QUOTE : The actions that accompany the four truths describe the trajectory of dharma practice: understanding anguish leads to letting go of craving, which leads to realizing its cessation, which leads to cultivating the path. These are not four separate activities but four phases within the process of awakening itself. Understanding matures into letting go; letting go culminates in realization; realization impels cultivation. This trajectory is no linear sequence of "stages" through which we "progress." We do not leave behind an earlier stage in order to advance to the next rung of some hierarchy. All four activities are part of a single continuum of action. Dharma practice cannot be reduced to any one of them; it is configured from them all. As soon as understanding is isolated from letting go, it degrades into mere intellectuality. As soon as letting go is isolated from understanding, it declines into spiritual posturing. The fabric of dharma practice is woven from the threads of these interrelated activities, each of which is defined through its relation to the others.
