"This book is devoted to the kA, one of the most significant categories
applied by ancient Egyptians to describe the world and man in the
world. Although the kA problem is of great importance for Egyptology,
from the very beginning I did not intend to address my work solely to
Egyptologists, but also to the historians of antiquity, archaeologists and
anthropologists in general ... It should be noted that the problem of the
kA is very complicated and requires analysis of different kinds of
monuments in various aspects. Therefore most conclusions made in
each separate chapter are not definitive and are complemented and
defined more exactly in the subsequent chapters. Thus, the author's
attitude becomes clear only upon reading the book entirely, the last
pages included."
