Within the depth-psychology corpus assembled here, 'Firmness' emerges primarily through the Taoist I Ching tradition as a cardinal psycho-spiritual virtue paired inextricably with its complementary opposite, flexibility. Liu I-ming's systematic treatment, rendered into English by Thomas Cleary, provides the most developed account: firmness is identified with yang, with heaven, with 'ready knowledge,' with decisiveness, strength, and an incorruptible inner energy that neither wealth nor adversity can dislodge. Far from denoting mere rigidity, it names a dynamic quality of will that must be deployed with precise timing — too much firmness without flexibility courts the catastrophic excess of the 'proud dragon.' Richard Wilhelm's rendering of the I Ching contributes a parallel strand, identifying Duration (Hêng) as the hexagram that brings 'firmness of character in the frame of time,' suggesting that character itself is constituted by the stable self-coherence that firmness names. The central tension across all major voices concerns the relationship between firmness and flexibility: neither alone is sufficient; the consummated practitioner must integrate both. This makes firmness not a static trait but a dynamically balanced force — one that preserves the 'celestial energy' against mundane dissolution and grounds the capacity for imperturbable action in the world.
Firmness is strength, sturdiness, decisiveness, power, energy, keenness. Those who use firmness well cannot be corrupted by wealth and rank, cannot be moved by poverty and lowliness, cannot be suppressed by aggression.
This passage provides Liu I-ming's canonical positive definition of firmness as the irreducible yang energy that renders the practitioner incorruptible by external circumstance.

Firmness is strength, sturdiness, decisiveness, power, en-ergy, keenness. Those who use firmness well cannot be corrupted by wealth and rank, cannot be moved by pov-erty and lowliness, cannot be suppressed by aggression.
Liu I-ming's Eight Elements framework identifies firmness as the foundational quality of imperturbability, exemplified by Mencius whose abundant energy made his mind unmovable by forty.
, The Taoist I Ching, 1986thesis
The quality of firmness is based on strength, the quality of flexibility is based on receptivity. Strength is ready knowledge, receptivity is simple capacity. Ready knowledge is the innate knowledge in people, simple capacity is the innate capacity in people.
This passage grounds firmness metaphysically, equating it with 'ready knowledge' — the innate celestial yang that is the ontological basis of human cognition and moral strength.
, The Taoist I Ching, 1986thesis
Heaven is firm, earth is flexible. Heaven is strength; stronger than strong, it is the ultimate of firmness. Of that which is firm, nothing is firmer than heaven.
Liu I-ming identifies firmness with heaven itself as the cosmological archetype — the ceaseless circulation of yang energy that creates and sustains all things.
, The Taoist I Ching, 1986thesis
In general, the way to act with strength and use firmness requires appropriate timing. Creation, development, fruition, and consummation can then be strong everywhere, and strength cannot be damaged anywhere.
Firmness is shown to be not an absolute quantity but a time-conditioned quality: genuine firmness requires the wisdom of appropriate timing lest it become excess and invite reversal.

In general, the way to act with strength and use firmness requires appro-priate timing. Creation, development, fruition, and consummation can then be strong everywhere, and strength cannot be damaged anywhere.
Liu I-ming insists that firmness deployed without temporal discernment reverts to its opposite — the proud dragon who overreaches and must suffer regret.

Hêng, DURATION (32). This hexagram brings about firmness of character in the frame of time. It shows wind and thunder constantly together; hence there are manifold movements and experiences, from which fixed rules are derived, so that a unified character results.
Wilhelm identifies Duration as the hexagram that temporally constitutes firmness of character — not a fixed essence but a pattern that coheres through repeated cycles of change.

When practitioners of the Tao activate the energy of will and go directly forward, arriving at the remote by way of the near at hand, this should be like the movement of thunder; only then can they rise up with firmness, and not be subject to compulsion by human desires.
Firmness here is a soteriological achievement: the capacity to advance in practice without capitulation to the compulsive force of human desires, modeled on the irrepressible movement of thunder.

This is losing tranquility by softness injuring firmness.
A concise formulation of the pathological dynamic: when softness predominates and injures firmness, the achieved tranquility is lost and the cultivated gold elixir dissipates.

When strength is used flexibly, flexibility is the root and firmness is the branch. Not being excessively firm, not damaging the flexibility, firmness and flexibility are united, and one is able to change adaptively according to circumstances.
Liu I-ming inverts the usual hierarchy: when properly integrated, flexibility is the root and firmness the branch — excessive firmness damages the very flexibility that gives it life.

Strength and illumination both working, firmness and flexibility balancing each other, inwardly not losing oneself, outwardly not hurting others, round and bright, clean and bare, one stands in the midst of myriad things without being inhibited by myriad things.
Firmness paired with flexibility and illumination constitutes the realized state: an unconstrained presence within phenomenal reality, neither withdrawn nor overwhelmed.

In the end of great possession, firmness and flexibility match each other, strength and lucidity are as one; integrated with celestial principle, the gold elixir crystallized, one's fate depends on oneself and not on heaven.
The culmination of great possession is the perfect matching of firmness and flexibility — the state in which self-determination replaces dependence on external celestial mandate.

Going forward, or retreating? His mind is perplexed. Favorable to have a warrior's firmness and steadfastness. His will is controlled.
Alfred Huang's translation frames firmness in characteristically martial terms — the warrior's steadfastness as the antidote to the perplexed, wavering mind caught between advance and retreat.
