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.
To be a saint is the exception; to be upright is the rule. Err, falter, sin, but be upright. To commit the least possible sin is the law for man. Sin is a gravitation.
Gravitation is not responsible for people falling in love.
A true man never frets about his place in the world, but just slides into it by the gravitation of his nature, and swings there as easily as a star.
