And of course, the meaning of the word itself is to have an earthshaking realization, a momentous revelation, an "ah-hah" moment or other important and unexpected happening - like Paul had on his way to Damascus when an angel scared him half to death by telling him to stop persecuting Christians and join the club. So you could go scare someone into being good! It's kind of like that head slap you see in the commercials - "Should have had a V8!"
But then you know it is an ancient remembrance of the day the Magi visited Jesus, right? Why it's in all our Christmas creche scenes! I'm surprised you didn't remember it, really! And what do you on this date? Well, you could break out the gold, frankencense and myrrh - but that might also break the bank! You would wish everyone peace, love and health, supposedly three ancient friendly wishes from those three lovely wise guys!
