'The Boundary of Belief' is about the author's struggle to come to terms with the Reason for his mental breakdown with manic-depressive psychosis. The book is the first in a series of five books, called, 'Reason to be Whole'. It is about the Flaw in Man's System of Belief in human judgement, which is represented, collectively, as the System of Democracy. Book 1 introduces the way in which the series explains the actual Reason for the Existence of the System and Process of Belief and why belief in the freedom of will and choice of the self is Relative and not the Absolute Fact of the Single Truth but how the Truth of Nature ... the Nature of Truth nurtures the nature of Relative understanding into human consciousness in the Process of Relative Movement in the Universe, the Process of Evolution of Understanding Relativeness. 'Reason to be Whole', R2bW, is about the Actual, Single Truth, Fate's Cause, the Cause for Existence of Life and Death in the Universe and the Reason for the Evolution of suffering Relative ignorance and its consequences in the reality of the real World.R2bW is All about the Perfect Paradox, which is the Absolute Truth of Reason for the Order of the Universe and the Existence of the Universe, itself, the One Self, and the Evolution of Disease of the Body, Disorder of the Mind and the Healing and Cure of their cause, the reality of belief in Malignancy and Toxicity and their consequences: degenerative diseases, cancer and death. It is about the Reason for the belief in the material nature of matter and why the System of Capitalism is failing the People of the real World. It is about the Cure for insanity and evil. It is about what the Higgs boson is made of in the Reality of Actualness and why the Big Bang did not happen. R2bW is an explanation for the Complete Understanding of Dimensionlessness and the Reconciliation of Absoluteness and Relativeness, the Reconciliation of Einstein's Theory of Relativity and Quantum Theory. It is about Understanding the Reason and Cause for Sanity, the Logic of Truth. The series of five books is a Theory of Everything and is about the Whole Person and concerns the Consciousness and Awareness of Energy, what the Universe is, the System of Complete Understanding of the Continuum, Cause and Reason for Everything, Being ... One, who is God. It is All about the Meaning of the Word, God, and the Truth of the Will of God and the Way Consciousness and Awareness work as the Process of Evolution of Understanding, the Process of Relative Movement, the System of Being ... Energy. Books 2 and 3, 'what's it All about ... what it's All about' and 'Reason for Everything', will be published later in 2014. Book 4, 'a Way of Understanding', aWoU, is about the Only Way in which the System and Process of the Nature of Truth can be understood which is by Understanding the Logic of the Cause for the Existence of Life Beyond Relational Depth which can only be achieved by participating in, experiencing and understanding the Process of Person-Centred Counselling with Tenderness to the Absolute and Beyond. It explains why no one will believe R2bW until they reach the Point of Realisation of the Point of Understanding. It will be published later along with book 5, 'the Will to be Free'.
