自力 is a word in Chinese, Japanese Kanji, old Korean, and Buddhist term meaning: the power within oneself; self-sufficient; by oneself; self-made; self-power; inner ability.

內力 is the shorter version of inner strength (can also be translated as “internal force”). The first character holds the meaning of “inner” or “internal.” The second character means “power,” “force,” or “strength.”

內力 is a Kung Fu way of talking about an inner power or strength from within. This is a way to express “inner chi.” This is something that you might hear in a real Chinese Kung Fu movie.

While understood in Chinese and Japanese, this can have a secondary meaning of “inner stress” in Japanese.

內在力量 is the slightly-verbose way to say inner strength.

The first two characters mean “intrinsic” or “inner.” The second two characters mean “power,” “force” or “strength” (especially physical strength). 內在力量 is more a short phrase rather than just a word in Chinese and Korean. This can sort of be understood in Japanese but it's not normal/proper Japanese.

内面の強さは外見の良さに勝る is a Japanese proverb that literally translates as “inner/internal strength/power [versus] outward-appearance [the] merit/virtue/good quality [does] excel/surpass/exceed/outweigh.”

More naturally in English, this would be “Inner Strength Outweighs Outward Appearance.”

Note: Because this selection contains some special Japanese Hiragana characters, it should be written by a Japanese calligrapher.

自強 is the kind of inner strength that applies to a person who has will-power and can inspire themselves to do great things.

自強 can also be the creed of a person that always pursues self-improvement.

Other translations: self-strengthening, striving for improvement, self-improvement, striving to become stronger, and self-renewal.

Chapter 27 of the Daodejing reveals a profound truth about mastery: the highest skill leaves no trace, requires no force, and appears almost invisible.

善行無轍跡， 善言無瑕謫， 善數不用籌策， 善閉無關鍵而不可開， 善結無繩約而不可解。 是以聖人常善救人， 故無棄人； 常善救物， 故無棄物。 是謂襲明。 故善人者，不善人之師； 不善人者，善人之資。 不貴其師，不愛其資， 雖智大迷， 是謂要妙。

The sage moves through life with such natural harmony that nothing seems imposed; doors need no locks, knots require no rope, and actions leave no mark behind.

This is the essence of wúwéi (effortless action), where true ability arises from deep alignment with the Tao rather than deliberate effort.

At its heart, this chapter teaches compassion without exception. The sage “abandons no one and nothing,” recognizing value in all people and all things. Even those who seem flawed or unrefined are not rejected, but understood as part of a greater whole with each person both a student and a teacher in the unfolding of life.

Laozi reminds us that wisdom is not about perfection or control, but about subtle awareness. The truly skilled individual does not rely on tools, rules, or rigid structures; instead, they embody an intuitive understanding that makes their actions naturally complete.

In this way, excellence becomes quiet, effortless, and beyond imitation.

This teaching also reflects a deeper philosophical insight: Opposites are interdependent. The “good” person learns from the “not good,” and the “not good” provides the material for growth. To reject either is to misunderstand the balance of existence itself.

As calligraphy, Daodejing Chapter 27 serves as a reminder to cultivate inner mastery rather than outward display. It is a meditation on refinement, humility, and the quiet power of skill perfected through harmony with the natural order.
