This book is a result of my childhood questions about myself as I wondered how did I appear to be myself suddenly with hardly any past recollection and I wondered about my understanding of my own experiences in my life and things of that nature. I wanted to look beyond the 'Creator's wish' part, a prevalent mode of resignation of the thought process, to find a logical and scientific explanation by myself through reading. Eventually I developed the wisdom that the answer lies in the understanding of the brain. When I realized that it is my brain that is somehow generating all my experiences for me, it led to a pretty engrossing experience trying to understand it since. Since this is a book about the brain, I thought it was necessary to discuss the fundamental aspect of its structure. However, I only laid a gross picture with broad strokes only after briefly discussing the highlights of the history of evolution of the brain. Then I tried to address some of the big questions like the consciousness and the generation of the mind and self from a neurological point of view. I went ahead and discussed the mechanism of some of the attributes of self as well. Some of the functional aspects are elucidated as how we fall in love or how we navigate directions and so forth. Computation is the basis by which the brain derives its conclusions. The plasticity of the brain enables us to learn new skills. The genetic aspect cannot be overemphasized. I have included some fascinating data that has recently been found out in these regards. Psychiatric illnesses always fascinated me. I have discussed the genetic basis and pathophysiology of a few of them, like Depression, Alzheimer's disease, etc. The whole book is written on the basis of the latest findings by dedicated professionals. Here I am like a collector who has put all this in a concise deliberation to share my own understandings regarding what it takes for each of us to be the way we are.
