Important Information:
According to Major Rock Edict VIII of Emperor Ashoka, he describes his personal involvement in religious pilgrimages — which he refers to as "Dhamma-yatras" instead of royal hunting expeditions.
One specific pilgrimage he mentions is to a Buddhist site, which historians identify as Sarnath, the place where Buddha gave his first sermon (Dhammacakkappavattana Sutta).
Lumbini: Mentioned in Rummindei Pillar Edict, not in Major Rock Edict VIII.
Bodhgaya: No direct mention by Ashoka in the edicts.
Kushinagar: Also not mentioned in any of Ashoka's known edicts.
