Yom Kipur

Yom Kipur ("יום כיפור") comes ten days after Rosh Hashana & it's known as the day of atonement.
If Rosh Hashana symbolizes a new beginnings (the first Hebrew letter Resh represents Mars,as shown in the previous post), Yom Kipur symbolizes the release from the Karma of the past.
Yom Kipur starts with the letter Kaf ("כ") which traditionally represents the sun.
The sun represents the inner self in astrology so the procedure of atonement must come from the deepest parts of the soul.
More than that, the shape of the letter Kaf traditionally looks like a bent stick which means that only modesty ("bent personality") can bind you to the sun's essence (the inner self).
In addition, the letter Kaf composes the word Kol ("כל") which means "everything".
The letter lamed ("ל") that comes after the letter Kaf is traditionally the letter of learning so learning the essence of the letter Kaf can develop the ability to contain everything(part of Pluto's essence).
Indeed, in the procedure of atonement you must contain the whole you.
You must have Pluto's essence, you have to be deep & thorough like it in order to contain the whole you.
Pluto is known as a Karmic planet so you have to have its essence in order to deal with your Karma & to release yourself of it.
The release from the Karma actualizes by the regeneration of the same Pluto.
The other letters Pe ("פ") & Resh ("ר") symbolizes the new beginnings(represented by Mars) that comes after the release from the Karma.
the letter Resh is more opened to the left than the letter Pe.
The fact that the less opened Pe comes before the more opened emphasize the gradation of this process (the hatch of the new beginnings opens itself gradually).
The process of atonement is gradual but not only because you must have Pluto's essence (depth & thoroughness in order to contain the whole you, as said above) but also because you have to develop Saturn's essence & to be responsible to who you're & what you do (it's known that Saturn develops everything gradually).
Saturn is also a Karmic planet & hence also emphasize the Karmic side of Yom Kipur.
Neptune which is also a Karmic planet takes place in Yom Kipur in general.
It helps you bind all the parts of your personality(which Pluto helps you to contain) & eventually helps you unite with the ultimate power of altruism which rules the whole universe (as much as a pride brings the egoism, the modesty (caused by this "bent personality") brings the alteruism & that's way Neptune takes place in this day in general).
Uranus also takes place in this day by making Yom Kipur a unique day which breaks the routine of fixed eating times & eventually helps to break your Karma in order to let your authenticity grow.
