This is the Dzogchen forum. The comment was directed to a specific view that could be a deviation in the practice of Dzogchen - not a suggestion that anyone cultivate desire or attachment to some imagined goal - to say nothing of belief which is useless in this context.The Buddha recommended relinquishing all cravings, desire, becoming, attachment, to what we call 'our experience'. This also means relinquishing the desire for enlightenment and the belief in any satisfaction in things. Are you up for that?
Dzogchen purports to be a vehicle of liberation in one skull. If someone considers themselves a practitioner, it would behoove them to at least take the teaching on its own terms. I stand by my statement the view that liberation in one life is "bullshit", or "I'm a jerk in samsara and will never amount to anything at all, poor despicable me" is an anathema in the practice of Dzogchen.
For the record, I'm not saying Javier really holds this view. His comment was light-hearted and made in the context of a lot of discussion back and forth about emanations and different types of realization. I quoted it to make this point because I've noticed in myself for sure, and I at least suspect in others based on these types of comments, a tendency to bring these types of views to bear in the practice of Dzogchen.
It's not that helpful to cherry pick specific quotes and then erect a straw man as you're doing in this case, taking something very context specific and applying it to general Mahayana. The use of scare quotes notwithstanding, we must use language to communicate and I think my comment was, or should be pretty obvious to the audience for which it's intended.
