The Buddha uses the gradual purification of gold as a metaphor for mental cultivation through meditation. Just as a goldsmith removes coarse, medium, and subtle impurities until the gold is workable and radiant, a meditator abandons defilements in stages. This gradual refinement leads to deep collectedness of mind, forming the foundation for supernormal abilities and, ultimately, liberation.

AN 3.101  Paṁsudhovaka sutta - The Dirt Rinser

“Santi, bhikkhave, jātarūpassa oḷārikā upakkilesā paṁsuvālukā sakkharakaṭhalā. Tamenaṁ paṁsudhovako paṁsudhovakantevāsī doṇiyaṁ ākiritvā dhovati sandhovati niddhovati. Tasmiṁ pahīne tasmiṁ byantīkate santi jātarūpassa majjhimasahagatā upakkilesā sukhumasakkharā thūlavālukā. Tamenaṁ paṁsudhovako paṁsudhovakantevāsī dhovati sandhovati niddhovati. Tasmiṁ pahīne tasmiṁ byantīkate santi jātarūpassa sukhumasahagatā upakkilesā sukhumavālukā kāḷajallikā. Tamenaṁ paṁsudhovako paṁsudhovakantevāsī dhovati sandhovati niddhovati. Tasmiṁ pahīne tasmiṁ byantīkate athāparaṁ suvaṇṇasikatāvasissanti.

“Bhikkhus, there are coarse |impurities::blemishes, flaws, imperfections [upakkilesā]| in raw gold: dirt, sand, gravel, and pebbles. The dirt rinser or his apprentice, having poured the gold ore into a trough, washes it, rinses it, and cleanses it thoroughly. When these [coarse impurities] are abandoned and eliminated, there remain medium-sized impurities in the raw gold: fine gravel and coarse sand. The dirt rinser or his apprentice washes it, rinses it, and cleanses it thoroughly. When these [medium-sized impurities] are abandoned and eliminated, there remain subtle impurities in the raw gold: fine sand and black dust. The dirt rinser or his apprentice washes it, rinses it, and cleanses it thoroughly. When these [subtle impurities] are abandoned and eliminated, there remains just the gold dust.

Tamenaṁ suvaṇṇakāro suvaṇṇakārantevāsī jātarūpaṁ mūsāyaṁ pakkhipitvā dhamati sandhamati niddhamati. Taṁ hoti jātarūpaṁ dhantaṁ sandhantaṁ niddhantaṁ aniddhantakasāvaṁ, na ceva mudu hoti na ca kammaniyaṁ, na ca pabhassaraṁ pabhaṅgu ca, na ca sammā upeti kammāya. Hoti so, bhikkhave, samayo yaṁ suvaṇṇakāro suvaṇṇakārantevāsī taṁ jātarūpaṁ dhamati sandhamati niddhamati. Taṁ hoti jātarūpaṁ dhantaṁ sandhantaṁ niddhantaṁ niddhantakasāvaṁ, mudu ca hoti kammaniyañca pabhassarañca, na ca pabhaṅgu, sammā upeti kammāya. Yassā yassā ca pilandhanavikatiyā ākaṅkhatiyadi paṭṭikāya, yadi kuṇḍalāya, yadi gīveyyake, yadi suvaṇṇamālāyatañcassa atthaṁ anubhoti.

The goldsmith or his apprentice, having placed the gold dust into a |crucible::melting pot [mūsā]|, blows upon it, smelts it, and purifies it. At that point, the gold has been blown upon, smelted, and purified, but its |dross::(of gold) sediment, impurity [kasāva]| has not been entirely removed; it is not yet |pliable::soft, flexible [mudu]|, |malleable::ready, workable, suitable for use [kammañña]|, or |radiant::shining, bright, brilliant [pabhassara]|, but is brittle and not properly ready for working. But there comes a time, bhikkhus, when the goldsmith or his apprentice blows upon that gold, smelts it, and purifies it. At that point, the gold has been blown upon, smelted, and purified, with its dross entirely removed; it is pliable, malleable, and radiant, not brittle, and is properly ready for working. Then whatever kind of ornament the goldsmith wishes to make from it—whether a bracelet, earrings, a necklace, or a gold chain—he can achieve his purpose.

Evamevaṁ kho, bhikkhave, santi adhicittamanuyuttassa bhikkhuno oḷārikā upakkilesā kāyaduccaritaṁ vacīduccaritaṁ manoduccaritaṁ, tamenaṁ sacetaso bhikkhu dabbajātiko pajahati vinodeti byantīkaroti anabhāvaṁ gameti.

“So too, bhikkhus, for a bhikkhu devoted to the higher mind, there are coarse defilements: |bodily misconduct::killing living beings, harming others, theft, or sexual misconduct [kāyaduccarita]|, |verbal misconduct::false speech, harsh speech, divisive speech, idle chatter [vacīduccarita]|, and |mental misconduct::yearning with strong eagerness and desire, having ill will or hatred, delighting in harm [manoduccarita]|. An attentive and capable bhikkhu abandons these, dispels them, eliminates them, and brings them to nought.

Tasmiṁ pahīne tasmiṁ byantīkate santi adhicittamanuyuttassa bhikkhuno majjhimasahagatā upakkilesā kāmavitakko byāpādavitakko vihiṁsāvitakko, tamenaṁ sacetaso bhikkhu dabbajātiko pajahati vinodeti byantīkaroti anabhāvaṁ gameti.

When these [coarse defilements] are abandoned and eliminated, there remain for the bhikkhu devoted to the higher mind medium-sized defilements: |thoughts of sensuality::thoughts related to enjoyment of sensual pleasures, sexual thoughts [kāmavitakka]|, |thoughts of ill will::thoughts of resentment, anger, hatred [byāpādavitakka]|, and |thoughts of harming::idea of hurting, thought of cruelty [vihiṁsāvitakka]|. An attentive and capable bhikkhu abandons these, dispels them, eliminates them, and brings them to nought.

Tasmiṁ pahīne tasmiṁ byantīkate santi adhicittamanuyuttassa bhikkhuno sukhumasahagatā upakkilesā ñātivitakko janapadavitakko anavaññattipaṭisaṁyutto vitakko, tamenaṁ sacetaso bhikkhu dabbajātiko pajahati vinodeti byantīkaroti anabhāvaṁ gameti.

When these [medium-sized defilements] are abandoned and eliminated, there remain for the bhikkhu devoted to the higher mind subtle defilements: |thoughts about his family::thoughts on family, relatives, kins [ñātivitakka]|, thoughts on his country, and thoughts concerning his reputation. An attentive and capable bhikkhu abandons these, dispels them, eliminates them, and brings them to nought.

Tasmiṁ pahīne tasmiṁ byantīkate athāparaṁ dhammavitakkāvasissanti. So hoti samādhi na ceva santo na ca paṇīto nappaṭippassaddhaladdho na ekodibhāvādhigato sasaṅkhāraniggayhavāritagato.

When these [subtle defilements] are abandoned and eliminated, there remain just thoughts about the Dhamma. That |collectedness::stability of mind, stillness of mind, mental composure [samādhi]| is not yet peaceful or sublime, not obtained by tranquility, not attained to |unification::singleness, integration [ekodibhāva]| of mind, but is |held in place and restrained by intention::reined in and checked by volition [sa + saṅkhāra + niggayha + vārita + gata]|.

Hoti so, bhikkhave, samayo yaṁ taṁ cittaṁ ajjhattaṁyeva santiṭṭhati sannisīdati ekodi hoti samādhiyati. So hoti samādhi santo paṇīto paṭippassaddhiladdho ekodibhāvādhigato na sasaṅkhāraniggayhavāritagato. Yassa yassa ca abhiññā sacchikaraṇīyassa dhammassa cittaṁ abhininnāmeti abhiññā sacchikiriyāya tatra tatreva sakkhibhabbataṁ pāpuṇāti sati satiāyatane.

But there comes a time, bhikkhus, when that mind becomes internally steadied, calmed, |unified::one-pointedness, with oneness, integrated, well-composed, concentrated [ekagga]|, and |collected::composed, settled [samāhita]|. That collectedness is peaceful and sublime, obtained by tranquility, and attained to unification of mind; it is not held in place and restrained by intention. Then, there being a suitable basis, the bhikkhu is capable of realizing any phenomenon realizable by |direct knowledge::experiential understanding [abhiññāya]| by directing his mind towards it.

So sace ākaṅkhati: ‘anekavihitaṁ iddhividhaṁ paccanubhaveyyaṁekopi hutvā bahudhā assaṁ, bahudhāpi hutvā eko assaṁ; āvibhāvaṁ, tirobhāvaṁ; tirokuṭṭaṁ tiropākāraṁ tiropabbataṁ asajjamāno gaccheyyaṁ, seyyathāpi ākāse; pathaviyāpi ummujjanimujjaṁ kareyyaṁ, seyyathāpi udake; udakepi abhijjamāne gaccheyyaṁ, seyyathāpi pathaviyaṁ; ākāsepi pallaṅkena kameyyaṁ, seyyathāpi pakkhī sakuṇo; imepi candimasūriye evaṁmahiddhike evaṁmahānubhāve pāṇinā parimaseyyaṁ parimajjeyyaṁ; yāva brahmalokāpi kāyena vasaṁ vatteyyan’ti, tatra tatreva sakkhibhabbataṁ pāpuṇāti sati satiāyatane.

If he wishes: ‘May I realize the various kinds of |psychic powers::supernormal abilities, psychic potency, spiritual power [iddhi]| such as—being one, become many; having been many, become one; appear and disappear; pass through walls, enclosures, and mountains unhindered as if through space; dive into and emerge from the earth as if it were water; walk on water without sinking as though on solid ground; fly cross-legged through the sky, like a bird; with hand, touch and stroke the moon and the sun, so mighty and powerful; with the body, exercise control even as far as the |Brahmā world::heavenly realm|,’ then, in each case, he is capable of realizing it, there being a suitable basis.

If he wishes: ‘May I, with the |divine ear element::clairaudience, the divine auditory faculty [sotadhātu]|, which is purified and surpasses the human level, hear both kinds of sounds, divine and human, whether distant or near,’ he is capable of realizing it, there being a suitable basis.

But these beings, engaged in good bodily, verbal, and mental conduct, not revilers of the Noble Ones, holding right views and undertaking actions based on right views—upon the breaking up of the body, after death, have arisen in a good destination, the heavenly world. In this way, may I, with the divine eye, purified and surpassing the human vision, see beings as they pass away and are reborn, inferior and superior, beautiful and unattractive, in fortunate and unfortunate destinations, and understand beings according to their actions,’ he is capable of realizing it, there being a suitable basis.
