We live in an objective world, with almost everything happening everywhere causally, naturally, and fairly. Your entire lifetime activity is also causal, since almost everything happening in your life is a continuous succession of causes and effects. This means that, through a highly systematic study, you could be capable to place all events of your life along one single line of causality. And since you are a living human being, this is your own lifeline of causality. When you study your lifeline of causality closely, you may understand the reason why you have chosen and done everything throughout life in this specific manner, in this specific order, and for these specific reasons. Even more, through your own lifeline of causality, you may seek to understand your own meaning in life, your own meaning in society, and your own meaning in this world, because these also have their own lifelines of causality. And by studying these, you are capable to pinpoint the exact interaction between your own lifeline of causality and these extraordinary, comprehensive lifelines of causality, in order to identify, study, and explain all significant events of your life and of this world, how they happen, for what reason, and through what circumstances. This book studies your life and all significant events influencing your life, how everything happens, and through what circumstances, because everything is always found along specific lines of causality, since everything is connected. You will understand human beings, society, and this world, along with al higher beings of the wider world.
