‘?? ??? ???? ?? ???? ???
That is the way of Torah (eat bread and salt and sleep on the ground).
Sailors (?????) have the root ???, which means salt. The job of sailors it to row with the oars the salt in the water that holds the ship back( Olam Habah) and mix it with the water (Olam Hazeh).
Salt is related to the Bris Hamelech (the ‘Covenant of the Salt’) which relates to the Olam Haboh.
The job of a Torah Scholar is to Metaken the Olam Hazeh, e.g. by eating and making a Brocha (Olam Hazeh), so he can merit Olam Haboh.
