What do you need the most in life? Is it knowledge and continuous development? Is it to have the best for you and your loved ones or the best for the entire world? Is it to watch TV? Your needs determine your life consistently, while they control everything that you think and do. Because everything common, necessary, unique, delightful, or original in life you do in order to fulfill your needs.
Yet your needs might not regard you always, as you expect. Study your life through your needs now, to realize that you do not live your life on your own behalf, but you live it on behalf of your cells. Because your entire activity is meant to tend to your cells in every manner, and nothing else. Your eating activity is an example, since you eat in order to feed your cells, always. It is the same with thirst, security, breathing, recovery, and reproduction: you fulfill these in order to tend to your cells, and even to keep their genetic material in the world long after you die.
Yet there is still more to your needs and life to study and understand. You live your life on behalf of your cells, body, and subconscious mind, through your lower-level needs. While you live your life on behalf of your family, community, nation, society, and the entire world, through the fulfillment of your needs of higher levels and higher classes. Because people expect you to fulfill some of their needs too, while they also fulfill yours. Study yourself now, to find your lifelong activity filled with a multitude of needs, all being more or less important, harder or easier to fulfill, higher or lower in nature, addressing higher classes of life or only yourself, with all being fulfilled many times simultaneously.
Throughout this book, we seek to understand the human needs, to make order in this entirety, to classify and model them accurately, and to find all hierarchies and harmonies of needs, in order to help you understand the good from the bad among everything that you do in life, in order to be able to distinguish the necessary from the casual and the irrelevant, and in order to find a clear meaning in life and in the world, for you and for everybody else.
