Relatedly, also – Since OP asked this question on an occultism blog rather than a Judaism one, I'm going to go out on a limb and assume they're not Jewish. And I think that if you're coming from a non-Jewish background, the biggest barrier to understanding the Torah is that Jews do not engage with our texts in remotely the same way that Christians engage with their texts.
Don't start by treating the Torah like a literal narrative account. For many people, this is the only way they know how to engage with Biblical texts, but in Judaism, it's really not the main way we read the Torah at all.
Torah is a collection of stories and laws and poetry – the fact that we Jews believe that it is divine in no way means that we believe that it is all literal; this is much like how the fact that English lit scholars tend to believe that Poe was a great writer doesn't at all mean that they think he literally slept in a tomb by the sea.
When approaching Torah, there are four main methods of interpretation:
First, there's p'shat or "surface meaning": This is the closest thing we have to literalism, but even p'shat is not exactly biblical literalism in the way that Christians tend to mean. Think of this as "that type of literary analysis you did in high school" and you won't be too far off. A p'shat interpretation of Edgar Allen Poe's "Annabel Lee" would be something like "the narrator loved this women so much that angels killed her, and now he lies down in her tomb – the rhyme scheme, repetition, and meter conveys the narrator's intense mournfulness."
Second, there's remez or "hinted meaning": This is something more like a higher-level literary critique, involving more hidden or symbolic meanings within the text. A remez interpretation of Edgar Allen Poe's "Annabel Lee" would be something more like "when you contrast Annabel Lee with poems such as The Raven, Ulalume, and To One in Paradise, you see an evolving view of the concepts of death and doomed love."
Third, there's derash or "inquiry": This is a more active engagement with the text, where scholars draw meaning and stories out of what's written by contrasting multiple texts, and then additionally reading between the lines of what's written. A derash interpretation of "Annabel Lee" might be in the form of an imagined dialogue, in which Annabel Lee's ghost responds to the narrator's assertions in the original poem by quoting passages from Edgar Allen Poe's other works – and this dialogue could end up suggesting a meaning in which the young love referred to in the poem was symbolic of something else entirely.
Finally, there's sod or "secret meaning": This is an esoteric form of interpretation which I'd steer clear of entirely until you have a fairly complete understanding of the contents of the text and their more simple interpretations. A sod interpretation of "Annabel Lee" might look like someone pointing out that Edgar Allen Poe tends to use the letter "L" for all of his doomed female love interest characters, then going into a thesis-length analysis of the symbolic meanings of the letter "L" throughout all of English literature, and then arguing that a connection they've discovered between "Annabel Lee" and Shakespeare's "Measure for Measure" through analyzing the nature of the letter "L" elucidates a deeper human meaning of the nature of love and tragedy.
Tl;dr: If you're having trouble getting what we Jews are getting out of the Torah by just reading it plain, that's probably because that's not really how we read Torah. When we say that every letter is sacred and full of meaning to us, we're not just speaking metaphorically.
