I think that we carefully have to investigate what actually enables complex structures.
I have found that Complexity is derived from the linkage of opposites such that they do not contradict each other during linkage.
As I get it, self awareness development is essential to non-destructive linkage between opposites, and by practicing TM for example, we actually reinforce this linkage, which in turn enables finer manifestations of complex forms.
In my opinion, the nervous system of self-aware complex systems, is more software than hardware, such that their abilities to develop internal and external complex forms is increased by non-linear frequency.
Non-linear complexity development, as I get it, is actually the non-linear development of the balance between opposites, which is exactly the manifestation of the linkage (the unified-field, which is the natural source of opposites) among opposites.
Reduction is only the local aspect of complex systems, and can't really capture complexity's development similarly as (by analogy) a one eye viewer can't get 3D vision.
Non-linearity and Chaos Theory plays a main role in our understanding of Complexity's development as a result of a developed balance between opposites like order and disorder.
Here are two papers about this interesting subject:
Is the normal heartbeat chaotic or homeostatic?

Some outstanding paper from the class of Spring '03 of Oregon University:
Human Beings as Chaotic Systems:

As I get it, Self similarity upon different scale levels is exactly the optimal condition to develop deeper awareness of finer mental activity, where the non-local property of this self-similarity over scales is the property that actually enables us to transcend and directly be aware of the source of all possible manifested phenomena, which are naturally free of contradiction, otherwise they do not exist as complex forms.
I believe that we can learn much form our biological complexity, for example, our heart:
Each cell of our heart has the ability work (to produce a beat) independently of the other cells. Yet this independent (local) ability is synchronized by special cells that (by using a non-local principle with respect to the independent cells) coordinate their independent abilities into a one coherent heartbeat, which actually enables our existence as living complex systems.
Furthermore, by Chaos Theory we have learned that this Non-local\Local linkage is characterized by self-similarity over different scale levels of each heartbeat, which actually demonstrates the beauty that is found at the basis of the non-linear dynamics of our heart.
It enables simple principles to manifest great complexity by avoiding contradiction between the independent ability of each heart cell to work in its own beat (if the linkage between Non-locality and Locality is interrupted, we get independent beats which contradict each others, our heart stops and we die).
So our heart is a concrete example of Mutual Independency (synchronization (non-locality) among independent beats (locality)).
In general any autonomy that is based on dichotomy between opposites, can't be used as a fruitful base ground for Complexity's development, because by this dichotomy the opposites are not opened to each other, and without this openness there is no Complexity. Actually the whole idea of Complexity is derived from the ability of opposites to be developed beyond their isolated ids without losing their ids during interaction (Mutual Independency).
In my opinion, Complexity is the exact manifestation of linked ids, where linked ids is actually the fundamental term of any axiomatic system, such that each axiom saves its id (it is not derived from any other axiom) during linkage (the unified field) and each axiom does not contradict any other axiom (again, because all ids are derived from the same source, known as the unified field).
Mutual Independency is the main principle, where the mutual and the independent are oneped to each other.
