The Parable of the Wheat and the Tares is a good place to start; Jesus telling his disciples about the counterfeit 'tares' which were planted by the enemy 'among' the wheat. I'm not a mathematician, but I think the word among tells us that 1/3 would be tares. also look up the term 'hylic', one of the three types of souls/lowest form/connected to the material world.
