Rabbi Chiya responded to Rabbi Chanina, “How do you dare argue with me? For I make sure the Torah is not forgotten from Yisrael to begin with. What do I do? I go and sow flax; then I weave nets from the flax. I trap deer with them, and I feed their meat to orphans. Then I prepare scrolls of parchment (with their skins),
and I write the five chumashim (of the Torah on them). I go
to the village (where there is no one to teach the children), I
teach five children the five chumashim (each one a different chumash), and I teach another six children the six orders of the
Mishnah (by heart—each child a different order). Then
I say to them, ‘Until I come back, teach each other Torah and teach each other Mishnah.’ Thus, I ensure that the Torah will never be forgotten from Yisrael.”  

 Taking into account all that we have discussed, we learn a fundamental principle. The Bet HaMikdash above in the heavens represents the letters י”ה , which stand for ;י’שמחו ה’שמים whereas the Bet HaMikdash down below on earth represents the letters ו”ה
, which stand for ו’תגל ה’ארץ .
