Sujanks Ji, now you have collected a lot of information. As you mentioned there was no worshiping system before where as today's Hinduism is focused on Idole worshiping. It means ancient Hindu practice was differnt than modern day Hindu practices. Now find out why Hindus changed their pracices? Whether new practice is efficient or inefficient compare to the old one? Why did they change? Was the change an evolution or declination? This will clear out all those blind faith we have about our Hindu practices. As I have told you that you will find 330 million gods in Puranas, you found it. Now find why only 330 millions? Why not 320 or 340 millions? For that you have to go to Veda, and analyze wisely. As you have already mentioned that Puranas were written in AD, now to get the answer of why 330 million, you need to know that why were they be composed? Under what ground were they (Purana) be written? I don't think it will take life long time to read all Puranas and Upanisads. There are 108 upanishadas, most of them are like one chapter of a book. Few are lil long though. I have gone through some of these. I think Puranas are lil longer but not that long as you think. I have read some of these as well. All I can say is if you read them in your free time with interest, you can finish them all in 6 month. I know the gist of Puranas, however, I want someone who want to read them all. Because right now I don't have time to read them though I want to :). Unlike Veda and Upaniseda, they are not online as well. Thanks for other information though, but let me not touch Bhakti, Karma, and Gyana in this thread. I probably will get lost. Let me be limited to faith. I will write only about faith and related, nothing more. Faith is belief. I m focusing on a popular belief among the Hindu society, which is, there are 330 million gods. Now answer has to come either affermative or negative, but rational and logical. As we know the age of Adwait Vedanta, which is about a thousand years and origionated by Shankaracharya. It is no longer a mith but a reality for us. We have to be able to know about 330 million gods, at least with similar accuracy as that of Adwait Vedanta. We have to establish a exploring culture. We had that culture, we lost it. Now we must regain it back. It is the product of exploration where the western world is right now. So please share whatever you know about faith.
