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.
