Why are we here?' 'To make more love.' 'All right, fair enough. But how do we best love this world Allah gave us? We do it by learning it! [...] If you try to understand things, if you look at the world and say, why does this happen, why do things fall, why does the sun come up every morning and shine on us, and warm the air and fill the leaves with green--how does all this happen? What rules has Allah used to make this beautiful world?--Then it is all transformed. God sees that you appreciate it. And even if He doesn't, even if you never know anything in the end, even if it's impossible to know, you can still try. [...] This is God's real work.
