This book is the first of a series that considers the many aspects of reality. I call it ‘It all starts from within’ because reality starts with each of us individually and independently. It starts from our inner self before evolving into what I would call the collective reality, meaning a generally agreed upon state in which groups of people, entire nations, or the whole world believe. That reality includes beliefs, cultures, ideologies, etc. As we change and adapt to our environment, our reality changes as well. New realities emerge… Chapter one is about perception and our senses. It demonstrates how perception is impossible without our senses. Whatever angle of reality that’s being analyzed, one or more of our senses plays a momentous role in its understanding… Chapter two considers the role of the brain in the making of reality. It delves into how the brain can make the mind behave a certain way under certain circumstances… Chapter three looks at the mind, which I call the ultimate maker of reality. This chapter describes the mind as that intangible component of the brain and where reality or all realities stem from after, of course, being picked up by the senses and the brain… Chapter four attempts to define reality itself after it’s perceived by our senses, analyzed by our brain, and processed by our mind…I consider five questions in my attempt to answer the question: what is reality? They are: what are things and why do they look different from one another? What is life and its origins? What is death? What is superstition? What is space and are we alone in the universe?
