Perkie avot, perek daled, mishna yud alef:
“One who does a mitzvah, a malach will defend him” a sanegor echad- defending angel. “And one who does an aveira will get a malach against him” a kategor echad- prosecuting angel. Q: what’s the mishna trying to tell us? Are we here to find ourselves only one mitzvah? A: even ONE mitzvah is worthwhile.
“If there is one defending angel against one thousand prosecuting angels, the defending angel will speak about the good of a person and he will find favor in the eyes of Hashem and that person will be redeemed from gehenam” that’s the power of one mitzvah.
In order to get rid of the prosecuting angel a person has to do 1.Sincere teshuva 2. Ma’asim tovim.
Hope this made sense lol and hope everyone enjoyed!
