Sources – Chapter C – Part 5 – On Time and Space

…it seems to be a span of seventy years, yet to the greater intellect it is only a quarter of an hour. And so on, higher and higher: for an intellect that is higher still, even that time which exists in the intellect higher than ours is not reckoned there, in the yet higher intellect, as anything but a little time, and very much less. And so on, higher and higher, until there is an intellect so high that there all of time is not reckoned at all; for because of the very great intellect, all of time is utterly nothing and naught. Just as for us the seventy years that pass in a dream are in truth only a quarter of an hour, as above, so too there is intellect above intellect, until time is entirely nullified.

Therefore the Messiah, over whom has passed all that has passed since the day the world was created, and who has suffered what he has suffered – after all this, at the end, Hashem, blessed be He, will say to him: "You are My son; today I have begotten you" (Psalms 2). At first glance this is very puzzling and wondrous. But all this is because of the very great essence of the Messiah's intellect, according to the greatness of the level he will then attain, and because of the extraordinary essential loftiness of his intellect, which will then grow very, very great. Therefore all the time that has passed over him from the day the world was created until that time will be utterly nothing and naught, and it will be truly as though he were born today, for all of time will be nullified in his intellect, which will be very great. And therefore Hashem, blessed be He, will say to him: "Today I have begotten you" – literally "today," for all the time that has passed is entirely nothing and naught, as above.

And so we see with space as well: a strong person can cross a great distance in a short time. It turns out that for him that whole space is small, while for the weak that space is reckoned as great, and they need to walk a long time until they cross it. So too, higher and higher: the greater the power, the smaller space becomes for it; and so on, higher and higher, until space is entirely nullified. Only that with our intellect it is impossible to understand all this – just as in a dream it is impossible to understand the truth, that all the time that seems [to pass] in the dream is in truth nothing; so too it is impossible for us to understand that all our time is nothing above, in the higher intellect, as above.
