@Zhalmed Pawo,
I agree with and really like your last paragraph, so pragmatic.
Nevertheless, when it comes to describing the Guru/disciple relationship, are you saying that samaya would arise automatically if somebody had “attended” empowerments from him?
Many Westerners probably think that because they physically attended the initiations … they are chained by samaya. But this is not as automatic as it seems.
“If you have taken empowerments”, you say, and this is correct. But we should specify that not because of being present at an empowerment one is taking the empowerment.
Not to mention true refuge, at least a forced form of bodhicitta and a good rational comprehension of shuñata are mandatory to being suitable to receiving an empowerment. And among the throngs of attendees of so many empowerments, not all of them had these qualifications. How many non Buddhists attended because they were “searching” in some general variegated spiritual path! These definitely did not enter into a samaya because they didn’t have true refuge at the time, they weren’t even Buddhists.
Moreover, there is a tricky question that is subject to interpretation. If you go to a Guru, believing that he is this immaculate type of person, and after the fact, years later, you discover that, had you known about certain serious deeds you would not have taken the empowerment, then that samaya is subject to discussion, because you were giving yourself to a certain Guru, who in reality was not there. Food for thought ... In Dharma, (and in life in general) everything depends on the mind, and foremost on the motivation. There are no automatic, unconscious commitments possible. So maybe some people were establishing a samaya with a Deity, with all the Buddhas, but not necessarily with the one person who was in front of them ...
For those tormented by this matter, I would say, grab for yourselves the old Latin saying, "in dubbio pro reo". If in doubt, then the decision has to be favorable to the accused. In this case I really would like to deliver from unfair shackles those who regret having been there, at all those empowerments of older, innocent times.
On the other hand, your last paragraph is valid both ways. There is no such thing as a one way samaya. If you are a Protector’s practitioner you are not in any samaya with the Dalai Lama, no matter how many true empowerments you received from him. He broke the samaya with you, he abandoned you, whether you like it or not. He does not want you. Period. So why insist?
