Nesting, nested: Things within things within things - the principle of the russian doll, where a whole chain of similar items is each enclosed by the next bigger item, all of which finally fit into the biggest of them.
One example of nested items we find in nature, where atoms form molecules, which form biochemical structures, which form cells, which form organs, which form bodies, which form families, which form cultures, which form species, which form biospheres or ecologies or planets, which form solar systems, which form galaxies, which form universes...
On the spiritual level, individuals form groups, which form larger groups - the group formation can be nested at any imaginable depth -, which could be thought to finally form a whole, the supreme being.
From the individual down, another chain of nesting can be observed: the fragments or fibres of the personality, also called identities (the various "roles" a person is playing in life), and sometimes additional splinters of consciousness ("entities") which are more or less aware, and are perceived as independent and different from the main personality.
