By practicing according to the noble eight fold path one gets to a point where one sees the path and becomes ennobled.
The Venerable Ledi Sayadaw wrote :
Personality view is just another name for self view (attadiṭṭhi) in which the eye, ear, nose, tongue, body, and mind are regarded as “I” and “mine.” This view is held tenaciously by all ordinary people (puthujjana). When we say that the sense organs are tenaciously viewed as “I” and “mine,” this means that whenever a visible object is seen, people firmly and tenaciously believe “I see it, I see it.” The same is true of the other senses and their objects (with mind as the sixth). This is how personality view is established on the foundation of the six internal bases.
Let us take the example of a being who in past lives has made many stupid mistakes so that in his successive lives all these old evil kammas bom of personality view are attached to and always accompany his life continuity.
Proceeding in such a way, this being will in future existences also make foolish mistakes, thus making new evil kamma arising from personality view. So when personality view is extinguished, the results of past evil kamma leading to subhuman birth cannot arise, nor can more evil kamma be made. For this reason there is no longer any possibility of wandering-on in the deprived states; for such a person there are no more rebirths in the hells, the animal world, the ghost realm, and the demons—these are all extinguished. A person like this attains to his first experience of Nibbāna, called Nibbāna-with-the-grasped-at-groups-remaining (saupadisesa Nibbāna), meaning that for him the three rounds connected with the wandering-on in the states of deprivation are utterly extinct. He then becomes a noble one (ariya) in the noble supermundane plane, one to be reborn in successively higher planes of existence."
Right speech, action, and livelihood, which are the constituents of the morality group, are the factors to use forthe destruction of the third level of personality view, the transgressive level, when evil unwholesome kamma, fourfold of speech and threefold of bodily action, is, committed.
Right effort, mindfulness, and concentration, the factors of the concentration group, are the factors to use for the destruction of the second level of personality view, the obsessive level, when the threefold evil unwholesome kamma of the mind is made.
Right view and right intention, comprising the wisdom group, are the factors to use for the destruction of the first level of personality view, the latency level, which has always existed in the life-continuities of beings in the beginningless round of rebirths.
Whoever has been successful in establishing purity of moral conduct and purity of mind should then try to establish the wisdom group of right view and right intention so as to destroy the latency level of personality view. To have established these two path factors means the establishment in due order of the five purities of wisdom, which are:
purity of view, purity of overcoming doubt,
purity by knowledge and vision of what is and what is not the path,
purity by knowledge and vision of the practice-path,
purity by supermundane knowledge and vision.
If no steps are taken for the control of the mind, then unwholesomeness spreads from the obsessive level to the third level called the transgressive level (vitikkamabhūmi), the stage where unwholesome verbal or bodily kamma is made. These are, respectively, the fourfold verbal action (false speech, tale-bearing, harsh talk, and useless chatter), and the threefold bodily action (killing living creatures, taking what is not given, wrong conduct in sexual pleasures).
