It's not up to you however.
It's up to ChNN, who has specifically stated time and time again, that to do Longde practice, you need to receive Longde transmission and teachings. In other words participate in person at the retreat site, or via closed webcast when that happens, on Longde.
Sorry I did not make myself clear. I was referring to what I believe is required to listen / view the Longde DVD, not to do the practice
You are exactly correct about practice, which is why I wrote,
"Of course, you should also do - exactly - whatever your teacher tells you to do."
I also wrote, "If you want to be official, you can request a lung of the teachings, and a short wang permission, in a vision or a dream, or in present reality," again referring to permission to view the DVD. Of course to do the practice, you need to receive Longde transmission and teachings, in person, or via a closed webcast.
I learned the Longde from ChNNR, in person, in several retreats, and have practiced the Longde in retreats. I pray that everyone who wants to receive the transmission in person, to be able to practice these wonderful teachings, can do so. Perhaps making the DVD available to those who are members and have had pointing out instruction, will lead those who buy the DVD to seek out and attend a Longde teaching, in person, or in a closed webcast. Perhaps this was the SSI thinking in making the DVD generally available in the "restricted" section.
