Note that the main dogma of both schools, presumably, is directly from that of the historical Buddha Gotama or Gautama. Obviously the core teachings are identical and both agree with the same principle. For example, ‘the four noble truth = cat᷂tāri ariyasac᷂cāni’, ‘the Three Characteristics = tilak᷂khan᷂a’, ‘the rule of independent origination or the law of causation = pat᷂ic᷂casamup᷂pāda’, and ‘the laws of karma or karmic laws’. Merely that Mahayana school describes the law of causation more vividly and profoundly than of the Theravada school. It also introduced the new term used to describe ‘pat᷂ic᷂casamup᷂pāda’ as ‘suň᷂ňatā’.
There had been a clear development of Buddhism after the demise of the master, from the 2th- 3th Century B.C., from its orthodox doctrine [well known in Theravada or Hinayaha] to the new idea of Mahayana which some development of teachings, practices, and philosophical principles should be discussed and observed here;
Theravada (Orthodox doctrine)
