Like growing watermelons If heaven is merely an explanation which grew out of reflections on life and death, then whether or not there is a heaven appears unimportant, and indeed some people do not refer to heaven at all when explaining the world after death.
既然天堂只是探求生死延伸出來的解釋，由此來看，有沒有天堂不僅不重要，有人根本不用天堂解釋死後世界。
