(11) For the Shechina (divine presence) dwells within them just as it dwelled in the Temple. Due to this, the food they eat is like a sacrifice offered upon the fire of the altar, for certainly it was a great elevation for those things to be offered on the altar, since they were offered before the Shechina.
(12) The elevation was to such an extent that its kind, all over the world, was blessed, as our sages stated in a Midrash. So too, the food and drink which the holy man eats elevates that food or drink as if it had actually been offered on the altar. This is similar to what our sages, of blessed memory, said: "one who brings a gift to a Torah scholar is as if he had offered first-fruits (Bikurim)" (Ketuvot 105b), and "[if a man wishes to offer a wine libation upon the altar], let him fill the throat of the Torah scholars with wine" (Yomah 71a).
(13) This does not mean that Torah scholars were craving for food and drink, G-d forbid, that one fills their throats like one stuffs a glutton. Rather, the matter is according to the intent I explained. That Torah scholars who are holy in their ways and in all their deeds are actually just like the temple and the altar, for the Shechina (divine presence) literally dwells upon them as it did in the temple. Thus, what is offered to them is as offered on the altar, and the filling of their throat is as the filling of the basins.
(15) The general principle of the matter: Holiness consists of one's clinging so much to his G-d that for any action he does, he will not separate nor budge from G-d, blessed be He, so that the physical things he uses will attain greater elevation than that which he diminishes in his clinging and level due to his using physical things.
