Please find below a link to the Chakra Opening Exercises Audio (AAC).
This recording is available on my website via the press pack page. Its circa 27 mins long
The PDF file (on the same press pack page) is not so detailed and includes the use of the mountaineering harness and rope to ground one, but I really feel that is is not necessary for this exercise.
I make the minor mistake of illustrating the point of origin of the sacral chakra after extending and rotating it, but correct that in the other chakras.
I do feel however that people who use this will know the basic knowledge of the chakra locations.
