Throughout our lives, we are busily shaping another body, so that when our work here has been completed and we have to leave it, we go to the other body that we have been preparing with our actions in this one. In other words, once all the results of our activities in previous lives that were destined for this body have been suffered or enjoyed, then it is time to leave it. We give up this body in great distress, but when it falls away here in this world, we leave it with our subtle body and enter another body.
