What does Professor Henry Jones Sr mean of "illumination"?

@TheOneyouwerewarnedabout Illumination is truth, you mean?

i havnt seen it in a long time.. but by memory.. elsa wanted to take the grail.
henry realises after all them years of looking for it. that it was never meant to be found..

hope that helps..

@TheOneyouwerewarnedabout I see. It probably was never meant to be taken from the crusade, especially out past the Great Seal, as according to the Knight, one of the three brothers who were assigned to protect, "The Grail cannot pass the beyond the Great Seal as it the boundary and the price of immortality."

But at least while searching for it, Elsa kept the real one away from Walter Donovan, the main antagonist, and thereby kept it out of the reach of the Nazis also. Indy and Henry at least let it go as it was at least kept out of the hands of the Nazis. If the Nazis did get it, the armies of darkness and evil would march all over the face of the Earth and the whole world would be destroyed. So at least they did keep it out of the hands of the Nazis, and that, in Henry's case, would be the "Illumination". Makes total sense.

@SamHarris i dont think donovan had any intention of handing it over to the nazis either.. he like elsa wanted it for himself..

@TheOneyouwerewarnedabout But he did have an alliance with them, and thereby was actually part of them, what with selling out his country, and his own soul to the slime of humanity, as Henry pointed out. But at least Elsa purposely picked the wrong grail, which then actually aged him so rapidly and thereby causing him to decay and turn to ashes and dust, and his pin with the Nazis, indicating his alliance with those scumbags.

Still, the Joneses kept it out of the hands of those scumbags, especially Donovan, whether it was meant to be found and taken or not. But whether they let the grail lay in that chasm or not, it was kept out of the hands of those scumbags.

@SamHarris he needed money. trucks and protection to get to where he wanted to be.. he exploited the nazis..

@TheOneyouwerewarnedabout Right. Still, he had an alliance with those guys.

@TheOneyouwerewarnedabout So we know in illumination, he meant that the Grail was never meant to be found; yet it still got kept out of the hands of Donovan and the Nazis.

But what what he said in the beginning? "May he who illuminated this... illuminated me." What's that one mean?
