Television has done us great damage.
It's especially destructive for children. A seven-year-old child came to the hermitage once. I saw the demon of television speaking through the child's mouth, exactly as demons speak through the mouth of the possessed. It was like a baby born with teeth. It is not easy to find normal kids; they are turning into little monsters. And you see they don't get to think for themselves, they only repeat what they have heard and seen on television. That's why they have come up with television to begin with: to make people numb and dumb, so that they will take what they hear and see on television for a fact and act accordingly.
We should be trying to lead our children to seek to turn on the "spiritual television"
[Mothers must be helped to] understand that television dulls their children's minds. They lose the ability to think on their own, to think critically—not to mention the damage it causes to their eyesight. And we are talking about man-made television. But there is another kind—a spiritual television. When people uproot their old self, and the eyes of the soul are cleansed, they can see into the future without the aid of any machines. Have they told their children about this other kind of television? If they won't, these boxes will make our children dumb."
