In spite of a life devoted to meditation, prayer and books, Brahmagupta was like many other monks I have come to know and admire who are perpetually cheerful, who laugh easily and loudly, the laughter not springing from a sense of humour but from an evolved spirit of mischief and playfulness. Sometimes, watching the frequent and obvious merriment of these monks, I have wondered whether the Buddha's message is indeed about the world being full of pain and sorrow; or perhaps, the Enlightened One has left a secret message for his monks, a cosmic joke which never palls with any number of re-tellings, which makes them laugh so much.
