Buddhism, as sin is understood in some religions. The root of all evil is ignorance (avijjā) and false views (micchādiṭṭhi). It is an undeniable fact that as long as there is doubt, perplexity, wavering, no progress is possible. It is also equally undeniable that there must be doubt as long as one does not understand or see clearly. But in order to progress further it is absolutely necessary to get rid of doubt. To get rid of doubt one has to see clearly.
