How is Hun and Po relevant to Neidan?

[MadePossible]

I'm looking preferably for direct quotes mentioning the involvement of Hun and Po in the neidan process. Their concepts seem so abstract that it's hard to understand what their function is.

 

Sorry if this has been asked before, I tried searching but it seems the search function doesn't work? It returns with zero results when searching 'Hun and Po'.

 I will let those more learned than me answer about hun and po  - but the search function on here has always been weak and sometimes it’s better to use google to search - something like ‘the DaoBums hun and po’ might work.
