I want to agree with that also. Apart from one bit: you calling it "absolute pseudoscience" is you making it "concrete"; is you presuming to understand his experience; is you thinking you know what it means.
Pseudoscience is something which claims to be scientific but isn't. I'm pretty sure that's not what's happening here.
That'd be like you saying you loved potato chips and someone telling you you can't be sure what love is and, anyway, that's "absolute pseudoscience" right there.
Man just wanna eat some crisps, ferchrissakes!
Still, the essence is fair enough, as a general guide: let's not get carried away with these marvellous experiences, even though they're about the best thing in the entire world - we don't want any Messiah complexes or delusions of grandeur.
And there's no sense that that's what he's doing either.
