Mindessence contains ideas and methods to deepen our understanding of life and death and bring us to a realisation of our true nature. To the author, the idea that some of us are somehow 'sane' and some 'insane, ' is false, he believes we are all absolutely sane - it is just a matter of degree. What Society calls 'mental illness' Tony Caves calls Perplexity. Transparency is the name he gives to a state of freedom from Perplexity. Transparency gives us space in which to experience Mindessence which is a state of dynamic ease and relaxed alertness beyond ordinary notions of sanity. The book explores the ways in which we are conditioned by society, through our upbringing and education, to live and die in a dream world of our own making. It then explores methods for de-conditioning ourselves through simple techniques, such as the use of static and moving Meditation, to help us become aware of our vast and timeless Heartmind and to plant the seeds of Transparency which then flower into Mindessence.
