Hi michaela, I see it this way -
1. Scenario A - the attendants already had negative karma dormant. In that life, or in a future life, the negative karma would have fruitioned so they harmed another being without any positive result. At least in this instance, their negative actions resulted in a Dharmapala. Im not saying murder is OK! Im just saying, given their negative karma to be able to kill someone, it was only a matter of time they were going to commit an action of equal negative karma...might as well commit an action that resulted in a positive result. Im just thinking back to Buddha Shakyamuni and how he killed one person, to save 499 people on a ferry.
2. Scenario B - alternatively, you can also see the attendants as manifestations of Tulku Dragpa Gyaltsen. This is just pure speculation, Ive not read anything to confirm this. Im only bringing it up because I know enlightened beings can manifest as both student and teacher.
As to your other question, to me, a swear is a matter of the heart. If I make a commitment to my lama and it resides in my heart, whatever I utter, the commitment is still there. Meaning I might unswear verbally, but in my heart my commitment is still there. Of course, Id rather NOT have to unswear but if I really have to, then I have to...in this instance Im thinking of monks who were held at gunpoint by Chinese troops and forced to rape nuns.
To me, it is the reason why many lamas are revealed to still be secretly practising Dorje Shugden after so many years. They appeared to have given up the practice, but in reality still hold Dorje Shugden in their hearts. Case in point, the former 101st Gaden Tripa and Samdhong Rinpoche. After his term is completed, the Gaden Trisur defects to Shar Gaden and after many years, Samdhong Rinpoche says he only does what his root guru Trijang Rinpoche tells him to do hmmmm
But if you cant buy that, then lets use your logic of intent, execution, completion and satisfaction
if I unswear (execution and completion), but my intent and satisfaction to unswear are missing, then the action is not complete. As I see it, in that case, the samaya is not fully severed and is repairable.
So why create more bad karma? The way I answer this for myself is that for many of the people who are confused, they were going to be confused anyway - if something so simple as a secular government telling them the practice is banned, can shake their guru devotion, were they REALLY devoted to their guru and practice in the first place? If the ban wasnt going to shake their faith, something else later wouldve.
