Core Proposition

$$\text{Ease with Situation} + \text{Transform with Conditions} + \text{Move with Nature} + \text{Act on Opportunity} + \text{No-Self, No-Selfishness, No-Attachment} = \text{Immortal (Xian)}$$

The Four Adaptations constitute a four-dimensional cultivation coordinate system: Situation (the circumstance dimension), Condition (the relational dimension), Nature (the essence dimension), Opportunity (the timing dimension). Each adaptation corresponds to an inner freedom: not imprisoned by circumstance, not bound by attachment, not coerced by convention, not defeated by missed opportunity.

II. Four-Dimension Analysis Matrix

Dimension Adaptation Core Question Correct Response Erroneous Response
Situation (遇) Ease with any situation What have I encountered? At ease, no resentment Complaining, comparing, blaming heaven and others
Condition (缘) Transform with conditions Who helps / who leaves? Grateful for aid; at peace in solitude Forcing, clinging, refusing to release
Nature (性) Move with your nature What does my true nature love? Act from nature, follow the Tao Self-coercion, acting against nature
Opportunity (机) Act on opportunity Has the moment arrived? All-in, burn all bridges Hesitation and loss, or forcing without a moment

III. Correspondence with the Three Realms of Immortality

Realm Characteristics Role of the Four Adaptations
First Realm (human → immortal transition) Earthly bonds fade; no fixation on wealth, status, beauty The Four Adaptations are the core practice for reaching the first realm
Second Realm (immortal state) No earthly ties, no attachment; no-self, no-selfishness; merged with the Tao The Four Adaptations deepen into complete freedom from attachment
Third Realm (higher immortal) Consciousness transcends the bounds of heaven and earth; body-mind-spirit at supreme freedom; limitless transformation The Four Adaptations have become inherent nature; no deliberate effort required

IV. Five Situation Models for Ease with Any Situation

(Derived from SS-03)

Situation Category Concrete Content Expression of Ease
Food and material Imperial banquet vs. sweet potato porridge vs. cornbread and pickles Eat joyfully; don't complain; treat it as fine food
Environment and climate Arctic cold vs. perpetual summer vs. remote mountain valley Able to survive — hold no resentment; enjoy the peace
Human connection Companionship vs. a decade without intimate contact Joyful with companions; quietly enjoy solitude
Unfulfilled wishes Wanted A; got B instead Remain cheerful; still able to laugh and converse freely
Innate conditions Others are gifted and healthy; I face illness and disadvantage Composed, harboring no resentment

Guiding metaphor Rope saws wood; water wears stone No fixed law; no fixed form
Domain of application Direction and aspiration Method and rhythm
