Theoretically speaking, all the members (series as well as families) in the 
dynamic system should be mentioned repeatedly i.e. a3 many times as the 
number of series or families respectively. But, for practical purposes, the 
system may, as mentioned above, be simplified by arranging only those series 
or families whose relations to the middle members are so far known to us, 
and by adding thereto a few short lines symbolizing or representing as many 
series or families, other than those laterally arranged and the middle member. 
To make what we present to our readers a3 a dynamic system as compre- 
hensible as possible, it may conveniently be formed of four parts, namely :— 
the participation theory upon which the system is grounded, the system itself, 
the explanation of the latter, and finally the index to the members of the 
system. Now, on the side of the reader, in order to understand thoroughly 
the dynamic system thus presented, they should, first of all, master the 
participation theory, then proceed to study the system itself, then look at the 
explanation of the latter, and finally go to the index, especially when they 
have something in mind, the natural position of which they wish to find in 
the system. These four parts are, however, in final analysis resolvable to 
oneness, — each being in itself the theory, each in itself the system, and so 
on. I have described the participation theory above; so I shall now give 
the system and then the explanation and the index, in the following pages.
