Oh, dear... a neo
grok : from the infamous SF novel Stranger in a Strange Land by the man some still consider to be the Grand Master (and he certainly was, for about 2 decades), Robert A Heinlein.
No direct translation is given from the Martian, but the essential meaning is "to comprehend fully, after contemplation".
By using it, RNE was referring to yet another aspect of the same novel: the concept that all of us, both individually and collectively, are God. ("Thou art God" is a direct quote.)
