The Noble Eightfold Path, discovered by the Buddha Himself, is the only way to Nirvana. It avoids the extreme of self-torture that weakens ones intellect and the extreme of self-indulgence that retards ones spiritual progress.
(a) the endeavor to discard evil that has already arisen.
(b)the endeavor to prevent the arising of unrisen evil.
(c)the endeavour to develop that good which has already arisen.
(d)the endeavour to promote that good which has not already arisen.
Effort is needed to cultivate Good Conduct or develop one’s mind, because one is often distracted or tempted to take the easy way out of things. The Buddha teaches that attaining happiness and Enlightenment depends upon one’s own efforts. Effort is the root of all achievement. If one wants to get to the top of a mountain, just sitting at the foot thinking about it will not bring one there. It is by making the effort of climbing up the mountain, step by step, that one eventually reaches the summit. Thus, no matter how great the Buddha’s achievement may be, or how excellent His Teaching is, one must put the Teaching into practice before one can expect to obtain the desired result.
Meditation means the gradual process of training the mind to focus on a single object and to remain fixed upon the object without wavering. The constant practice of meditation helps one to develop a clam and concentrated mind and help to prepare one for the attainment of Wisdom and Enlightenment ultimately.
