Rabbi Shimon Bar Yochai

“ The heart discerns, the heart knows, the heart sees; the heart is the Shekhina, which only picks up clear blood, which is the offering of clean prayer without sins and without waste, and delivers to her Husband the finest (Shufra) of everything.
לֵב מֵבִין, לֵב יוֹדֵעַ, לֵב רוֹאֶה, לֵב אִיהוּ שְׁכִינְתָּא, דְלָא נַטְלָא אֶלָּא דְמָא צַח, דְּאִיהִי קָרְבָּנָא דִצְלוֹתָא נְקִיָּה בְּלָא חוֹבִין וּבְלָא פְּסוֹלֶת, וּקְרִיבַת לְגַבֵּי בַּעִִלָהּ שׁוּפְרָא דְכֹלָּא. But the YWTRT HKBD only gives her husband leftovers and waste. And who is her husband? (spleen) (o.v. liver) - "other god". ”

“ After doing promiscuity with all of them, she gives surplus extra to her husband. Of this it's said (Song 4:26) , "On account of a promiscuous woman, down to a loaf of bread," since she is warmed up by the liver, and spleen (daf 49b) is the laughter of the fool, and of this it's said, "If you see a wicked man on whom the hour is cheering, do not scold him," since it's lower Sheol, of which it says, "who swallows up the one more righteous than him." But a total Tzaddik he does not swallow. The liver gets angry and kills. ”

“ Nefesh-Ruach, as Nefesh is the wick (o.v. since she is partnered with the body) , Ruach is the olive, Neshama - "the Ner of Hashem is the Neshama of man" (Prov. 20:27) , (Adam is the light of the lamp, in him shines the written Torah, and the Neshama which is Ner, in her shines Miswa. But when light and lamp doesn't shine in her it's said of the Neshama (Song 1:6) , "Don't look at me, for I'm blacked out," and it's said of man (Isa. 50:3) , "I'll don dark skies") . And what's Ne"R? Nefesh-Ruach, N' Nefesh R' Ruach, corresponding to these three rings ”
