This book isn't neuroscience - in fact, you'd be hard pressed to find scientific roots for many of the ideas elucidated upon in this book. But as you delve deeper into this book, what you will come to realise (as aptly put by Arjun) is that it is only so far that logic can take you on the stairway to (a metaphorical) heaven.
By borrowing as much from tantra as contemporary neuroscience, by diving as much into the Vedas as quintessential anthropology, and by weaving his narrative from fields and branches hitherto unwoven, Arjun brings to life his perspective on what it takes to live a fulfilling, pleasurable life.
