It’s worth it to take a close look here: this was not a nihilsm.
Nihilsm would be to deny even relative reality its’ reality. It is real - but, only relatively.
Now this is not a play of words: The “despicable neighbor” exists as a mental representational entity in my mind, thus it exists relative to my mind.
To other minds, the same physical phenomenon might exist relatively as a loving father, etc.
So per definition, relative reality exists only in relative perspective.
And absolute reality exists in independance of relative perspective.
Aren’t we constantly reifying a conglomerate of mental constructs of the world, made up of “despicable neighbors”, things we absolutely need to be happy, things we absolutely try to avoid because we think they make us unhappy?
Isn’t this the relative reality?
Understanding this relative reality of samsara as “relative” - i.e. not absolutely real - allows us to de-reify those mental constructs which cause us pain due to our relative relationships to them.
It would be nihilism to say they do not exist at all, but to understand that they are relative and dependant to our conditioned mind takes the “bite” out of those mental constructs.
Yes, I see no disagreement with that. I’ll share a recent lucid dream from two days ago as an analogy:
I become lucid in the dream. I am in a type of sewer system, but more of a rain water drainage system, nothing yucky. I look up and see an iron grill which blocks my path towards the surface. I stick my hands through the grill but it is solid. I say “This is a dream, this grill is not real”. The solidty vanishes instantly and I travel up to the surface.
In my relative reality, the grill was (intially) solid.
In absolute reality, it was a dream-grill and therefore ultimately not solid.
If I would have been unlucid, the realive reality of the grill would have stayed solid, although it was ultimately a dream-grill which has no solid reality!
Thus it is not an extremism (nihilism) to see through the relative reality of mental phenomena, even during daytime.
This view should not be misunderstood to mean that the physicality/causality of daytime phenomena have no effect on a sentient being.
A moving truck will still hit me, if I jump in front of it, even though the truck is a relative phenomenon.
