Tikkun 21 – 28
The wisest of all man, King Solomon, tells us in his coded teaching in Proverb 19:2 “גַּם בְּלֹא-דַעַת נֶפֶשׁ לֹא-טוֹב”
“Also, the soul without knowledge is not good”
The deeper meaning of this verse is that a proper connection draws the light to the soul and body.
Knowledge is the Sefira of Da’at. It is revealed only when there is a connection between Chokmah (Wisdom) and Binah (understanding), which are the Supernal Father and Supernal Mother.
Look at Da’at as the extension of the middle brain. It goes down from the head through the spine (central column) to the body and gives it life and strength.
It is known that the body of great tzadikim do not fall into the laws of entropy. Even after death their bodies preserve themselves in a life like state. The light that is drawn down by proper connections and positive actions affect the body. The highest level is when the whole body is corrected by all aspects of positivity and it keeps an inseparable state with the light, no physical law can affect it.
That is why Tzaddikim are called ‘living’ in their death.
