When rearranging the letters of שלח, we arrive at the word חלש. Indeed, the spies showed weakness by not wanting to enter the land in order to use physicality towards a spiritual end.
Luckily for us, Shavuos is every day. The Zohar proclaims that the Torah is given anew every day. This conforms with the Mishna in Pirkei Avot that says, “A daily voice from Har Sinai proclaims, ‘Woe to the disgrace of Torah.’”
My late relative, Rav Avrohom Genechovsky zt”l, provided me with an insight that sheds light on nature and in turn the Volcano in Hawaii that has been erupting.
He said the outside of the earth is mainly covered in water, the center of earth is energized by fire and the inner core is rock-solid. Based on this he said that our behavior should be modeled after the makeup of the world. On the outside we should be malleable and flexible with our neighbors like water, our center should be guided by fire, namely the Torah, and our inner core should be rock-solid in our beliefs like the inner core of earth.
The Volcano might make for exciting news, but it also exhibits the pouring out of fire from the center of earth that symbolizes what our center should be filled with on a daily basis, the fire of Torah.
