But, as Ram Das once quipped: “The most difficult thing is to remember – to remember!”
This reminds me that "To be there is to remember" which to me has a strong meaning due to (sometimes prolonged, intense) dissociation: Even though I might have been physically present, if I cannot remember, I wasn't really there. (Which can be a comfort.)
I doubt any of that is helpful.
What you said was indeed helpful, because this similar sentence already pops up in my mind repeatedly, and I can use it as a cue: I can attach a 2nd meaning to it, namely that, eventually, I will not get another chance to remember anything at all (in the sense Cassius explained for PD02).
PD02's warning about no more sensations doesn't bother me all that much (it's too physical, too body-focused; to me, no more sensations actually sounds nice — maybe that's another reason why I had misinterpreted it as a PD01 reprise?); but that I will not get to remember anything anymore, and by extension not get to think anything again, that really reaches me. (Which makes it a bit unpleasant in the moment, but I feel it will ultimately proof to be very helpful!)
