As to hold the Guru as Buddha and to follow his instruction is a fundamental practice, one cannot stop holding, but since the guru broke his samaya, he is not to be followed.
As DL has made it clear that he kicked out DS-practitioners, no longer accepting their discipleship, they are no longer his disciples and do not have to listen to his words, but empowering Guru is still a Buddha, no matter what.
Beyond what I said before, there are faults of logic.
So, according to you, from what you accurately call a fundamental practice, without explanations you announce that you should reject half of it and be chained by the other half ... how come you can do that?
What does it mean to hold somebody as a Buddha, if not to follow his instructions? What does it mean? To hold somebody as a Buddha has precisely that fonction, it actually means to follow his instructions. To visualize him bedecked in such or such way is insignificant compared with the only fonction that the Buddhas want to have, that is to teach us. I know that the tantric way is a very special way of teaching, but it is teaching nevertheless. So what does that mean to hold somebody as a Buddha if one cannot follow his instruction? What does it mean to be a Buddha in this case?
Well, to give an true example - from which we can make inferrals and interpretations - that cannot be overridden or proven wrong, since it is fundamental to all known traditions of Buddhism:
Buddha Shakyamuni, in Pali and Sanskrit Sutras, has given many instructions to
householders (read: men and women), that are not to be applied by
homeless ones (read: monks and nuns), and also many instructions to
homeless ones (read: monks and nuns) that are not to be applied by
householders (read: men and women). Nevertheless, neither party, householders or homeless ones, does dare to deny the absolute validity and authority of all those instructions, and still, they purposefully manage to "close their ears" to those instructions meant for the other party. If a monk would listen and follow the teachings that maintain that "the ultimate joy is one's offspring sitting in one's lap", that "one should spend 25% of one's business income by partying with one's family and friends", or that "one should adorn one's wife in luxury" (
necessary adornments, that is), and so forth, it would soon be the end of his career as a monk. And if a buddhist man would listen the teachings that expound the vices and depravity of womenkind, of sons and daughters, of music and dance, of everything human, would he remain even buddhist?
So, it s clear, that right from the beginning, Buddhism has had this interesting view that Buddha is Buddha, and always correct, but nevertheless, that He has provided different Dharma, different words, to differing audiences; often apparently conflicting , but still eternally true. Therefore, it is totally normal, from a Buddhist point of view, to
hold the Teacher as Teacher, and still close one's ears from His holy words, if there is a "dharmically good reason" for that
closure of ears to happen.
So you see,
we all are following Shakyamuni Buddha in a manner of necessarily not listening everything. Why would a Guru, since he is in Vajrayana necessarily
only a Buddha, be followed in a different manner?
You see?
What I have tried to advice to some of us unfortunate ones, is no more mysterious that that. Basic Buddhism, in fact.
