In Buddhism, a bodhisattva means either "enlightened (bodhi)
existence (sattva)" or "enlightenment-being" or, given the variant
Sanskrit spelling satva rather than sattva, "heroic-minded one (satva)
or enlightenment (bodhi)." Another translation is "Wisdom-Being".
It is the name given to anyone who, motivated by great compassion,
has generated bodhicitta, which is a spontaneous wish to attain
Buddahood for the benefit of all living beings.
