Gravity

I look at nature and reflect on the existence in it of a force so silent and invisible that human beings were not aware of it till lately; and yet so mighty that the world is moved by it: the force of gravity.

Because of it the bird flies in the sky,
mountains are held in place, 
leaves flutter to the ground,
planets are kept in orbit.

There is no better symbol of God's power and presence.

Anthony de Mello in "Wellsprings" page 58
