Spirit is what informs one. Material interests, information, data all emanate from human spirit. One has the freedom to choose what spirits inform. Choose malevolent spirits, anger, complaint consumes, choose good spirit, experience a more measured mind.
Wisdom is good spirit, knowledge only elementary. Having the widest possible perspective is what wisdom seeker after. Having only self perspective is blind man, everything zero sum game. One can only gain wisdom with courage, fear closes doors, courage opens.
And its not enough to merely read the words and digest facts, one must encounter the spirit, in other words be empathetic to those with differing perspectives. Intention then becomes known, spirit drives intention, intention is the spirit.
So much conflict created by misjudging intention. Understanding intention or keeping mindful one may not know another's intent will help mediate one's reaction.
Some say love is greatest lacking in world, I've always thought empathy greatest lacking.
