And enlightened people DO have fun, but they don't seek it from a position of want and need...the way the monkey mind constantly does. It's the monkey mind that keeps me coming back to this forum, but I try to seek enlightenment at the same time. It's an interesting process to observe, but a very hard one to control.
I consider Jesus, Buddha, and Krishna to have been very enlightened beings, and there have been many others. Most of them moved quietly through the World and were not been remembered by history at all. That is also the way of a Taoist master. He/she usually does not attract people's attention but passes by without notice, being in perfect harmony with the World. It's those who are seriously out of harmony who attract attention, usually, but an enlightened person can take on a special task in the World, as Jesus did, as Buddha did, in which case he is doing it as an act of mercy to help take others TO enlightenment and free them from suffering...NOT to found yet more churches and religious orders with yet more rules to follow.
