I made a mistake when I tackled the Bible years back: I read it in Victorian English, without any expert commentary, so I understood shit about fuck. Maybe less.
This time, when I decided to read the Gita, I chose a copy with modern commentary from sw. Narasingha and it was dumbed down just enough for me to get some of it.
Full disclosure, I subscribe to no religion - frying your brain on Ayahuasca/DMT will do that to a lad - but, like many, over the years I did develop my own personal set of spiritual beliefs and I have to say that so far it seems that I share most of them with Hinduism: aside from the practice of worshipping any kind of named and specific deity, or an assortment of such.
Karma? Yes. Reincarnation? Yes. Eternal soul? Yes. Samsara? Yes. Everything and everyone being part of one, a.k.a. oneness of consciousness? Yeppers.
