Which Robert Pirsig quotes did you mean again? That link seems to be for this article itself.
“The real cycle you're working on is a cycle called yourself.”
“Like those in the valley behind us, most people stand in sight of the spiritual mountains all their lives and never enter them, being content to listen to others who have been there and thus avoid the hardships.”
These talk a little bit about self-improvement, or that knowledge is not understanding. Telling someone that new relationships aren't going to help, that acquiring new stuff won't help, is just giving them your personal knowledge/wisdom but you can't give them understanding.
