You have intelligence, there is no doubt. Human being must have intelligence. But that intelligence is given to him for getting out of the clutches of birth, death, old age and disease. He's not utilizing that intelligence for that purpose, therefore duskrtina. Intelligence he has got. We don't say that modern world, they are unintelligent, fools. No, they have got intelligence. But the intelligence is being utilized for duskarya, which he should not have done. Duskarya. Karya and duskarya - work and bad work.
