It would seem to me that the compassion concept could be broken down to even simpler parts – active and passive.

Active compassion begin the “moving” and passive being the “feeling”.

Looking at the etymology of the word in latin, com means “together” and of course passion means “to suffer” – both roots implying an active and passive form.

Taking the thought further it seems to me that the active part is associated with giving, and the passive part receiving… we come together by giving our time, resources, and emotions in a way that benefits the individual, group, or cause we feel empathy for. As we give, we also receive by ’syncing’ our emotions with the same, thereby also partaking in the suffering.

Kind simple I guess…
