The eight factors of the Noble Eightfold Path are not steps to be followed in sequence, one after another. They can be more aptly described as components rather than as steps, comparable to the intertwining strands of a single cable that requires the contributions of all the strands for maximum strength. With a certain degree of progress all eight factors can be present simultaneously, each supporting the others. However, until that point is reached, some sequence in the unfolding of the path is inevitable. Considered from the standpoint of practical training, the eight path factors divide into three groups: (i) the moral discipline group (silakkhandha), made up of right speech, right action, and right livelihood; (ii) the concentration group (samadhikkhandha), made up of right effort, right mindfulness, and right concentration; and (iii) the wisdom group (pannakkhandha), made up of right view and right intention. These three groups represent three stages of training: the training in the higher moral discipline, the training in the higher consciousness, and the training in the higher wisdom.
The order of the three trainings is determined by the overall aim and direction of the path. Since the final goal to which the path leads, liberation from suffering, depends ultimately on uprooting ignorance, the climax of the path must be the training directly opposed to ignorance. This is the training in wisdom, designed to awaken the faculty of penetrative understanding which sees things "as they really are." Wisdom unfolds by degrees, but even the faintest flashes of insight presuppose as their basis a mind that has been concentrated, cleared of disturbance and distraction. Concentration is achieved through the training in the higher consciousness, the second division of the path, which brings the calm and collectedness needed to develop wisdom. But in order for the mind to be unified in concentration, a check must be placed on the unwholesome dispositions which ordinarily dominate its workings, since these dispositions disperse the beam of attention and scatter it among a multitude of concerns. The unwholesome dispositions continue to rule as long as they are permitted to gain expression through the channels of body and speech as bodily and verbal deeds. Therefore, at the very outset of training, it is necessary to restrain the faculties of action, to prevent them from becoming tools of the defilements. This task is accomplished by the first division of the path, the training in moral discipline. Thus the path evolves through its three stages, with moral discipline as the foundation for concentration, concentration the foundation for wisdom, and wisdom the direct instrument for reaching liberation.
Perplexity sometimes arises over an apparent inconsistency in the arrangement of the path factors and the threefold training. Wisdom -- which includes right view and right intention -- is the last stage in the threefold training, yet its factors are placed at the beginning of the path rather than at its end, as might be expected according to the canon of strict consistency. The sequence of the path factors, however, is not the result of a careless slip, but is determined by an important logistical consideration, namely, that right view and right intention of a preliminary type are called for at the outset as the spur for entering the threefold training. Right view provides the perspective for practice, right intention the sense of direction. But the two do not expire in this preparatory role. For when the mind has been refined by the training in moral discipline and concentration, it arrives at a superior right view and right intention, which now form the proper training in the higher wisdom.
Right view is the forerunner of the entire path, the guide for all the other factors. It enables us to understand our starting point, our destination, and the successive landmarks to pass as practice advances. To attempt to engage in the practice without a foundation of right view is to risk getting lost in the futility of undirected movement. Doing so might be compared to wanting to drive someplace without consulting a roadmap or listening to the suggestions of an experienced driver. One might get into the car and start to drive, but rather than approaching closer to one's destination, one is more likely to move farther away from it. To arrive at the desired place one has to have some idea of its general direction and of the roads leading to it. Analogous considerations apply to the practice of the path, which takes place in a framework of understanding established by right view.
The importance of right view can be gauged from the fact that our perspectives on the crucial issues of reality and value have a bearing that goes beyond mere theoretical convictions. They govern our attitudes, our actions, our whole orientation to existence. Our views might not be clearly formulated in our mind; we might have only a hazy conceptual grasp of our beliefs. But whether formulated or not, expressed or maintained in silence, these views have a far-reaching influence. They structure our perceptions, order our values, crystallize into the ideational framework through which we interpret to ourselves the meaning of our being in the world.
These views then condition action. They lie behind our choices and goals, and our efforts to turn these goals from ideals into actuality. The actions themselves might determine consequences, but the actions along with their consequences hinge on the views from which they spring. Since views imply an "ontological commitment," a decision on the question of what is real and true, it follows that views divide into two classes, right views and wrong views. The former correspond to what is real, the latter deviate from the real and confirm the false in its place. These two different kinds of views, the Buddha teaches, lead to radically disparate lines of action, and thence to opposite results. If we hold a wrong view, even if that view is vague, it will lead us towards courses of action that eventuate in suffering. On the other hand, if we adopt a right view, that view will steer us towards right action, and thereby towards freedom from suffering. Though our conceptual orientation towards the world might seem innocuous and inconsequential, when looked at closely it reveals itself to be the decisive determinant of our whole course of future development. The Buddha himself says that he sees no single factor so responsible for the arising of unwholesome states of mind as wrong view, and no factor so helpful for the arising of wholesome states of mind as right view. Again, he says that there is no single factor so responsible for the suffering of living beings as wrong view, and no factor so potent in promoting the good of living beings as right view (AN 1:16.2).
In its fullest measure right view involves a correct understanding of the entire Dhamma or teaching of the Buddha, and thus its scope is equal to the range of the Dhamma itself. But for practical purposes two kinds of right view stand out as primary. One is mundane right view, right view which operates within the confines of the world. The other is supramundane right view, the superior right view which leads to liberation from the world. The first is concerned with the laws governing material and spiritual progress within the round of becoming, with the principles that lead to higher and lower states of existence, to mundane happiness and suffering. The second is concerned with the principles essential to liberation. It does not aim merely at spiritual progress from life to life, but at emancipation from the cycle of recurring lives and deaths.
