Very many acolytes exist re The Rainbow Bridge. Across all demographics and faux-enlightenments.

(And.. since it is an unvarnished-Miracle! for All to See:
"that there IS Anything At All / and then: some creature to Notice that fact?")

Loss of a/any beloved pet created the Need for this icon.
And, I note--even many of the over-educated / or the oft emotionally tongue-tied--cleave to that idea of,

(A perfectly natural/disdainful response, too: to the purely-mechanical nature of George Booleishness, IMO)

I deem this actually less-silly than.. most of the myths of the Sigma-Corporate-religion-things.

Certainly-corrrect underlying-force ... behind there Being a, er 'Universe' at all. Why Else?

Squeak! ... how unSpeakably great to. see. you. again! . . . just have to ask you about, what you really Meant when you ____?

Jeez.. shades of Manfred

I, Meta-
I contain multitudes. Too.

--unless you're someone's pet.

Don't be Thor, though--but you seem to have the wrong bridge in mind.
(Have not enquired if--when one is a-Rainbow-gnostic
--there are any credential-enforcement Trolls beneath the nonexistent bridge-space.)

er, Arf.. Arf..
