one thing i heavily recommend, especially in regards to kin memories: question everything. even if you want to be right? question it. are you certain of it? question again. make certain. someone tells you a certain thing was a certain way? question it. compare it to what you know, see what adds up and what doesn't. encourage healthy debate.
i'm not trying to be invalidating here, either. it's just that the mind sometimes jumps to conclusions on things based on prior knowledge. the sky is blue, the grass is green, angelic holiness is associated with white and gold. it can easily lead to human ideas being imposed onto nonhumans. also, certain concepts and constructs that existed then no longer can be perceived accurately, since we no longer experience them, and so the mind fills in the blanks or leaves a void. it makes things easier to comprehend in some cases, yeah, but it also leads to the reality getting skewed, and certain things being flat-out missing.
example: the gardens in heaven are almost always described as seeming exactly like human gardens. why? angels interacted with humans in this hunk of reality, but they also existed long before humanity did. we functioned under different laws of reality. even if you're of the belief that the realms are tied together, certain things that an angel can do simply don't work here, because our world's not constructed to work around it.
the two other major examples i can think of with this sort of thing are the libraries and the courts. every time i hear someone speak about the courts of heaven, they function almost the exact same the same as a human court, albeit sometimes with more judges. the jury, the trial, the sentencing, it's all so extremely human. i mean, one could argue that libraries are also a human construct and wouldn’t be a thing in heaven. and that's good! question it! question everything!
