What do you want the most in life? Is it immediate gratification, or continuous prosperity and development? Is it the best for you and your family, or the best for the entire world? Or is it simply to feel the best, as much as possible? Because your needs determine your life, as they always seek to control you, in every manner. While you can still choose their entire fulfillment, in any order, manner, and priority you desire. Because everything common, necessary, unique, delightful, and original in life and in the world, you do in order to fulfill your needs.

While this is exactly your hierarchy or harmony of needs and fulfillment, while if you remain ignorant of these, you end up living your life randomly, ideologically, or instinctually, but not at the genuine intelligent human level.

Your needs might not always regard you, as you expect. Study yourself throughout your fulfillment, to see how you do not actually live your life on your behalf, but 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 always eat in order to feed your cells. It is the same with thirst, security, breathing, recovery, and reproduction, because you fulfill all these in order to tend to your cells, and to keep their genetic material in the world long after you are gone.

Yet there is still more to your needs and fulfillment to study and understand, because you live your life on behalf of your cells, body, and subconscious mind through the fulfillment of 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.

But can you ever make order in all these? Study yourself now, to find your lifelong activity filled up 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 needs fulfilled randomly or in a precise order or hierarchy.

Throughout this book, we model the human needs and fulfillment while identifying and classifying them accurately, by studying closely all hierarchies and harmonies of needs, helping you distinguish the necessary in your fulfillment from the irrelevant, in order to find a clear meaning in life and in the world, for you and for the entire world.
