I have gone through following phases, as far as my "beliefs" are concerned.
In chronological order:
Hinduism, because of Gods and Goddesses from Hindu Mythology! I was taught Ramaraksha, Ganapati Stotra and many other shlokas. Like everyone else, I honestly believed in Mahabharata, Ramayana, Puranas, whatever I was told at that age.
2: Theist:No "ism" here!!!
I came to know about other religions and learnt that all the Gods are basically the same! Btw, remotely relevant is an excerpt from "An Autobiography" by Pt. Jawaharlal Nehru
Logic and scientific studies demand proofs and logical derivations. But how can you prove existence of God? And even if divine power was to exist, if its beyond scope of our control, whats the point in following rituals? राग यायचा विशेषतः "पाप करे और गंगा नहाए" टाइप लोकांचा, धर्मवारून भांडणार्यांचा आणि बुवा लोकांचा.... हा असा राग तर अजूनही येतो!
Personal experiences/ experiments/ reading/ discussions regarding Hinduism/sacred texts made me realize that I was being a blind atheist. I also learnt that atheism does have a place in Hinduism and also that most of the rituals do make sense!
If logical reasoning/ experiences stand for most of their(believer's) claims, I cannot possibly refute their remaining claims that I do not truly agree on as of today! There are possibilities: I might not have reached the required level of maturity, my senses might not be developed to an extent where I can grasp essence of their science(?). Better way: सरळ सांगणं "मला माहीत नाही!" :)
6. What Next???
The most appealing is the Hindu philosophy.
But the question remains unanswered... What is Next???
That..... even I do not know! Don't worry, I will keep you updated!!! :)
