For me one of the most important aspects of theistic religion is that it provides a purpose to life and something to work toward. When you take away an afterlife, it makes life seem so meaningless and all the things you do so unimportant. I think one very major factor contributing to happiness is when we have a goal to strive for. So what if death is the end all? What if this very short life amounts to non-existence?
There is another aspect of my particular belief that makes me someone who does not rely completely on science. There are elements of Vedic philosophy that are so real to me, so obvious based on my life experience, that are not and perhaps cannot (not sure) be explained by researchers. It proves to me that personal spiritual inquisition and investigation is important because it opens up and fulfills a part of my life that science does not and that atheism utterly lacks.
What a wonderful, well expressed, personal response! I understand because, like you, I need and now have a goal. Every religion has a goal. All the mainline "religions" and "secular religion" (such as "Communism") have goals. No ideology can succeed that does not. Their moral systems are merely the refined codifying of the means the people are to employ to achieve those goals. The Christian goals are achieving "heaven" for the individual and "the Second Coming" and then "God's Kingdom." Marxism touts a communal world. Hinduists seek Nirvana. The problem with our secular ideology is that "the pursuit of happiness" and "the American dream" are poor goals.
My goal in life is to convince people that these goals have become almost useless because we have, since they were dreamed up, learned much more about ourselves and the universe. The goal doctrines have become outdated and explain why Christianity, for example, has become so divided. In unity there is strength, in disunity there is. .
As I explain in "The Last Civilization," the adopting of an ideology with the goals of advancing the space program to where we could colonize space, to controlling over-population and the over-exploiting of our environment, encouraging multiracial marriage, and bringing about a moral code reform.
Incidentally, I have read 100 of the RigVeda verses and was disappointed. All that part of the veda was was an endless repeating of pleas to the gods to enable them to overpower their enemies so they can get more loot. To that end, the promised to make sacrifices for their gods and provide them with their favorite nector.:yes:
