There are a large number of religious establishments ["convents "] which they call khanqahs, and the nobles vie with one another in building them. Each of these is set apart for a separate school of darwishes, mostly Persians, who are men of good education and adepts in the mystical doctrines. Each has a superior and a doorkeeper and their affairs are admirably organized. They have many special customs one of which has to do with their food. The steward of the house comes in the morning to the darwishes, each of whom indicates what food he desires, and when they assemble for meals, each person is given his bread and soup in a separate dish, none sharing with another. They eat twice a day. They are each given winter clothes and summer clothes, and a monthly allowance of from twenty to thirty dirhams. Every Thursday night they receive sugar cakes, soap to wash their clothes, the price of a bath, and oil for their lamps. These men are celibate; the married men have separate convents.
Ibn Battuta
And this is probably a good place for me to end by just saying that the issue of climate change is a perfect example of why young people have to lead. Because old people, they've created a mess, and then they'll be gone. And then you -- (applause) -- you're the ones who have to deal with it. And also what happens is old people get set in their ways. So the older you get, the more likely you are to say, that's how it's always been so that's how I'm going to keep on doing it -- even if there's a better way to do things. Young people, they're asking, well, why do I have to do it that way? Let's try it this way. And that kind of willingness to accept challenges and try things in a new way, to not be stuck in the past, or to look towards the future, that's what all of you represent.
