It means that if you don't know something, then it can't affect the your view of the world. For example, if a person is completely ignorant of the sciences, the contradicting information can't challenge their belief in whichever religion they're a part of.
I think it means that if you don't know about something bad that may be going on in the world or being said about you behind your back etc, then you can carry on your own merry little way happily - so put another way being ignorant to certain horrid facts means you can continue being blissfully happy.
if you don't know that there is a problem, nothing will change..you'll just continue being happy
If ignorance is a blissful state then what happens when your ignorance causes such a rift in your life it changes everything completely? The are always consequences to everyone’s actions and often there are also consequences to non-action as well. I would classify ignorance as non-action towards whatever it is you’re ignorant about.
