Speech has levels of intent:
- frivolous
- simple transactional
- complex transactional
- rational/intellectual
- emotional/psychological
- philosophical
- spiritual/profound
Other levels could be added — performance, humor, recollection, story-telling, etc..
I believe a major value of religion is to expose and teach people how to speak and hear spiritual/profound speech.
That is a psycholinguistic core of most if not all religions. Religions are where most of us engage in spiritual/profound speech and where most of us learn it.
Consider an honest wholesome prayer as an example.
Buddhism engages spiritual/profound speech on many levels, but does not package any level as an absolute truth because the highest or deepest levels are not verbal and can only be experienced.
Religious profound speech leads us to experience the profundity of existence.
Remove all of the words and keep the experience and you have Buddhism.
