Wish I could say more but I'm out the door for work. Zen as part and parcel of Mahayana Buddhism, places emphasis on the bodhisattva, one who has attained enlightenment, and choses to stay and care for the rest of the suffering world, The ultimate act of compassion.
I'm not saying you are enlightened or not. What I am saying is I agree with ET in saying the lesson in the path of the bodhisattva is that we can too strive in life for giving as much compassion as we can to those 'less enlightened' then ourselves.
Laughing at someones pain isn't good in other words, in most cases.
Laughing at your own, is safer ground.
Something to maybe elucidate.
Bodhisattva Mind/Action
