Full context:   According to Keown, it is possible to reinterpret the Buddhist doctrines such as the Four Noble Truths, since the final goal and the answer to the problem of suffering is nirvana, and not rebirth. Some Western interpreters have proposed what is sometimes referred to as "naturalized Buddhism". It is devoid of rebirth, karma, nirvana, realms of existence, and other concepts of Buddhism, with doctrines such as the Four Noble Truths reformulated and restated in modernistic terms.[note 53][note 54] This "deflated secular Buddhism" stresses compassion, impermanence, causality, selfless persons, no Boddhisattvas, no nirvana, no rebirth, and a naturalist's approach to well-being of oneself and others.
