Doubt is not a disease but merely a symptom of a lack of what we in our tradition call the View, which is the realization of the nature of mind, and so of the nature of reality. When the View is there completely, there will be no possibility for the slightest trace of doubt, for then we'll be looking at reality through its own eyes. But until we reach enlightenment there will inevitably be doubts, because doubt is a fundamental activity of the unenlightened mind, and the only way to deal with doubts is neither to suppress nor indulge them.
