Two opposites and their attraction to one another

Mimosa pudica (from Latin: pudica "shy, bashful or shrinking"; also called Sensitive Plant), is a creeping annual or perennial herb often grown for its curiosity value: the compound leaves fold inward and droop when touched or shaken, re-opening minutes later.

Could it be that all living creatures present themselves in either one of two formats or facets? Or, elaborating a little more - they are constantly oscillating between the two following discrete - and opposite - states: interior and exterior, inside and outside?

Upon touching the inside, it retracts. Upon retracting, it reaches a point where it needs to expand, so not to disappear, so it can be felt, so it can exist. On the other hand, upon expansion, it reveals its inner compartments, chambers - all unguarded, visibly vulnerable. The more it expands, the more fragile it grows. To fully enjoy its existence comes at the expense of risk and danger.

In between these 2, somewhere in time it reaches what is called equilibrium, or balance. Some say balance is not a single point in time, rather, the whole process that can be summed up as change.
And that's all that there is to it. From day to night, night to day, it morphs from one form to the other, waving to balance on the way.

All right, to make my point, forget the picture - let us talk about me.
