> Do you have any easy book recommendations to learn this kind of insights - grammar and the way of living.

Goldman’s Devavanipravešika [0] was what I learned Sanskrit from, that will teach you the grammar but Sanskrit grammar is notoriously difficult to learn, it functions almost like a computer language (though, not quite), it was the first formalized language, formalized into a system of thousands of rules that young kids of the upper castes would spend years memorizing. This book is a much simpler way to learn the grammar, but it still won’t be easy.

>Do you have any Bagavad Gita book recommendations that goes into the kernel of the teaching without all that noise?

Any interpretation you read will have some measure of sectarian influence, even my interpretation is quite contemporary, I’m drawing from more recent currents of thought to discuss the Gita in terms of an economy of force—-a good stepping stone between the text itself and this contemporary thought would be this volume of essays, in particular “The God and the Warrior,” by Mario Tronti, which touches on these things directly [1]. In the end it will be up to you, after your own studies, to form your own interpretation and your own relationship to the work.
