Description

P. 278 in the commentary (7th perek). The word 'mutar' means released from imprisonment from the Other Side, untied. A thought of Hashem can draw permitted food back to the nefesh Elokis. The impression that the food makes on the body can only be cleansed through the Chibut HaKever (the beating in the grave). In intimacy, if the intentions have taiva in them, the life force also goes temporarily into the Other Side, but can be retrieved through learning or doing mitzvos. The sparks of kedusha (holiness) get lost, almost forever, through eating unkosher food, or eating kosher food at a forbidden time, like Yom Kippur.
