Keep the month of aviv (spring), and observe [in it] a Passover
I will sow the house of Israel with the seed
of man and the seed of beast
The Jewish calendar is closely attuned to the agricultural
seasons. Passover must coincide with the season of aviv,
which is broadly defined as “spring” but specifically means
the season of the ripening of barley. Shavuot is called “the
reaping festival” and coincides with the reaping of the staple
crop, wheat. Sukkot is the “harvest festival,” celebrated
as the grain, which has been drying in the field all summer,
is brought into storage. And then there is Tu B'Shvat, the
“New Year for Trees,” observed as the first tree-blossoms
emerge from the winter slumber. Indeed, our calendar goes
to great lengths to reconcile its lunar-based months with
the solar-based seasons.
Our forefathers, celebrating these festivals in the Holy
Land thirty centuries ago, were primarily an agrarian people.
Still, even then there was Levy, the tribe of priests, Shimon,
a tribe of schoolteachers, the scholars of Issachar, and the
seafaring merchants of Zebulun. Today, a very small percentage
of us work the land. But Torah, G-d's blueprint for creation,
obviously transcends differences of time and cultural circumstance
and is deeply relevant to all generations and all societies
of history. So what does all this mean to those of us who
never planted a seed or gathered a harvest?
But the very experience of life is agrarian. The soul's descent
into physical life, like the planting of a seed, is an investment---a
precarious investment at that, given the fact that one's capital
erodes significantly before turning a profit. The farmer who
sows his field knows that he is taking perfectly good grain--grain
with which he could feed his family--and casting it into the
soil, where it will soon disintegrate. But he also knows that
the rotting seed will stimulate the earth to yield many times
the grain he “squandered.”
The soul, too, is buried in earth---cast into a body of clay
with material drives and desires. It is worse for the wear:
its spiritual senses are dulled, its moral compass compromised.
But the soul's interment in earth and earthiness stimulates
it, and the body and the physical environment in which it
was invested, to yield their tremendous potential---a potential
far greater than the soul itself could achieve.
The human “farm” includes many and varied crops. On Passover
we celebrate the ripening of barley, a grain that serves primarily
as animal feed. In human terms, this represents the development
of the animalistic nature with which the soul has been saddled
upon its descent into the physical state, but whose passion
and intensity surpass anything the spiritual soul can muster
for its own spiritual ideals. Properly cultivated and directed,
the beast in man thus proves a priceless resource in the soul's
quest to deepen and intensify its bond with its Creator.
On Shavout, wheat, the staple of the human diet, is harvested.
This represents the fruition of another dimension to the sowing
of the soul: the development of the “human” element in man,
the soul's own spiritual potential. The challenge of converting
the earth's resources into nourishing grain provokes deep-seated
powers of the soul which it would otherwise never have realized,
just as a kernel of grain would never have been revealed to
be more than a single kernel of grain had it not been sown
in the earth.
And so it is with the other agricultural events on the Jewish
calendar, such as the “internalization” of the harvest on
Sukkot, or the element of “delight” in life represented by
Tu B'Shvat's fruit blossoms: each embodies another aspect
of the soul's journey as seed, tender shoot and glorious harvest.
