Subtlety

Human subtlety will never devise an invention more beautiful, more simple or more direct than does nature because in her inventions nothing is lacking, and nothing is superfluous.
-Leonardo da Vinci

Questions show the mind's range, and answers, its subtlety.
-Joseph Joubert

He is inside as well as outside all beings, animate and inanimate. He is incomprehensible because of His subtlety. He is very near as well as far away.
-Bhagavad Gita
