In your letter, you emphasized that Vajrayana needs to be properly introduced. What I understood from your letter is that even though an authentic Vajra Master can pretty much do whatever they see fit, the relationship needs to be properly established. You say the Vajrayana teachings lay this out clearly. From this point of view, I would say I was not properly introduced, neither to the Vajryana nor the Dzogchen Samaya. If I manage to get a good lawyer, I think I have good chance to argue in Vajrayana court that my contract was not valid.
