You are right that links to better translations are what I should link to. However, even here, you should be mindful that translations of Dharmic scriptures are tied to Philosophical schools of thought (or Schools of Vedanta). So if you are asking me to give you a link I would have to give you links to Tattvavada (which is the school of Vedanta I follow). However, there are translations provided by Advaita and Vishishtadvaita (and other sub-schools) that differ slightly in their interpretations and I'll be doing disservice to them by not linking their work too. So eventually you will end up with having to learn under a learned Guru anyways. And you won't find Gurus who are well versed in their concepts in the Western academia at the very least. You will have to travel to India and explore the various Mathas (study centers) and figure out which Philosophy appeals to you. This is purely because Sanatan Dharma is not Dogmatic like Western Religions. Here you have the choice to choose your path. You have Monism in the form of Shankara's Advaita, Qualified Monism of Ramanuja's Vishshitadvaita to Dualism of Madhva's Tattvavada. All 3 schools (these are primary schools with many sub-schools with subtle differences from the main school they branch out from) differ in their interpretations significantly when it comes to answering few broad philosophical questions:

1. Who am I? Do I really exist or am I an illusion?

2. What is this Creation? Is this real or an illusion?

3. What is Time?

4. Is there a Creator? Or is there none?

5. If there is a Creator then what is the relationship between me and the Creator?

6. Are we many individual Aatmas with each having separate, distinct reality or one Aatma living in an illusion that it is separate, distinct reality?

All these Philosophical questions derive from the Vedic scriptures viz: Vedas, Upanishads, Brahma Sutras, Bhagavad Gita, Mahabharata, Ramayana and the Puranas. The Philosophical Schools (or schools of Vedanta) have spent thousands of years researching on these fundamental Philosophical questions. To point a link to an authentic translation is hence a very difficult task: for one, there are very few and far between. Two: it is a mammoth undertaking to translate the entire corpus of literature that has accumulated in Sanskrit over the past thousands of years. Three: most of the English translations from Indian Indologists exist only for one school: Advaita. Other schools haven't been translated yet (though for Tattvavada there is translation now available in the form of 37 Sarvamoola Granthas of Madhvacharya — the founder of the Tattvavada school of Vedanta).

The problem also is that Sanskrit has a lot of "non-translatable" words. There is no such "authentic" translation as when you "translate" you will have to find meanings that fit the language you are translating into which eventually leads to dumbing down the translation as the vocabulary is not sufficient to describe the Sanskrit word.

For example, most Western Indologists wrongly translate Aatma as "Soul". However, what is Soul exactly? It has Religious connotations attributed and inline with Abrahamic interpretations of what a Soul is which is not what Aatma is in Sanatan Dharma.

What is Dharma in English? Most Western Indologists incorrectly translate it as "Religion" (or some use the slightly better term "Righteousness"). But Dharma is not Religion at all. It is "Eternal Truth" (hence is called Sanatan Dharma) that is based on concepts of "Righteousness" and "Duties" tightly interwoven into the "Karmic cycle". It is not Dogmatic in any way, shape or form. There are no "Commandments".

What is Karma in English? "Every action has an equal and opposite reaction"? Nope. That is just rudimentary translation of what Karma is. Because in this translation, there is an expectation that the Karmic result would happen immediately or within a short period of time. However, in Sanatan Dharma, Karma spans not just one lifetime but infinite lifetimes. The Karmic cycle of the Aatma started from the very beginnings of Creation (through the breaking of the Hiranyagarbha roughly translated as "Golden womb" or Big Bang in modern parlance). So when Sanatan Dharma talks of Karma it talks in terms of Cosmic timescale which runs in trillions of years. The Age of Brahma (who is the one who ushers in the Creation on the command of God – Lord Vishnu), according to Sanatan Dharma, is 311 trillion years (this is the lifetime of birth and death of Creation itself, before it restarts all over again (Big Crunch followed by Big Bang), with Lokas (Multiverses) within it). The Karmic cycle starts at the very beginning of Creation itself and ends with the end of Creation to restart again in a cyclical manner. So how do I fit all this in a 1:1 mapping between Karma and an English equivalent? There is no such word in English which defines Karma in its entirety.

How do you translate Prāṇa in English? "Life force" or "Vital principle". Both don't sufficiently describe Prāṇa as Prāṇa is closely tied to Vāyu (also called Mukhya Prāṇa or the controller of the life force). Without explaining Vāyu you cannot explain Prāṇa as Vāyu is the controller and the cause.
