Chapter 10 · The Third Pentad: Wheat's Autumn Arrives—The Temporal Mystery That Ripeness Itself Is "Autumn"

I. "Wheat's Autumn Arrives": The Phenological Reality of the Third Pentad

The third pentad of Xiaoman is "wheat's autumn arrives" (麦秋至).

At first glance, the three characters "wheat's autumn arrives" seem puzzling—Xiaoman is plainly early summer (the fourth lunar month), so how could there be "autumn"$20 What, exactly, is this "wheat's autumn"$21

Commentators through the ages have offered a precise explanation. The so-called "wheat's autumn" does not refer to the autumn season at all, but to "the season when the wheat ripens." Wu Cheng of the Yuan dynasty, in the Collected Explanations of the Seventy-Two Pentads of the Monthly Ordinances, explains: "Wheat's autumn arrives. 'Autumn' is the period when the hundred grains ripen. Though this is summer in terms of the season overall, for the wheat it is its autumn—hence it is called 'wheat's autumn'" (麦秋至。秋者，百谷成熟之期。此于时虽夏，于麦则秋，故云麦秋也). "Autumn" is the period when the hundred grains ripen. Although this season is, overall, summer, for the wheat specifically it is its "autumn" (its period of ripening)—hence the name "wheat's autumn."

The truth is now clear: "wheat's autumn arrives" means that, by the end of Xiaoman, the wheat is about to ripen, and the wheat's own "autumn of harvest" has arrived.

Yet hidden behind this explanation lies a mystery capable of shaking our very conception of time—it turns out that the character "autumn" (秋), in its original meaning, did not refer to a season at all, but to "ripening"!

II. The Original Meaning of "Autumn": Ripening, Not a Season

This is the greatest insight offered by this pentad, "wheat's autumn arrives"—it reveals the original meaning of the character "autumn."

The "autumn" we understand today is the third of the four seasons of the year, a concept of time. But "wheat's autumn arrives" tells us: to our ancestors, "autumn" was, first and foremost, a concept of "ripening," not a concept of "season."

Why does "autumn" carry this original meaning of "ripening"$22 Etymologically, the character qiu (秋, "autumn") is composed of "grain" (禾) and "fire" (火) (ancient graphic forms are sometimes said to derive from "tortoise" or "cricket," accounts vary, but "grain" is undoubtedly its core semantic component); its original meaning is closely bound up with the ripening of grain crops. When grain ripens, its color turns golden, like fire—hence qiu is composed of "grain" and "fire." Within the year, grain crops (millet and the like, the staple grains) ripen in the third season, and so this original meaning of "grain ripening" was extended and fixed as the seasonal meaning of "the third season."

In other words, the logical chain behind "autumn" runs: grain ripening (original meaning) → the season in which grain ripens (extended meaning) → the third season (fixed seasonal meaning). Today we know only the seasonal meaning of "autumn," and have forgotten that its original meaning was "ripening." This pentad, "wheat's autumn arrives," precisely preserves that most primal meaning of "autumn" as "ripening"—the ripening of the wheat is the wheat's own "autumn," even though the season, plainly, is summer.

What an astonishing discovery this is! A seemingly ordinary phenological name, "wheat's autumn arrives," has, it turns out, preserved for us the most ancient original meaning of the character "autumn," allowing us a glimpse into our ancestors' primal way of thinking when they coined characters—"naming the sequence of time after ripening."

III. The Relativity of Time: Every Crop Has Its Own "Autumn"

"Wheat's autumn arrives" also reveals a profound philosophical proposition—the relativity of time.

Since the original meaning of "autumn" is "ripening," every crop has its own "autumn" (its period of ripening). The wheat's "autumn" falls in early summer (around Xiaoman); the rice's "autumn" falls in mid-autumn; melons and fruits each have their own "autumn." "Autumn" is not an absolute time fixed to a particular season, but a differently timed "moment of ripening," relative to the maturation rhythm of each individual form of life.

What a dialectically wise conception of time this is! In the view of our ancestors, time was not a homogeneously flowing "absolute time" that treats all things equally, but a "relative time" profoundly bound to the growth rhythm of each individual life. The very same physical moment (Xiaoman) is "autumn" (ripening) for the wheat, yet "spring" (sowing) for the rice; it is "death" for the mi grass, yet "flourishing" (xiu) for the bitter herb. All things have their own respective times, their own respective "springs, summers, autumns, and winters," which need not necessarily align with the astronomical four seasons.

This relative conception of time, in which "all things have their own respective times," resonates deeply with Master Zhuang's wisdom of "the equality of things." The "Free and Easy Wandering" (Xiaoyao You) chapter of the Zhuangzi states: "Small knowledge does not reach to great knowledge; a short lifespan does not reach to a long one. How do we know this is so$23 The morning mushroom does not know the alternation of dusk and dawn; the cicada that lives but a season does not know the alternation of spring and autumn—these are short lifespans. South of the state of Chu there is a creature called Mingling, for which five hundred years make one spring, and five hundred years make one autumn; and in remotest antiquity there was a great tree called Chun, for which eight thousand years made one spring, and eight thousand years made one autumn" (小知不及大知，小年不及大年。奚以知其然也？朝菌不知晦朔，蟪蛄不知春秋，此小年也。楚之南有冥灵者，以五百岁为春，五百岁为秋；上古有大椿者，以八千岁为春，八千岁为秋).

The mushroom that is born in the morning and dies by evening knows nothing of the passing of a month; the cicada that lives through spring and dies in summer, or lives through summer and dies in autumn, knows nothing of the passing of a year's spring and autumn—these are "short lifespans." Yet Mingling takes five hundred years as one spring, five hundred years as one autumn; and the great tree Chun takes eight thousand years as one spring, eight thousand years as one autumn—these are "long lifespans." The very same "spring and autumn," for the morning mushroom, the short-lived cicada, Mingling, and the great tree Chun, turns out to differ as widely as Heaven from Earth!

This passage of Master Zhuang's, and the "relativity of time" revealed by "wheat's autumn arrives," are one and the same profound insight. "Autumn" (ripening) differs for the wheat, for the rice, for Mingling, for the great tree Chun. Time is not absolute, but relative to the rhythm of each individual life. This seemingly ordinary pentad, "wheat's autumn arrives," conceals within it so profound a philosophy of time—it reminds us: do not measure the "time" of all things by one's own "time" alone; all things have their own ripening, their own "autumn."

IV. "Wheat's Autumn" and "Xiaoman": The Resonance of Ripening Approaching but Not Yet Arrived

"Wheat's autumn arrives," as the final pentad of Xiaoman, forms an exquisite resonance with the central theme of "Xiaoman" itself.

Note that this third pentad says "wheat's autumn arrives" (麦秋至)—the wheat's autumn of ripening is about to arrive—rather than "the wheat has ripened" or "the wheat may be harvested." During the Xiaoman stage, the wheat is "approaching ripeness but not yet ripe"—it is filling out, becoming plump (small fullness), and about to ripen (wheat's autumn approaching), but has not yet reached the true state of "great fullness" (fully ripe, ready for harvest). The wheat's true ripening and readiness for harvest must wait for the next solar term, Mangzhong.

This, too, is a state of "approaching but not yet arrived"! Wheat's autumn "arrives" (approaches), but the wheat has "not yet ripened" (not yet complete). Xiaoman pauses precisely at this threshold of "wheat's autumn approaching, but the wheat not yet fully ripe"—brimming with the hope of an imminent harvest, yet still restrained, unwilling to declare completeness.

From this we can see that Xiaoman's three pentads—"the bitter herbs flourish" (sweetness gestating within bitterness), "the mi grass dies" (loss lurking within fullness), and "wheat's autumn arrives" (approaching ripeness but not yet ripe)—build upon one another in successive layers, each from a different angle jointly setting off the core mood of "Xiaoman": approaching fullness but not yet full, leaving room to spare. The bitterness of the bitter herb is the tempering that precedes abundance; the death of the mi grass is the warning within fullness; the arrival of wheat's autumn is the restraint before ripening. Taken together, the three pentads form a complete philosophical portrait of "Xiaoman."

V. What "Wheat's Autumn Arrives" Reveals About the Urgency and Composure of Farm Work

"Wheat's autumn arrives" also leads us to the most important human affair of the Xiaoman season—preparation for the summer harvest.

"Wheat's autumn arrives" means that the summer harvest (reaping the wheat) is now imminent. A farming proverb says, "If Xiaoman is not full, the wheat faces a risk" (小满不满，麦有一险), and another says, "By Xiaoman, the wheat turns golden day and night" (麦到小满日夜黄). During Xiaoman, the wheat ripens to a golden color a little more each day, and the farmer's heart grows a little more anxious with each passing day as well—looking forward to the harvest, yet also worrying whether, at this threshold of "approaching ripeness but not yet ripe," wind, rain, or hail ("the wheat faces a risk") might strike, destroying a harvest so nearly within reach.

This state of mind—tension and composure coexisting amid a harvest "approaching but not yet gathered"—is precisely the human portrait of the spirit of "Xiaoman." On the one hand, the harvest is in sight, brimming with hope (fullness); on the other, it is not yet in hand, and one dares not let down one's guard (not yet full). The farmer's complex mood at Xiaoman—filled with anticipation, yet treading as if on thin ice—is the truest lived experience of the philosophy of "Xiaoman," of "approaching fullness but not yet full." Our ancestors crystallized this urgency and composure of "approaching ripeness but not yet ripe" into the pentad "wheat's autumn arrives," and likewise crystallized it into the very naming of "Xiaoman" as a whole.
