The use of Buddhist sources in reconstructing the life of Ashoka has had a strong influence on perceptions of Ashoka, as well as the interpretations of his edicts. Building on traditional accounts, early scholars regarded Ashoka as a primarily Buddhist monarch who underwent a conversion to Buddhism and was actively engaged in sponsoring and supporting the Buddhist monastic institution.Later scholars have tended to question this assessment. The only source of information not attributable to Buddhist sources – the Ashokan edicts – make only a few references to Buddhism directly, despite many references to the concept of dhamma (Sanskrit: dharma). Some interpreters have seen this as an indication that Ashoka was attempting to craft an inclusive, poly-religious civil religion for his empire that was centered on the concept of dharma as a positive moral force, but which did not embrace or advocate any particular philosophy attributable to the religious movements of Ashoka's age such as the Hindus, Jains, Buddhists, or Ajivikas.Most likely, the complex religious environment of the age would have required careful diplomatic management in order to avoid provoking religious unrest. Modern scholars and adherents of the traditional Buddhist perspective tend to agree that Ashoka's rule was marked by tolerance towards a number of religious faiths.
