It is a day before Rosh Chodesh, called by some Yom Kippur Katan (Minor Yom Kippur). This is a day of fasting and repentance as Yom Kippur is, but it is not Jewish law and by my knowledge it is not observed. The custom origins from the Safed Kabbalists. Their view is that originally there was harmony between sun (seen as Tifaret) and moon (seen as Malkut), the Shekhiah. These lights were of even size and strength. But in time the moon and sun were separated, caused by Israel’s sinfulness. When the Messiah comes the harmony between the sun and the moon will be restored. The new moon each month is welcomed as evidence of future redemption of the Shekhinah, but the day before is a day of prayer and repentance for the sins committed during the previous month in order hasten the coming of the Messiah and the redemption of the Shekhinah.
On this Yom Kippur Katan my question is: What is my main sin in the previous month? I received Five of Swords from the Gilded Tarot, and it cost me all day to figure out why.
Here comes my sin. During the holiday I tried faithfully to do all my duties, but while doing them I was angry, hence the swords under my arm and the red clouds near my head. I should have talked about it much sooner. That would have helped a lot. Thus, my sin is that I kept my anger while doing my job.
My prayer, Oh God, hear my voice in the night, forgive me my wrongdoings towards others, you and towards myself My wish is that I had done otherwise. Oh God, I know you hear my voice and I know you will answer me.
