I recommend reading these books and some of them I use in my trainings:

. The Chaos Point: The World at the Crossroads by Ervin Laszlo (ISBN-13: 978-1571744852) For the next six to seven years - roughly until the end of 2012 - we have the opportunity to head off trends that would lead to a critical tipping point. Beyond this 'chaos point', we either evolve to a safer, more sustainable world, or the social, economic, and ecological systems that frame our life become overstressed and break down. The Dutch television organisation IKON interviewed ERVIN LASZLO
. The Field: The Quest for the Secret Force of the Universe by Lynne McTaggart (ISBN-13: 978-0060931179) McTaggart, an investigative journalist , describes scientific discoveries that she believes point to a unifying concept of the universe, one that reconciles mind with matter, classic Newtonian science with quantum physics and, most importantly, science with religion.
. Slow Food (The Case For Taste) by Carlos Petrini (ISBN-13: 978-0231128445) For anyone who doesn't know, Slow Food is the antithesis of 'fast food', as it is represented by drive through burger restaurants, coffee in a to-go cup, and ready-to-eat microwave dinners.
. Your Body's Many Cries For Water by F. Batmanghelidj M.D (ISBN 0962994235) Recognizing the body’s signals for water is a lost instinct. Many illnesses are curable by hydration alone. All the reader needs to put Dr. Batmanghelidj’s theories to the test is to drink daily at least 2,5 litres of water from the kitchen faucet. See also the Watercure website.
. Emergence: The Shift from Ego to Essence by Barbara Marx Hubbard (ISBN 1571742042) Barbara Marx Hubbard describes the birth of a new being that she calls the Universal Human: "one who is connected through the heart to the whole of life, attuned to the deeper intelligence of nature, and called forth irresistibly by spirit to creatively express his or her gifts in the evolution of self and the world."
. Lost Secrets of the Sacred Ark by Laurence Gardner (ISBN 0007142951) Recent findings about the exotic properties of monatomic gold (white powder gold) and the platinum group metals are rediscoveries of an advanced science understood or at least known by the ancient Mesopotamian, Egyptian and Israelite priests.
. Tomorrow's God: Our Greatest Spiritual Challenge by Neale Donald Walsch (ISBN 0743456955) “This 'new' notion of God violates virtually everything you have been told by your society and taught by your religions about God.
