A child is there; you call him pure. He gets angry, he has greed, so why do you call him pure? What is pure in childhood? Innocence! There is no division in the mind of a child. The child is unaware of any division into what is good and what is bad. That unawareness is the innocence. Even if he gets angry, he has no mind to be angry, it is a pure and simple act. It happens, and when anger goes, it goes. Nothing is left behind. The child is again the same, as if the anger has never been there. The purity is not touched; the purity is the same. So a child is pure because there is no mind.
