7 years' professional training as a scientist, I questioned my religion: Does the circle of life really exist? We die and become organic compounds. We don't own anything any more. What do we have except for a headstone and some teddy bears ? We may not enter next life as Buddha told us, but those organic compounds fertilize grasses generating oxygen for our sons and their sons. That's how we live forever. This might be the next life Buddhism is referring to.
