Twinship and Consciousness

Do you think you are born a one-off, a unique individual entirely different from all others? Do you feel apart from others, or part of them, that you belong to yourself - responsible for yourself alone, or that you belong with and for others?
For the author, who, as an identical twin, was factually one and the same as her twin before the egg split, these questions as to what constitutes the self and how it emerges from the cosmos have been particularly pressing. In separate cots, they cried every night for three years till put into the same bed. It was like a marriage from birth. In this one life on Earth, should these twins ever have been parted? Does science offer any clues as to what underlies the superficial appearance of separate consciousness, of separate people?
This book is both a description of the transformative experience the author went through and a serious quest for understanding, enquiring into psychotherapy, philosophy and quantum physics. As this dilemma of separateness and relatedness is the human predicament intensified in twins, this story is about all of us.
