Desire itself is movement
Not in itself desirable;
Love is itself unmoving,
Only the cause and end of movement,
Timeless, and undesiring
Except in the aspect of time
Caught in the form of limitation
Between un-being and being.
Gravitation cannot be held responsible for people falling in love. How on earth can you explain in terms of chemistry and physics so important a biological phenomenon as first love? Put your hand on a stove for a minute and it seems like an hour. Sit with that special girl for an hour and it seems like a minute. That's relativity.
A myriad of men are born; they labor and sweat and struggle; ...they squabble and scold and fight; they scramble for little mean advantages over each other; age creeps upon them; infirmities follow; ...those they love are taken from them, and the joy of life is turned to aching grief. It comes at last--the only unpoisoned gift earth ever had for them--and they vanish from a world where they were of no consequence, ...a world which will lament them a day and forget them forever.
I love you like a river that creates the right conditions for trees and bushes and flowers to flourish along its banks. I love you like a river that gives water to the thirsty and takes people where they want to go.
