When people see some things as beautiful,
other things become ugly.
When people see some things as good,
other things become bad.

Being and non-being create each other.
Difficult and easy support each other.
Long and short define each other.
High and low depend on each other.
Before and after follow each other.

Therefore the Master
acts without doing anything
and teaches without saying anything.
Things arise and she lets them come;
things disappear and she lets them go.
She has but doesn’t possess,
acts but doesn’t expect.
When her work is done, she forgets it.
That is why it lasts forever.

Sooner or later we all discover that the important moments in life are not the advertised ones, not the birthdays, the graduations, the weddings, not the great goals achieved. The real milestones are less prepossessing. They come to the door of memory unannounced, stray dogs that amble in, sniff around a bit and simply never leave. Our lives are measured by these. 

– Susan B. Anthony  

Reason is man’s faculty for grasping the world by thought, in contradiction to intelligence, which is man’s ability to manipulate the world with the help of thought. Reason is man’s instrument for arriving at the truth, intelligence is man’s instrument for manipulating the world more successfully; the former is essentially human, the latter belongs to the animal part of man.

– Erich Fromm
