Maybe try "Buddhism without Beliefs: A Contemporary Guide to Awakening" by Stephen Batchelor
Or even "Waking Up" by Sam Harris..
I will point out that every piece of information is filtered through some form of translation, we add to it and take away from it, we match it to our world view or dismiss it in the same way. Even our own emotional, intellectual and motivational attachment to pointing out others misunderstandings is another form of translation, perhaps its governed by an idea that information and technique is somehow Purest at its Source (maybe we can add to our well being when this idea is challenged)
In my opinion it is a "trick of the trade" in spiritualism to drag observational information we don't or even can't understand into the Obscure world of mysticism. We end up saying well it just can't be fully understood using everyday language, leaving us in the delusional space that things that can't be understood must be evidence of the supernatural or transcendent realms. When we turn a curious skeptical observation back onto the conclusions we have about our existence, maybe we can see we really are just taking comfort from our ignorance.
