I think the 3 characteristics of 'our world' is aniccata, dukkhata and anattata.
I understand the world is 'dhamma' (as in "normal process" or dhammata - thai reads it as tammada ;-). [The Buddha says -- in the titpitaka -- this applies to all 'compound things' (not 'elementary things' like atom, photon, quark, etc ?) and if we are 'attached' to these compound things which will always change in its course (of life) we are bound to get attached to dukkha. This dhamma (attachment) applies to 'everyone' without a choice and 'no-one' in particular -- anatta.
We should strive for 'loving kindness' for all in our world (sa.msaaraa).
