📖 Origin
The character 芥 is a phono-semantic compound combining 艸 (grass), meaning plant, with the phonetic element 介 (gae). 艸 conveys a plant-related meaning, while 介 itself carries the senses of "to be wedged in," "boundary," or "small." It originally referred to mustard or small plants, and from early times was used to mean a small plant. The form of the character has changed little, continuing to the present day.
🔍 Structure
艸 (grass) + 介 (to be wedged) = 芥 (mustard)
This character was formed by combining the 艸 radical, meaning plant, with 介, which represents the sound. 介 also carries the senses of "small" or "wedged in," which suits well the minute existences that 芥 denotes — small plants, mustard seeds, or specks of dust. Characters of similar construction that use 介 as a phonetic element include 界 (boundary) and 街 (street).
🏛 Philosophy
Buddhism
芥 is frequently used in Buddhism to mean "mustard seed," and is especially well known through the concept 芥子須彌 (gaeja-sumi). This means "within an utterly tiny mustard seed the vast Mount Sumeru is contained," a metaphor for how boundless truth dwells within what is small. It is an important teaching that brings one to realize the truth that all phenomena are originally empty (空) and that there is no discrimination between great and small.
Eastern Philosophy
The "smallness" and "minuteness" symbolized by 芥 connect, in Eastern philosophy, with the idea that "the macrocosm exists within the microcosm." It emphasizes that within seemingly insignificant existences lie genuine value and infinite possibility, awakening the humble attitude — like "a mountain made of gathered specks of dust" — that does not overlook the importance of small things. This becomes the starting point for a profound insight into how we view things and phenomena.

Buddhist Maxim

Zhuangzi, "Free and Easy Wandering" (逍遙遊)
故夫知效一官, 行比一鄉, 德合一君, 而徵一國者, 其自視也, 亦若此矣 ... 未數數然也. 雖然, 猶有未樹也. 夫列子御風而行, 泠然善也, 旬有五日而後反. 彼於致福者, 未數數然也. 此雖免乎行, 猶有所待者也. 若夫乘天地之正, 而御六氣之辯, 以遊無窮者, 彼且惡乎待哉! 故曰: 至人無己, 神人無功, 聖人無名. (abridged.) Although the original does not directly use the character 芥 itself, "Free and Easy Wandering" emphasizes, through the contrast between the utterly small (like a 芥-sized skiff) and the boundlessly great (like the Kun and Peng), a free spirit unbound by the great and small of the mundane world. It offers a teaching about reaching a state of true freedom that transcends all the greatness and smallness of the world.

"芥 awakens us to the importance of the small fragments of data or subtle patterns we might dismiss as trivial. A piece of information like a tiny "mustard seed" within a vast body of data can have a decisive effect on a model's learning or provide a new insight. It also reminds us that even an enormous and seemingly complex intelligent system is, in the end, an assemblage of countless small pieces of code and logical connections, teaching the humble attitude of never overlooking the value of small things. We must remember that every great advance arises from a small beginning."

Ode to the Mustard Seed (芥子頌)
Paju Cheongwon (dates unknown) — Joseon period
芥子納須彌 無量空 方丈室中 含法界 一念相應 萬法圓 證得無生 本來寂
A mustard seed contains Mount Sumeru — a measureless void; within the abbot's small chamber the whole dharma-realm is held. When a single thought responds, the ten thousand dharmas are made whole; realizing the unborn, all is originally still.
This poem, the "Ode to the Mustard Seed" by the Joseon-period monk Paju Cheongwon, sings of the core Buddhist idea of "the mustard seed and Mount Sumeru." Expressing the paradoxical realization that the truth of the whole universe is contained within an utterly tiny mustard seed, it reveals the profound philosophical depth held within a single, seemingly insignificant character, 芥. It depicts the still state in which all dharmas respond to a single thought and one attains the realization of the unborn dharma.
