I thank Vishwontarji for mentioning about 8 Noble Paths. But everything Buddha taught was only for two purposes. As I mentioned earlier, Budhha was totally (exclusively) concerned with only 2 problems: 1. Dukkha:suffereing, unsatisfactoriness - disharmony. 2. Nirodha: elimination or remediation or cessation of suffering. Therefore, if you want to practice Buddhism, you have to understand/practice Buddhism for the purpose of only above two aspects (parameters or domains). You can develop deep concentrations to acomplish many things in the world, even Terrorism by Prachanda and Baburam. But what Vishwontar ji is talking is the similar concentration is needed to reach Nirvana (cessationof Sufferings). And to develop such a deep concentration, Buddha realized that Pure Discipline is required. Of course Maobadis in Nepal perhaps had discipline maintained by Prachanda and Baburam, and therefore they become so successful while hiding in the mountains and jungles. However, that discipline, as we know, is the IMPURE one. It was for the wrong cause which subscribed to killing everytboy who came against their Prachanda Path.
