We could probably do a great bit of squabbling over what the "sanctity of human life" means, but in terms of preserving every human life, I'd disagree that the Rig Veda espouses this explicitly (at least from what I've seen). It's approached metaphysically, but not delineated in any concrete religious laws.
The Rig Veda represents what is known as Sanatana Dharma (the pure and original form of what is today known as Hinduism). "Hinduism" as practiced and defined today is a corruption of Sanatana Dharma and is not the same thing.
In fact, Sanatana Dharma is not actually a religion as other formal creeds with lists of laws such as Christianity, Islam, Judaism, and other "typical" religions are. Sanatana Dharma gives reverence to individual spiritual experience over any formal religious doctrine. Wherever the Universal Truth is manifest, there is Sanatana Dharma — whether it is in a field of religion, art or science, or in the life of a person or community. Wherever the Universal Truth is not recognized, or is scaled down and limited to a particular group, book or person, even if done so in the name of God, there Sanatana Dharma ceases to function, whatever the activity is called.
Sanatana Dharma r
recognizes only one Supreme/"God" (a better term would be Truth) . It is thoroughly scientific religion and science meets hand in hand. Here theology is based on upon science and philosophy.
"The Vedic revelationis of all revelations the only one whose Ideas are in perfect harmony with Modern Science, as it proclaims the slow and gradual formation of the world."
You raise some great objections and I agree that these are the central problems of religion. The question of "which religion?" is a deeply personal one that has a lot of inputs, and I'm in no position to judge others based on my own conclusions.
But I'd offer that at its core, all religion is about the individual and his/her pursuit of truth. In my mind, someone who is honestly searching for truth is in a way religious. That's one of the reasons I'm so fond of Christopher Hitchens, despite how strongly I disagree with him. He strived for the truth and was consistent in thought like no other atheist I have heard.
OK -- now do you think that the true God, whoever/whatever God is, would punish people for not arriving at the actual truth, assuming that they have used their faculties, as you described, to seek out the best version of the truth they can? Many religions, Christianity included, seem to suggest that it doesn't matter how hard you try, if you pick the wrong God, you're in trouble. (First Commandment) This seems a bit unfair given how hard it is to answer the question of "what religion?" What do you think? I personally think that God would be more concerned with how you have lived your life - morally, ethically, etc.
What you both describe here is at the core of Sanatana Dharma. All that matters is Truth, and that Truth (what can also be translated as God - Sanskrit is very hard to translate into English) pervades everything. "[FONT=Verdana, Arial, Helvetica, sans-serif]
Truth behind all ephemeral truths. The Vedic concept of God/Truth is an architect whose structures all exist within him. Nothing can exist outside the Supreme Reality".
It doesn't even matter what you call yourself. A self-proclaimed Muslim, Christian, even atheist can all follow the path of Sanatana Dharma (he/she will probably be doing it unknowingly, though).
.It is also important to note that the Vedic concept of God is not like God as generally known to people. God in Sanatana Dharma is not the personal God like that of the Abrahamic religions. I don't even know how to describe it -
its nondualism is really beyond monotheism - which creates a fundamental duality of God and man. Evil is not envisaged as a quality opposed to good. It is the absence of good, just as darkness is the absence of light, not its opposite quality. This is just as Truth has no opposite quality, just the absence of truth.
It is very difficult to explain all of this, though, since the Vedas and other Shruti are written in Sanskrit, meaning it's extremely difficult to properly translate the meaning into English. I am the first generation in my family to not know Sanskrit but at least my grandma has been teaching and explaining these to me for as long as I can remember time using a combination of English and Hindi.
Also, the Bhagavad Gita is not on the same category as the Vedas. The Vedas are what are known as Shruti, meaning it is what was revealed from the "divine breath" itself. The Bhagavad Gita is Smriti, meaning it is more of a remembered story portraying dharma. Basically, the Shruti is supreme in Dharma.
Edit: The caste system is BS lol. One of the many corruptions (like vegetarianism)
