The tempter, death
Sanskrit/Pali 'mara' (death, destroyer), the personification of death, desire, and the forces that obstruct awakening.
Mara famously tried to stop the Buddha's enlightenment under the Bodhi tree, and continues to appear in Buddhist literature as the embodiment of temptation and doubt.
Under the Bodhi tree, Siddhartha resolved not to rise until he found the truth, withstood Mara's temptations, and awakened to the Four Noble Truths.
At eighty, the Buddha ate his last meal from Cunda, taught be a lamp unto yourselves, and passed between the twin sal trees at Kushinagar.
The Mahaparinibbana Sutta names four pilgrimage sites: Lumbini (birth), Bodh Gaya (enlightenment), Sarnath (first sermon), and Kushinagar (parinirvana).
