Figure 7.16 Energy being added to the self-replicative system A in the form of newer intrinsic material (1, 2,
and 3) and external gradient (this external gradient is applied either to aid the interaction between the intrinsic
materials or to impart a particular dynamics to the system for favorable environment for the interaction).

Here because of the process of self-filtering, copies of intrinsic material 1, 2, and 3 are introduced.
The property of self-balancing comes into dominance and the systems try to adjust itself into the most
stable state. As defined earlier, the initial state is the most stable state; following is what
happens tozthe system A. Two subsystems within the main systems are made as shown in Figure
7.17. The alignment of subsystems A1 and A2 is similar to the one of the initial system, that is, A.
Please note that such system is possible, because we can control the external parameters, namely,

Subsystem A1

Subsystem A2

System A
Figure 7.17 Creation of stable subsystems within the original system A (which as a whole is marginally unstable
under the external gradients and two independently stable subsystems). This step is the most crucial in the process
of attaining a self-replicative super system. This demands a unique selection of such replicative intrinsic materials
in the initial place, namely, 1, 2, and 3.
