Ignorance prevails as long as the will remains cheated by its own offspring or its own image, consciousness, in which the knower always stands distinguished from the known. The cheating, however, cannot last, the will wishes to be enlightened, to be free, to be by itself. Ignorance always presupposes the existence of something outside and unknown. This unknown outsider is generally termed ego or soul, which is in reality the will itself in the state of Ignorance. Therefore, when the Buddha experienced Enlightenment, he at once realised that there was no Atman, no soul-entity as an unknown and unknowable quantity. Enlightenment dispelled Ignorance and with it all the bogies conjured up from the dark cave of ego disappeared. Ignorance in its general use is opposed to knowledge, but from the Buddhist point of view in which it stands contrasted to Enlightenment, it means the ego (_ātman_), which is so emphatically denied by the Buddha. This is not to be wondered at, seeing that the Buddha’s teaching centred in the doctrine of Enlightenment, the dispelling of Ignorance. Those who only see the doctrine of non-atman in Buddhism and fail to inquire into the meaning of Enlightenment are incapable of appreciating the full significance of the Buddha’s message to the world. If he simply denied the existence of an ego-entity from the psychological point of view after reducing it into its component factors, scientifically he may be called great as his analytical faculties stood far above those of his contemporaries in this respect; but his influence as a spiritual leader would not have reached so far and endured so long. His theory of non-atman was not only established by a modern scientific method, but essentially was the outcome of his inner experience. When Ignorance is understood in the deeper sense, its dispelling unavoidably results in the negation of an ego-entity as the basis of all our life-activities. Enlightenment is a positive conception, and for ordinary minds it is quite hard to comprehend it in its true bearings. But when we know what it means in the general system of Buddhism, and concentrate our efforts in the realisation of it, all the rest will take care of themselves, such as the notion of Ego, attachment to it, Ignorance, Fetters, Defilements, etc. Moral Conduct, Contemplation, and Higher Understanding—all these are meant to bring about the desired end of Buddhism, that is, Enlightenment. The Buddha’s constant reiteration of the theory of causation, telling his disciples how when this is cause that is effect and how when cause disappears, effect also disappears, is not primarily to get them acquainted with a kind of formal logic, but to let them see how Enlightenment is causally related to all human happiness and spiritual freedom and tranquillity.
