Musar for Daniel 10:6

I once read an explanation of this: When a man commits adultery a malignant spirit is created in the form of the woman with whom he strayed. Then, when his time comes to leave this world, she wraps herself around him and drags him down to Gehinnom. It seems to me that this is what the Sages were alluding to when they said (Sanhedrin 100a), “In the future the Holy One Blessed is He will bestow upon every righteous person three hundred and ten worlds. As it is written, ‘To cause those who love Me to inherit substance (yeish, the numerical value of which is 310)’ (Mishlei 8:21).” I have heard this passage explained as follows: As we have already mentioned, when a man does a single mitzvah a single angel is created. The Sages tell us (Chullin 91b) that each angel is two thousand parsaos across (1 parsah = 2.80 miles.), as it is written, “And its body was like [the Sea of] Tarsus” (Daniel 10:6). According to tradition this sea was two thousand parsaos wide. Now altogether there are 613 Torah precepts and seven rabbinical enactments, totaling 620, the numerical value of the word keser — “crown.” Therefore, when the Jewish people keep the entire Torah, including the rabbinical injunctions, they acquire 620 angels.
