The vegetation that represents new creation is the aspect of light ‘sprout’ from darkness. The Left-side comes to be among the vegetation to draw from their light and grow.
“וַיֹּאמֶר אֱלֹהִים, יְהִי מְאֹרֹת בִּרְקִיעַ הַשָּׁמַיִם, לְהַבְדִּיל, בֵּין הַיּוֹם וּבֵין הַלָּיְלָה; וְהָיוּ לְאֹתֹת וּלְמוֹעֲדִים, וּלְיָמִים וְשָׁנִים”
“Then God said, “Let there be lights in the expanse of the heavens to separate the day from the night, and let them be for signs and for seasons and for days and years;”
The word for ‘lights’ ‘מְאֹרֹת’ is missing the letter Vav ו that represents Zeir Anpin and central column. Zeir Anpin delivers the light to Malchut and the missing Vav ו means that Malchut doesn’t have light of her own.
The word ‘מְאֹרֹת’ also means ‘curses’. The root is אר in the middle and the first and last letters spell ‘מת’, which means ‘dead’. When work to unify the two sides in the central column, Zeir Anpin,
‘מְאֹורֹת’ we reveal the light ‘אור’ inside the ‘dead’ vessel and bring life into it.
The word ‘מְאֹרֹת’ also refers to the cursed Snake that doesn’t have light of his own. He always after our ‘heel’ to take our light.
This process of Creation gave us advantage over the negative side because we can earn the light (Genesis 3:19) while the Snake depends on our mistakes for high level nourishments.
