How the Outflows Sustain Saṃsāra: A Penetrative Analysis of Āsavā in Early Buddhism Reflections by Bhante Dr. Chandima

1. What Is to Be Understood about the Āsavā

Āsavā bhikkhave veditabbā, āsavānaṃ nidānasambhavo veditabbo, āsavānaṃ vemattatā veditabbā, āsavānaṃ vipāko veditabbo, āsavanirodho veditabbo, āsavanirodhagāminī paṭipadā veditabbā” ti iti kho panetaṃ vuttaṃ, kiñcetaṃ paṭicca vuttaṃ.

Monks, the outflows are to be understood;

the origin of the outflows is to be understood;

the diversity of the outflows is to be understood;

the result of the outflows is to be understood;

the cessation of the outflows is to be understood;

and the path leading to the cessation of the outflows is to be understood.

This was said — but with reference to what was it said?”

• Here the Buddha applies the same sixfold penetrative analysis to the āsavā. Āsavā are not surface emotions — they are deep-seated currents that “flow out” into repeated existence. Their full understanding marks the threshold of arahantship.

2. The Three Āsavā

Tayome, bhikkhave, āsavā — kāmāsavo, bhavāsavo, avijjāsavo.

Monks, there are these three outflows:

the outflow of sensuality,

the outflow of becoming,

and the outflow of ignorance.

• These three summarize the entire engine of saṃsāra: kāmāsava — addiction to sense pleasure, bhavāsava — craving for continued existence, avijjāsava — fundamental not-knowing. Ignorance stands at the root.

3. The Origin of the Āsavā

Katamo ca bhikkhave āsavānaṃ nidānasambhavo: avijjā bhikkhave āsavānaṃ nidānasambhavo.

And what, monks, is the origin of the outflows? Ignorance (avijjā) is the origin of the outflows.

• This is decisive: Avijjā is the primary condition for all āsavā. Not seeing the Four Noble Truths allows desire and becoming to keep flowing.

4. The Diversity of the Āsavā (according to destinations)

Katamā ca bhikkhave āsavānaṃ vemattatā: atthi bhikkhave āsavā nirayagāminiyā, atthi āsavā tiracchānayonigāminiyā, atthi āsavā pettivisayagāminiyā, atthi āsavā manussalokagāminiyā, atthi āsavā devalokagāminiyā. Ayaṃ vuccati bhikkhave āsavānaṃ vemattatā.

And what, monks, is the diversity of the outflows?

There are outflows leading to hell;

outflows leading to the animal realm;

outflows leading to the domain of ghosts;

outflows leading to the human world;

outflows leading to the deva world.

This is called the diversity of the outflows.

• The āsavā shape rebirth destinations. They are not abstract defilements — they determine realms of existence.

5. The Result (vipāka) of the Āsavā

Katamo ca bhikkhave āsavānaṃ vipāko: yaṃ kho bhikkhave avijjāgato tajjaṃ tajjaṃ attabhāvaṃ abhinibbatteti puññabhāgiyaṃ vā apuññabhāgiyaṃ vā, ayaṃ vuccati bhikkhave āsavānaṃ vipāko.

And what, monks, is the result of the outflows? When one is overwhelmed by ignorance, one gives rise to corresponding forms of existence — wholesome or unwholesome. This is called the result of the outflows.

• Here again attabhāva (future identity) appears. The āsavā literally manufacture renewed existence, whether fortunate or unfortunate.

6. The Cessation of the Āsavā

Katamo ca bhikkhave āsavanirodho: avijjānirodho bhikkhave āsavanirodho.

And what, monks, is the cessation of the outflows?

With the cessation of ignorance comes the cessation of the outflows.

• This is the heart of liberation:  when avijjā ends, all āsavā dry up. This is the defining feature of arahantship: khīṇāsava — “one whose outflows are destroyed."

7. The Path Leading to the Cessation of the Āsavā

Ayameva ariyo aṭṭhaṅgiko maggo āsavanirodhagāminī paṭipadā. Seyyathīdaṃ: sammādiṭṭhi sammāsaṅkappo sammāvācā sammākammanto sammāājīvo sammāvāyāmo sammāsati sammāsamādhi.

This very Noble Eightfold Path is the way leading to the cessation of the outflows: Right View, Right Intention, Right Speech, Right Action, Right Living, Right Effort, Right Mindfulness, Right Concentration.

• The āsavā are eliminated only through complete path cultivation, especially Right View, which directly uproots ignorance.

8. The Noble Disciple’s Penetrative Understanding

Yato ca kho bhikkhave ariyasāvako evaṃ āsave pajānāti… so imaṃ nibbedhikaṃ brahmacariyaṃ pajānāti āsavanirodhaṃ.

When a noble disciple understands the outflows in this way — their origin, diversity, result, cessation, and the path leading to cessation — then he understands this penetrative holy life that leads to the ending of the outflows.

• Nibbedhika means “piercing through.” This insight does not merely weaken defilements — it cuts them at the root.

9. Summary Statement

Āsavā bhikkhave veditabbā… āsavanirodhagāminī paṭipadā veditabbā” ti iti yantaṃ vuttaṃ, idametaṃ paṭicca vuttaṃ.

Monks, the outflows are to be understood… the path leading to the cessation of the outflows is to be understood.

What was said in this way was said with reference to this.

Further Notes on the Āsavā

Here the Buddha reveals the deepest layer of bondage:

āsavā are the subterranean currents driving rebirth.

When ignorance ceases,

the outflows dry up,

becoming ends,

and Nibbāna is realized.

This completes the progressive depth:

kāma → vedanā → saññā → āsavā

—from surface experience to root ignorance.

1. The Sabbāsava Sutta MN 2 teaches that there are seven methods for eliminating the āsavas (mental outflows/taints)

1. Outflows Abandoned by Seeing (Dassana)

• Ordinary people do not know:

  • what should be attended to

  • what should not be attended to.

• Because of this they pay attention to wrong questions, such as:

  • Was I in the past?

  • What was I in the past?

  • Shall I be in the future?

  • Am I?

  • Am I not?

  • Where did this being come from?

  • Where will it go?

Result

These reflections produce six wrong views, such as:

• Self exists.

• Self does not exist.

• I perceive self with self.

• I perceive self with not-self.

• Eternalist views about the self.

These views are called:

• A thicket of views

• A wilderness of views

• A fetter of views

Because of these views, people remain bound to:

• birth

• aging

• death

• sorrow

• suffering.

Noble disciple's approach

The well-trained disciple instead reflects wisely on:

• This is suffering.

• This is the origin of suffering.

• This is the cessation of suffering.

• This is the path leading to the cessation of suffering.

Result

Three fetters are abandoned:

• Personality view (sakkāya-diṭṭhi)

• Doubt (vicikicchā)

• Attachment to rites and rituals (sīlabbata-parāmāsa)

These are taints abandoned by seeing.

2. Outflows Abandoned by Restraining (Saṃvara)

A monk restrains the six sense faculties:

• Eye

• Ear

• Nose

• Tongue

• Body

• Mind

Without restraint:

• defilements arise

• agitation and distress arise.

With restraint:

• taints do not arise.

3. Outflows Abandoned by Using (Paṭisevana)

The four requisites are used with wise reflection.

Robe/clothing

Used only:

• for protection from cold and heat

• from insects and weather

• for modesty.

Almsfood/food

Used:

• not for pleasure or beautification

• only to sustain the body

• to support the holy life.

Lodging

Used:

• for protection from weather

• for seclusion and meditation.

Medicine

Used:

• to cure illness

• for maintaining health.

Using requisites wisely prevents taints.

4. Outflows Abandoned by Enduring (Adhivāsana)

A practitioner patiently endures:

• heat and cold

• hunger and thirst

• insects and discomfort

• harsh speech

• painful bodily feelings.

Through endurance, defilements do not arise.

5. Outflows Abandoned by Avoiding (Parivajjana)

One avoids harmful situations, such as:

• dangerous animals

• unsafe environments

• unsuitable places

• bad companions

• suspicious or immoral situations.

Avoidance prevents the arising of defilements.

6. Outflows Abandoned by Removing (Vinodana)

A practitioner actively removes unwholesome thoughts:

• sensual desire

• ill will

• cruelty

• other unwholesome mental states.

These thoughts are:

• abandoned

• removed

• eliminated

• destroyed.

7. Outflows Abandoned by Developing (Bhāvanā)

One develops the Seven Factors of Enlightenment (satta bojjhaṅgā):

1. Mindfulness (sati)

2. Investigation of phenomena (dhammavicaya)

3. Energy (viriya)

4. Joy (pīti)

5. Tranquillity (passaddhi)

6. Concentration (samādhi)

7. Equanimity (upekkhā)

These are developed based on:

• seclusion

• dispassion

• cessation

• relinquishment.

2. The ideal state of enlightened beings is described as khīṇāsava—one who has completely destroyed the āsavas (mental outflows/taints) (Alagaddūpama Sutta MN 22)

evaṃ svākkhāto, bhikkhave, mayā dhammo uttāno vivaṭo pakāsito chinnapilotiko. evaṃ svākkhāte, bhikkhave, mayā dhamme uttāne vivaṭe pakāsite chinnapilotike ye te bhikkhū arahanto khīṇāsavā vusitavanto katakaraṇīyā ohitabhārā anuppattasadatthā parikkhīṇabhavasaṃyojanā sammadaññā vimuttā, vaṭṭaṃ tesaṃ natthi paññāpanāya.

Bhikkhus, thus the Dhamma has been well proclaimed by me—clear, open, revealed, and stripped of its patchwork coverings.When the Dhamma has been thus well proclaimed by me—clear, open, revealed, and stripped of its patchwork coverings—those bhikkhus who are arahants, whose taints (āsavas) are destroyed, who have lived the holy life, done what had to be done, laid down the burden, reached their own true goal, completely destroyed the fetters of existence, and are liberated through perfect knowledge—for them there is no more round of rebirth to be declared.
