Self-Nature (Buddha-Nature): What Were We, Before All of This?¶

I. The Question at the Root of All Practice¶

Every tradition of spiritual cultivation, beneath its methods and rituals, is circling the same question:

What am I, at the deepest level?

Buddhism's answer: you are originally a Buddha.

But what does "originally a Buddha" actually mean? Where is this "original"? What would it feel like to find it?

The three terms — Self-Nature (自性), Buddha-Nature (佛性), and Tathāgata's Original Nature (如来本性) — are three ways of pointing at the same answer.

II. Three Words, One Thing¶

Guide Xuefeng's starting point is blunt:

Self-Nature is Buddha-Nature. Buddha-Nature is Tathāgata's Original Nature.

He adds: whether you call it a potato, a yam, or a sweet potato, you're talking about the same edible thing. The names belong to different traditions; the thing they point to is the same.

III. The Water in Every Cup¶

Picture a table with four glasses on it: tea, milk, beer, saline solution.

Different colors. Different tastes. Different uses. You'd never confuse them.

But they all share one ingredient — water.

Guide Xuefeng uses exactly this image:

Tea, mung bean soup, milk, coffee, cola, alcohol, blood, penicillin injections — they all share one common constituent: water. This water is Self-Nature, Buddha-Nature, Tathāgata's Original Nature. That is the principle behind "all sentient beings possess Buddha-Nature."

Every living thing — elephant or ant, saint or sinner, human or bird — shares the same underlying "water" at the deepest layer of its existence. This shared water is Tathāgata's Original Nature. And because every life is, at its foundation, the same "One," the Buddhist claim that "all beings are equal" is not a moral aspiration but a statement of fact.

IV. But What Shows Up Is Tea, Not Water¶

Here is a distinction that matters:

When you drink tea, you taste tea — not water. Tea's main ingredient is water, but what tea expresses is tea's own character.

Xuefeng calls this the difference between Self-Nature (the water / the wood) and Heavenly-Nature (the tea / the furniture):

Self-Nature: the universal original substrate — water in every liquid, wood in every piece of furniture
Heavenly-Nature: the distinctive character of each specific thing — what a table is for, what milk tastes like

His point: the Greatest Creator wants every being to fully express its own Heavenly-Nature — to be what it is, do what it does, fulfill its role. A table does table-things, not wood-things. If milk tried to behave like pure water, it would be abandoning its nature, and trouble would follow.

So "restoring original nature" does not mean erasing your personality or becoming a blank. It means clearing the clutter — fear, craving, jealousy, ego-attachment — that covers over your natural way of being, so that Heavenly-Nature can shine through cleanly.

V. The Five Sentences That Changed Buddhist History¶

When the Sixth Patriarch Huineng experienced his awakening, he reportedly spoke five sentences. These five sentences appear in the Lifechanyuan framework as the most precise description of what Self-Nature actually is:

How wondrous — Self-Nature is originally pure. How wondrous — Self-Nature is originally unborn and undying. How wondrous — Self-Nature is originally complete and sufficient. How wondrous — Self-Nature is originally unmoved. How wondrous — Self-Nature can give birth to the ten thousand dharmas.

In plain terms:

Originally pure — your nature was never actually corrupted; it's merely covered
Unborn and undying — it doesn't begin at birth and end at death; it was there before, it continues after
Originally sufficient — nothing needs to be added; everything you need is already present within
Originally unmoved — no matter what happens in the world, your deepest nature remains still
Generative — all phenomena, all laws, all dharmas arise from this

The third point is the pivot of the whole cultivation philosophy.

VI. Why "Restore," Not "Achieve"?¶

Most of us assume spiritual practice is about becoming better — accumulating wisdom, building virtue, gradually earning a higher state.

Xuefeng inverts this:

LIFE does not require anything to be added. It only requires the restoration of original nature.

If Self-Nature is "originally sufficient," then the project was never about gaining something new. It was always about uncovering what was already there.

Think of a mirror that's been in a dusty room for twenty years. The mirror doesn't need to be given the ability to reflect — that ability was there from the start. It just needs the dust wiped off.

This matters practically. The purer the restoration, the higher the life's quality and the longer its endurance. Xuefeng traces a progression:

Ordinary person → Worthy person → Celestial person → Terrestrial immortal → Divine immortal → Angel (heavenly immortal or Buddha)

Each stage is not a new acquisition but a deepening return.

VII. So What Does "Seeing the Nature" Actually Mean?¶

Xuefeng offers a quietly remarkable sequence of questions:

Is my house me? No — when I had no house, I was still me. Are my eyes me? No — even blind, I am still me. Is my heart me? No — with a transplanted heart, I am still me. ... None of these are me. So who am I? I am the Tathāgata.

Strip away everything that can be taken away, everything that can change, everything that has a specific shape — and what remains, the one thing that cannot be removed or identified as any particular form, is the Tathāgata. That is Self-Nature.

Seeing the Tathāgata in that instant is the instant of becoming Buddha.

One important note: Xuefeng adds that seeing the nature is not just a spontaneous flash of intuition. It requires a foundation:

"To illuminate the mind and see the nature, one must first understand the origin of LIFE, the structure of LIFE, the essence of LIFE, and the evolution of LIFE."

The cosmological and LIFE-theory framework of Lifechanyuan is, in part, precisely this preparatory understanding.

VIII. A Final Reminder¶

Xuefeng ends his core essay on Self-Nature with words that cut through everything he just explained:

In truth, all this analysis is of limited benefit. The simplest gateway: shed worry, sorrow, and fear; achieve, as much as possible, a mind with no attachments and no fixed dwelling; reach, as best you can, a state of no-self and no-form. Achieve this — and you've already become Buddha, already entered the world of bliss.

All the concepts — Self-Nature, Buddha-Nature, Tathāgata's Original Nature — are signposts, not destinations.

Put them down. Let go of the dust. The mirror was already there.
