyss.
If one does not know how to, one can always cry out of the abyss, and someone will hear you.
