I believe that it's important to do our very best to know what will happen to us after this life (if anything happens to us). If we go somewhere, it would seem to be of paramount importance to know where that somewhere will be because eternity is a loooooong time. On the other hand, since there are many contradictory opinions about this subject, I find great solace and comfort in what the Buddha allegedly taught about this subject. He said:
"If there is a world after death, if there is the fruit of actions rightly & wrongly done, then this is the basis by which, with the break-up of the body, after death, I will reappear in a good destination, the heavenly world.’ This is the first assurance [a man who follows the teachings] acquires.
"But if there is no world after death, if there is no fruit of actions rightly & wrongly done, then here in the present life I look after myself with ease — free from hostility, free from ill will, free from trouble.’ This is the second assurance [a man who follows the teachings] acquires." (Kalama Sutta, AN 3.65)
Thus, I have some certainty that if there is another world after this one, I will be blessed, because I do my very best to live a good and a compassionate life here, and because I search for the truth to my very best of my ability. If there is a God that is worthy of my worship, He or She will reward my efforts. If there is no life after this one then my efforts, and my search, are of value in and of themselves, because they help me to live a better life here and now, and because they bring me joy in the search, here and now.
Either way, the path, the journey, and the search are well worth the effort.
