Joseph Campbell said this quote
“ When the Buddha declares there is escape from sorrow, the escape is Nirvana, which is not a place, like heaven, but a psychological state of mind in which you are are released from desire and fear. And your life becomes harmonious, centered and affirmative. Even with suffering. The Buddhists speak of the bodhisattva - the one who knows immortality, yet voluntarily enters into the field of the fragmentation of time and participates willingly and joyfully in the sorrows of the world. ”
