I'm not sure we should even want to 'get it all back'; we might end up with something like "Groundhog Day" (the movie). It would almost defeat the purpose of existence. Read my signature quote.
On the one hand, I agree with you and I know your signature quote well. I've known that quote for many years before I saw you quote it.
However, I think the purpose of existence is not linear, as are many of the phenomena in this world that we describe linearly in this density.
I do not mean that you are experiencing the same moments over and over again. I mean something higher, something that is out of time.
I can see you are suffering and I understand that you are suffering. You learn. The point, however, is that I do not put infinite hope in this quote. We know well the suffering caused by time, but the unknown is suffering that takes place outside of time.
And from some unfathomable depth of intuition, it seems to me that only breaking time will lead us to understand everything that we are going through in this world. This time seems cruel, doesn't it? But what is beyond time is the limit for me. The boundary beyond what is materialistic and what constitutes the upper world. This is one of the reasons I am so interested in time.
When I see a person experiencing a loss, I understand that person more than perfectly. Every day I experience a loss. This day will never happen again. Something has passed with no way to return. But I feel there is much more to this than we think today.
Each loss can be a new hope. I watch it closely.
