Personally I just needed the space. I've also had to get rid of a lot of things I own several times so it's not so alien to me. But maybe you are linking this to some sort of decision making process - as if it's the physical acting out of the decision to just focus on Dzogchen. Of course that might be totally wrong.
For me, it's like I'll have read some version of how things 'really' are in one book, then something else in another and another. I don't retain it all and it becomes confused and so I'll find myself thinking I want to learn or study or whatever and there's just a mental block up there because it seems a bit hopeless, like I'm chipping away at a block of marble with a toothpick. The different dzogchen books I have will just briefly contrast views of different traditions in order to show what is different and this is enough to suffice. If I am focusing on dzogchen view, I don't think for me
it is useful to know the ins and outs of other traditions. I think it's just too much to keep track of. Sometimes I will be reading a book and suddenly it will hit me how much I have learned in the past 15 years when I first bought Robert Thurman's "Essential Tibetan Buddhism" book (and closed it halfway through feeling as though trying to learn this tradition was a lost cause), but still with all I have learned, I know there is a whole bunch of conceptual stuff I don't know about the particulars of various practices, etc. And I don't see the point of trying to learn that if it is not really what I intend to do with the rest of my life. If there is no end to concepts, I am content doing things as simply as possible. And if my practice is not really about thinking but more about doing and experience, then it makes sense not to spend so much time invested in thoughts, it seems to me. Additionally, I used to just feel conflicted about what is right for me in the past (eg. since I am not a great dzogchenpa, should I invest this time in dzogchen teachings/practices or in vajrayana methods? Etc.).
