No doubt one day soon, if it hasn't already happened, someone will have a religious experience while in Second Life. Think of the advantages of being able to pray and worship with other religious Second Life inhabitants as opposed to going to a brick and mortar church down the street or in another part of town.
A temple, church or mosque inside of Second Life has no screaming children. People do not cough or sneeze uncontrollably while they are in Second Life. If they do, they are behaving in an affected manner by imitating Real World peculiarities. In a Second Life religious environment there is the familiarity of your own home, because technically you are still in your own home. Of course, if you log-on from your laptop, your environment can be anywhere you wish it to be: in a plane, on the beach at dawn, in a quiet garden, in an ancient library surrounded by even older forests.
If you are not able to kneel in the Real World, your Second Life avatar can kneel for you for as long as you wish to continue kneeling in the house of worship of your choice.
Perhaps when it becomes possible to upload personalities and memories successfully, people will, in fact, live out their lives, or continue a kind of virtual life-after-death inside of Second Life.
