Some folks, say those afflicted with techie genes, like to call 'it' 'other dimensions'; that way a one can imagine ~ "we'll solve it Real Soon Now.."
Most call it 'higher levels of consciousness'. Possibly attainable with certain sorts of efforts -??- but not transmissible to another homo-sap, second-hand (gotta Love Cosmic Humor, if'n ya wanna chat w/ Godheads.)
We live by and kill for metaphors every day.
