I wondered about that, too, and I think that’s why they said “their” present. I think the bottom line is, you can’t manipulate time in a way that you can take advantage of it in an incarnation, like going back in time when Amazon first opened and stock was cheap, so you could buy it up. I do know time is different in the soul realms, described as circular, rather than linear, as it is here, but I just can’t wrap my head around it. I have nothing to compare it to in terms of experience. It gives me a headache when I try!
