The Torah, “Leviticus” 25:19 – 25:21: And the land will then yield its fruit and you will eat to satiety, and live upon it securely. And if you should say, “What will we eat in the seventh year? We will not sow, and we will not gather in our produce!” [Know then, that] I will command My blessing for you in the sixth year, and it will yield produce for three years.
If I observe and keep the spiritual laws, I have no problems and am under the protection of nature. But when I delve into my ego and begin to operate on my own, I cannot count on harvesting the crops for the three years to come.
Can you imagine what would happen if I have a poor crop in the sixth year? What will I eat during the three years that follow? Nothing. In ancient times, people were dependent totally on what the land gave them.
Question: What does this symbolize with regard to our internal state?
Answer: I correct my desires and fill the six Sefirot: Hesed, Gevura, Tifferet, Netzach, Hod, and Yesod. They all concentrate and accumulate in the Sefira of Yesod, which moves on to Malchut and raises Malchut all the way to Bina. Therefore, I have no problem existing in Malchut. Malchut is the vessel from which I am nourished for three years.
