The Noble Eightfold Path
The practical method that the Buddha taught is called the Noble Eightfold Path. By following this path fully one can gain insight knowledge, leading to attainment of the path and its fruition, which means to realise nibbæna, the cessation of suffering. If
one can attain nibbæna, one will have no doubt about the real Dhamma, since one has personally realised the goal of Buddhism
To attain nibbæna one must develop insight knowledge through the constant practice of mindfulness. The eightfold path is a gradual path that must be cultivated through training in morality, concentration, and wisdom. If one practises the path, confidence in the power of mindfulness will steadily grow, but doubt is not completely eradicated until one attains the first path and its fruition with the realisation of nibbæna.
Before that life-changing experience, however, one will attain
the lower stage of insight knowledge — “Purity by overcoming
doubt” — which will confirm one’s faith in the importance of
practice. Even at this early stage of insight, a meditator will
have firm confidence in the true Dhamma, and will understand the need to develop the practice further. He or she will no longer be content with outward forms of Buddhism.
The Noble Eightfold Path can be divided into three trainings: morality, concentration, and wisdom. These should be practised in parallel. To be perfect in morality before trying to develop concentration and insight is not essential, but one should live by sound moral principles.
