The topic of this book is reality. Actually an impossible topic. Reality is about everything, hence it cannot be summarized in a book. Nevertheless, understanding reality is sufficient enough through understanding the most important notions of reality, such as consciousness, culture, dualism, ego, enlightenment, evolution, freedom, the I, illusion, language, life, love, pain, science, spirituality, suffering, welfare and wellbeing. For that reason, this book explains all these and more notions briefly but clearly. Besides understanding reality, this book offers tips for achieving personal, collective and universal wellbeing.
