As I’m trying to understand –Ontology-, this research gives some interesting insights and explains well the ontological approach. You may download the paper and I’ve included the conclusion.
On the basis of this survey of major issues in Buddhist
ontology, we conclude that while genuine differences between
Buddhist and Bahá’í ontology exist, on a significant number of
the most fundamental issues, they agree and that on others
where there is no outright agreement, there is convergence.
Ontologically speaking, the two religions differ more in
emphasis, on what they choose to elaborate, than in basic
ontological doctrines per se. That is exactly what we would
expect from the Bahá’í teaching that differences among
religions arise not from their foundational principles but from
the time and circumstances of their revelation.200 Our findings
thus support Bahá’u’lláh’s teaching on the “fundamental
oneness of religion.” (PUP 175)
