Human beings seem to have been always aware of something they called consciousness and have not stopped wondering what it is, what it does, where it came from, and why we have it. This book is testimony to the continuous attempts to crack the riddle, in the 21st century no less, if not even more than before. The book expresses two major convictions. One is that consciousness has a multiplicity of aspects, which need to be considered in order to deepen understanding of this phenomenon and of ourselves. These include in the very least biology, philosophy, religion, mathematics, physics, physiology, and psychology. The other is that the next phase of human evolution may well be the evolution of consciousness - its expansion, development, and enhanced ability on our part to recognise and control it, shape it and put it to our use for improving our chances of survival and enhancing our happiness. This book is aimed at contributing towards the attainment of this goal.
