Many other scholars have expressed skepticism about the Buddhist claims of persecution by Pushyamitra. Étienne Lamotte points out that the Buddhist legends are not consistent about the location of Pushyamitra's anti-Buddhist campaign and his death. The "Ashokavadana" claims that Pushyamitra offered "dinara"s as a reward for killing Buddhist monks, but the "dinara" did not come into circulation in India before the 1st century CE. "Ashokavadana" also claims that Ashoka persecuted "Nirgrantha"s (Ajivikas), which is an obvious fabrication, considering that Ashoka's edicts express tolerance towards all religious sects. The Sri Lankan Buddhist text "Mahavamsa" suggests that several monasteries existed in present-day Bihar, Awadh and Malwa at the time Pushyamitra's contemporary Dutthagamani ruled in Lanka. This suggests that these monasteries survived Pushyamitra Shunga's reign.
