One can think of the different ideas, agitated ones, antagonized ones, blunted ones, ignorant ones, drunken with falsehood or with jealousy, all sorts of poisons; there are many in this world. And it is only one power, the power of your sympathy, that assimilates all poisonous influences. It assimilates them; it takes away their poison, and it does not hurt you.
You sooner or later purify them, revivify them, melt them, mould them, and direct them toward their purpose of life.
