It is like the case of a baby being given milk to drink.* Even though the baby may not understand the flavour of milk, the milk naturally nurtures the baby's growth. Similarly, if a physician gives medicine to a sick person, even though the sick person may not know the origin and nature of the medicine, if he takes it, then in the natural course of events his illness will be cured. But if he objects that he does not know the origin of the medicine that the physician gives him and for that reason declines to take it, do you think his illness will ever be cured? Whether he understands the medicine or not, so long as he takes it, he will in either case be cured.
