The Buddha is, in every respect, a teacher at the golden mean, ethically as well as philosophically. From the ethical standpoint, for example, the Buddha rejects two extremes: the way of sensual pleasures and the way of self-torture. From the philosophical standpoint he rejects eternity, as well as temporariness of an ego entity. Just so he rejects belief in an absolute identity and an absolute otherness of the various stages of the process of existence. He rejects the determinism, as well as the belief in chance. He rejects the belief in absolute existence and absolute non-existence; likewise in freedom of will, as well as in unfreedom of will.
All these things will become clear to one who understands the egolessness and conditioned nature of all phenomena of existence. On the understanding of these two truths depends the understanding of the entire doctrine of the Buddha. Hence the understanding and final penetration of the egolessness and conditionedness of all phenomena of existence are the necessary foundation to the realization of the noble eightfold path leading to deliverance from all vanity and misery, namely: right understanding, right thought, right speech, right bodily action, right livelihood, right effort, right mindfulness, and right concentration of mind. Only this golden middle path, based on these two kinds of right understanding, namely of "egolessness and conditionedness," can alleviate and destroy these vain illusions of "self" and craving, which are the root-causes of all war and bloodshed in the world. But without these two kinds of understanding there is no realization of the holy and peaceful goal pointed out by the Buddha.
