Dear sisters and brothers, we realize the importance of light when we see darkness.We realize the importance of our voice when we are silenced.In the same way, when we were in Swat, the north of Pakistan, we realized the importance of pens and books when we saw the guns.The wise saying, "The pen is mightier than the sword." It is true.The extremists are afraid of books and pens.The power of education frightens them.They are afraid of women.The power of the voice of women frightens them.This is why they killed 14 innocent students in the recent attack in Quetta.And that is why they kill female teachers.That is why they are blasting schools every day because they were and they are afraid of change and equality that we will bring to our society.And I remember that there was a boy in our school who was asked by a journalist why are the Taliban against education?
