Question: I'm looking for a book that isn't too dense and that is usually recommended for someone who wants to learn of the mind/consciousness but doesn't know where to start.

Answer: 
To be honest, it is hard to recommend a single book. If you really want to understand philosophy, you must read many books. So you might want to start with Hume's **Enquiry Concerning Human Understanding**, Berkeley's **Treatise Concerning the Principles of Human Knowledge**, Descartes' **Meditations** and **Discourse on the Method**, as well as Kant's **Critique of Pure Reason** and **Principles of the Metaphysics of Morals**. These are by far the best epistemology/metaphysics books I have ever read. It might seem obvious recommending such well-known books, but they are well-known because they are truly phenomenal. Also, if you are interested in the development of mathematics, and in particular analysis, I would recommend **The Analyst** by Berkeley -- a remarkable book. If however, you do not have time to read them all, start with Hume's **Enquiry Concerning Human Understanding** and Berkeley's **Treatise Concerning the Principles of Human Knowledge**, and avoid Kant' **Principles of the Metaphysics of Morals**, and any of Kant's books because they are very difficult to read. You need to read each book at least twice to understand Kant.
I have been studying (in my on spiritual quest) the topic of consciousness for more than a decade and I find that most of the stuff on consciousness severely lacking for two reasons. 1) it is too scientific and 2) it is too New Agey. I stumbled across a book last year that was a free download by an unknown author and the book just blew me away. The book is called "Demystifying the Mystical" by Endall Beall.

A few months back I saw that this author has created a series called the Evolution of Consciousness and I immediately purchased the books through Amazon. The first book is good and it takes on Philosophy and brings a new light to the field. The second book is called Willful Evolution and it makes so much sense and is more practical, not scientific or New Agey. Actually and the Demystifying the Mystical book (which demystifies what most people think of as mystical) so it kind of tears the New Age apart (with good reason). There are more books to the series that I am looking forward to reading.
