Here is a link to the finest exposition of the Seven Line Prayer I have seen on the Internet, from Lennart Warnemyr, in Sweden: http://www.warnemyr.com/tibetan/dorjetsigdun/index.html
Lennart Warnemyr took this seriously, and did it right. Should be required viewing for every Nyingmapa.
By the way, you can get the rather intriguing story on the Padmasambhava rupa, above, from http://www.shambhalashop.com/archives/surmang/padmasambhava.html
