Create a magnificent design for my spiritual hardcover book

Daniel F. Parmeggiani

I teach about the real requirements for permanent happiness and fulfillment.

I need a magnificent hard cover design for my upcoming spiritual, non-fiction book, The Magnificent Truths of Our Existence. The subtitle is "Beyond the chaos and confusion of our lives, there is a deeper reality that guarantees permanent happiness". It's a book about the spiritual realizations that not only saved my life, but showed me the way to permanent happiness and fulfillment. The book reveals our true nature, which is absolutely innocent and lovable.
I want this cover to really convey the message that this book contains the secrets for true happiness. Here are some ideas I was playing with:
In the darkness, a treasure chest is opened and a bright golden light shoots out. Maybe the bright light can be like a spotlight lighting up or creating the title of the book.

I also included my current facebook header as an attachment to give you an idea of other themes I was playing with.
Please do not feel constrained by these ideas. Sometimes the best one is the one yet to be considered.

Cover is 5X8. "About the author" on back page with author headshot (see attachments) Publisher logo either on the back or on the spine (see attachment). Leave space for bar code on the lower right of the back cover.

I want original artwork that makes the book stand out from the rest. I want an attractive, intriguing cover that makes people want to pick up the book and see what it's about. Also remember that this is a spiritual self-help book, not religious.
