After Joseph interpreted Pharaoh’s dream, he was appointed to control over all Egypt. Obviously, God brought him to that position and the Zohar explains that the reasons for Joseph merits concealed in the Torah verses.
For keeping his mouth pure Joseph could command others.
“אַתָּה תִּהְיֶה עַל בֵּיתִי וְעַל פִּיךָ יִשַּׁק כָּל עַמִּי רַק הַכִּסֵּא אֶגְדַּל מִמֶּךָּ”
“”You shall be over my house, and according to your command all my people shall do homage; only in the throne I will be greater than you.””
He was called wise (Genesis 41:39) because his mind had positive thoughts. His hand, his body and neck were all pure and worthy to receive the honor of a king.
“וַיָּסַר פַּרְעֹה אֶת טַבַּעְתּוֹ מֵעַל יָדוֹ וַיִּתֵּן אֹתָהּ עַל יַד יוֹסֵף וַיַּלְבֵּשׁ אֹתוֹ בִּגְדֵי שֵׁשׁ וַיָּשֶׂם רְבִד הַזָּהָב עַל צַוָּארוֹ”
“Then Pharaoh took his signet ring from his hand and put it on Joseph’s hand, and clothed him in garments of fine linen and put a gold chain about his neck.”
“וְיוֹסֵף בֶּן שְׁלֹשִׁים שָׁנָה בְּעָמְדוֹ לִפְנֵי פַּרְעֹה מֶלֶךְ מִצְרָיִם וַיֵּצֵא יוֹסֵף מִלִּפְנֵי פַרְעֹה וַיַּעְבֹר בְּכָל אֶרֶץ מִצְרָיִם”
“Now Joseph was thirty years old when he stood before Pharaoh, king of Egypt. And Joseph went out from the presence of Pharaoh and went through all the land of Egypt.”
Joseph ‘went through all the land of Egypt’ in order to have the control over the collection and storage of the cereal grains. Rabbi Elazar explains that the storage was local so the grains won’t rot. Rabbi Ashlag adds that the natural energy of the area protects its crops.
Our body represents the Tree of Life (Deuteronomy 20:19, “Man is like a Tree (of Life) in the field (Malchut)”, Genesis 1:27 “In the image of God he created him (Man, Adam)”= Tree of Life). When the body is pure then we can channel the light that flows through the Tree of Life. Watch video below about Tikun Hanefesh and our body as image of the Tree of Life.
Rabbi Shimon was in a cave for 13 years and when he came out his physical body was weak,wounded and sore but his spiritual body was pure to a point that he could command heaven and earth like a king.
One more important lesson is the effect of the energy that the local environment on us. Joseph chose to store the crops locally for a good reason. We see people in different regions in the world, share similar body features, like skin color, eyes, nose, height etc. What less obvious is that the body is also affected internally by the food we eat. It’s always better to eat locally grown food and especially seasonal produce. They grow under the the same energy of the season that we live in and can bring positive effect on us. It’s even better to eat food made at home rather than preserved food made in far away countries. Their energy may not match ours and we should avoid that. People that migrate from one region of the world to another should pay close attention to their food and allow gradual adjustments to avoid weight change and shift in body energy that could bring sickness and diseases.
