No gods doesn't have that power. they are only joying the result of their good karma.. after that they will come back to the human world and start collecting karma for another birth it depends on their karma.. this is the cycle If someone stop collecting karma in their mind and the physical body they are not going to birth again.. you see karma is the thing that bind us to cycle.. if the cycle stopped ... that the thing called nirvana.. never born again.. Now you can say why stopping the cycle?? being on the cycle is hard.. there is sorrow , there is happiness, illness and death.. do you ever feel the emptiness that brought from the farewell someone you really care about.. There are somethings you badly want.. You try hard to get them but you can't.. if you got them what after that .. We all try for another one.. always.. until our death.. what after that?? In our religion we born again according to karma.. yours I think you might go to the heaven or hell according to the karma.. Sorry if I wrong... What the point?? eternal soul... eternal bond with the cycle.. our religion says until you figure out how to stop karma do good things earn karma to do so.. Its not about the leaving your loved ones behind.. if you study buddhism you will learn a great love story... Don't misunderstand me.. I am not insulted any religion.. I Just want to reduce the misunderstanding.. thank you very much
