Huang-t'ing Ching meditation

[soaring crane]

Hi,

 

I'm interested in the Huang-t'ing Ching meditation method from Wei Huacun/Wei Hua-ts'un. I've had Michael Saso's book, "The Gold Pavillion" for a number of years now and although I wholeheartedly trust his translation, the techniques are pretty difficult to glean from it. Are there any other guides available that go a little more in-depth into the methods themselves?

 

Also, any good informative books regarding the Highest Pure sect of Taosim?
