Buddhism and Christianity, especially in their radicalized forms, share deep affinities. This chapter focuses on affinities shared regarding the Christian Kingdom of God and Buddhist nirvana and the Christian conception of the kenosis (emptying) of God and Buddhist sunyata (emptiness) as a fundamental characteristic of reality. This chapter pays special attention to Nagarjuna, The Threefold Lotus Sutra, Dōgen, and the Kyoto School.
