A large problem in the study of early Buddhism is the relationship of dhyana and what else?
A core problem in the study of early Buddhism is the relation between dhyana and insight. Schmithausen, in his often-cited article On some Aspects of Descriptions or Theories of 'Liberating Insight' and 'Enlightenment' in Early Buddhism notes that the mention of the four noble truths as constituting "liberating insight", which is attained after mastering the Rupa Jhanas, is a later addition to texts such as Majjhima Nikaya 36.[page needed]
Like the Pagan Empire, Ava, Hanthawaddy and the Shan states were all multi-ethnic polities. Despite the wars, cultural synchronisation continued. This period is considered a golden age for Burmese culture. Burmese literature "grew more confident, popular, and stylistically diverse", and the second generation of Burmese law codes as well as the earliest pan-Burma chronicles emerged. Hanthawaddy monarchs introduced religious reforms that later spread to the rest of the country. Many splendid temples of Mrauk U were built during this period.
