Those of compassionate love have, through prajna, completely severed all self-cherishing. They will not want to enter a personal nirvana because they dearly care for every being. Hence, by reliance upon these means to enlightenment i.e. wisdom and compassion, the deeply-realised abide neither in samsara nor the quiescence of a personal nirvana.

-- Maitreya, Uttaratantra Shastra
