The Threads That Lead to Divine: (Google narrated)

This audiobook is narrated by a digital voice.

In this excellent exposition of ancient Indian thought systems, the authors rig up an interesting debate among proponents of these systems, finally leading to the conclusions well established by Vedas and Upanishads.

The book is based on the well-known work namely The Brahma Sutra of Sage Badarayana.

A good book to get a quick introduction to Samkhya, Vaisheshika, Yoga, Teravada, Vijnyana Vada, Shoonya Vada, and Anekantavada and their contrast with the Upanishadic views.
