After counting out the signs in the heavens and on the earth, the Qur'an suddenly turns its word to the human breast.
The nearest verse is the one read last.

Man searches for meaning among the stars, descends to the ocean floor, climbs to the mountain's peak; yet he never looks at the rise and fall of his own breath.
The question at the end of the verse is not a reproach but an awakening: the door of the treasure opens where you look the least.
