The 12 precious stones are the 12 oxen under the sea that was built by King Solomon. When the Holy Tabernacle was completed, the twelve heads of the tribes brought offerings on counts of 12 to connect to the light that feed the Holy Tabernacle.
“כָּל הַבָּקָר לָעֹלָה שְׁנֵים עָשָׂר פָּרִים אֵילִם שְׁנֵים עָשָׂר כְּבָשִׂים בְּנֵי שָׁנָה שְׁנֵים עָשָׂר וּמִנְחָתָם וּשְׂעִירֵי עִזִּים שְׁנֵים עָשָׂר לְחַטָּאת”
“all the oxen for the burnt offering twelve bulls, all the rams twelve, the male lambs one year old with their grain offering twelve, and the male goats for a sin offering twelve;”
Zeir Anpin is the central column and its 6 sefirot make a vessel with 12 ‘connectors’ that receive the Light from the upper three sefirot. With proper connection we can draw this light to Malchut.
Rabbi Shimon quotes Rabbi Chizkiya saying that when God created Adam, he used dust of the Holy Temple in Malchut to form his body. From the Holy Temple at the spiritual level above that is Binah he gave him the soul.
During his creation, Adam was connected to the elements of Fire, Air and water of the lower level. To make Adam complete he received the soul from the upper level with the aspects of Fire, Air and Water.
“אַשְׁרֵי אָדָם לֹא יַחְשֹׁב יְהוָה לוֹ עָוֹן וְאֵין בְּרוּחוֹ רְמִיָּה.”
“How blessed is the man to whom YHVH does not impute iniquity, And in whose spirit there is no deceit!”
The Zohar explains that a man is considered without inequity when his soul is from Binah.
The four elements are the foundation of the material world with similar aspects in the upper spiritual world. We are born in one of the 12 months that is divided into four categories of Fire, Air, Water and Earth. We can achieve purity and high level of the soul when we overcome the negative aspects of the lower four and connect to the pure one above.
Negative – Laziness, sadness
Positive – Proactive, happiness, appreciation
Negative: Evil Speech, Flattery, Gossip, lies
Positive: Study Holy Scriptures, teach, positive speaking
Negative: Pride, anger, rigour
Positive: Humility, reduce ego
Negative: Desires for pleasures, jealousy, envy
Positive: Support others, be happy with what you have
Negative thoughts should be controlled, no pessimism, no sexual fantasies.
Work on bringing the Light and the spiritual aspect in every action. Desire to purify and expand the soul with studies and spiritual connections.
