[/quote] Does anyone else have a reason to believe in rebirth?[/quote]
I don't have any reason to "believe" in rebirth but I have reasons to live as if it were true. It is a three dimensional model of cause and effect. Every physical, verbal and mental action has an effect in this life and/or beyond this life. I think arguing about literal truth or falshood of rebirth may miss the point. It is not scientific but it is extremely useful to me.
Happy, at rest,
may all beings be happy at heart.
Whatever beings there may be,
weak or strong, without exception,
seen & unseen,
near & far, born & seeking birth: May all beings be happy at heart.
Let no one deceive another
or despise anyone anywhere,
or through anger or irritation
wish for another to suffer.
