By “loka nirodha,” the Buddha did not mean the “destruction of the physical world” we experience. That would, of course, be an impossibility. A sentient being is attached to the ‘physical world’ only as long as the mind is defiled. Thus, ‘loka nirodha,’ or the ‘cessation of the world,’ refers to cleansing the mind, which is attained at the Arahant stage of Nibbāna.
Introduction
1. In the previous post, “Paṭicca Samuppāda – Introduction,” we started a new discussion on Paṭicca Samuppāda. In the “Saṁyutta Nikāya 12″ in the Sutta Piṭaka, there are over 100 suttas on Paṭicca Samuppāda.
- Recently I realized that these suttas are in a particular order. Although it is impossible to discuss all of them, following their progression helps us gain key insights. See “Sotāpanna Stage – Essential and Unnecessary Concepts.”
- Furthermore, I will discuss only those suttas relevant to our ongoing discussion on the connection between Paṭicca Samuppāda and Tilakkhana (and the Noble Truths).
- In my previous post, I noted that the first two suttas briefly introduce Paṭicca Samuppāda. See “Paṭicca Samuppāda – Introduction.”
2. The third sutta, “Paṭipadā Sutta (SN 12.3),” points out that the steps in the standard Paṭicca Samuppāda describe unwise actions (starting with “avijjā paccayā saṅkhāra”) that lead to future suffering (“jāti paccayā jarā, marana, soka-paridēva-dukkha-dōmanassupāyasā sambhavan’ti”). Therefore, it describes an average human’s micchā paṭipadā (immoral practices/way of living). Such future suffering can be stopped by stopping the steps in Paṭicca Samuppāda. That is accomplished by cultivating wisdom (knowledge of the Noble Truths) and removing avijjā. Once one understands the true nature of this world (Tilakkhana) at the Sotāpanna stage, one will follow sammā paṭipadā (correct practices/way of living) or the Noble Eightfold Path to get to Nibbāna.
- Then there are seven suttas (SN 12.4 through 12. 10) that describe how the most recent 7 Buddhas discovered how future suffering arises via the Paṭicca Samuppāda process, i.e., why an average human follows the micchā paṭipadā. (The teachings of a given Buddha last only a limited time. That is why each Buddha must discover this process independently.) At the same time, each Buddha figures out how to stop future suffering in the rebirth process, i.e., sammā paṭipadā.
- The following sutta in the series (of interest to the present discussion) clarifies a “loka.” In almost all English translations, “loka” is translated as “world” and gives the impression that the Buddha meant the “physical world around us” or even “the universe with its stars, planets, galaxies, etc.” But the Buddha meant something broader, as we see below.
Kaccānagotta Sutta (SN 12.15) – “Loka” Is Not the “Physical World”
3. The “Kaccānagotta Sutta (SN 12.15)” provides the first clues. Venerable Kaccānagotta asks the Buddha what is meant by “sammā diṭṭhi,” and the Buddha explains in the following way: “Dvayanissito khvāyaṁ, kaccāna, loko yebhuyyena—atthitañceva natthitañca.”
- The world (loka) repeatedly arises (and the rebirth process continues) mainly based on two extreme views:
(i) the world lasts forever (atthitañca), and
(ii) the world ends at the death of the present physical body (natthitañca). - Here the Buddha is NOT talking about the physical world with stars, planets, galaxies, etc. He is referring to the existence of a living being. Just like these days, people mainly had two extreme views: (i) a living being exists forever (i.e., the belief in a “soul” or “ātman“), and (ii) “one’s world” (loka) ends at the death of the physical body (the materialistic view of today).
4. Then, the Buddha explains that both those views are incorrect. A living being will exist (within the 31 realms) as long as the Paṭicca Samuppāda process is in effect and thus exists in a “loka.” Of course, most existences are filled with unbearable suffering. And that will not end until that living being starts comprehending the Four Noble Truths (or Tilakkhana or Paṭicca Samuppāda) and becomes a Sotāpanna.
Thus the Buddha almost always used the word “loka” to refer to the “world of a living being.” The next verse in this sutta also confirms that: “Tañcāyaṁ upayupādānaṁ cetaso adhiṭṭhānaṁ abhinivesānusayaṁ na upeti na upādiyati nādhiṭṭhāti: ‘attā me’ti. ‘Dukkhameva uppajjamānaṁ uppajjati, dukkhaṁ nirujjhamānaṁ nirujjhatī ’ti na kaṅkhati na vicikicchati aparapaccayā ñāṇamevassa ettha hoti. Ettāvatā kho, Kaccāna, sammā diṭṭhi hoti.”
Translated: “But someone with the right view does not cling to existence. He does not see any benefit of existence in this world, i.e., anything in this world is of no value (and thus should be considered mine or ‘attā me’ ti). He has no perplexity or doubts that what arises is only suffering; what ceases is only suffering. In this way, Kaccāna, there is CORRECT VIEW.”
5. The verses at the end of the sutta provide further confirmation:
“Sabbam atthī’ti kho, kaccāna, ayameko anto. ‘Sabbaṁ natthī’ti ayaṁ dutiyo anto.
Ete te, kaccāna, ubho ante anupagamma majjhena tathāgato dhammaṁ deseti:
– ‘avijjāpaccayā saṅkhārā; saṅkhārapaccayā viññāṇaṁ …pe… evametassa kevalassa dukkhakkhandhassa samudayo hoti.
– Avijjāya tveva asesavirāganirodhā saṅkhāranirodho; saṅkhāranirodhā viññāṇanirodho …pe… evametassa kevalassa dukkhakkhandhassa nirodho hotī’”ti.
Translated:
“‘All exists‘: Kaccāna, that is one extreme. ‘All does not exist’: that is the second extreme.
Without veering towards either of these extremes, the Tathāgata teaches the Dhamma by the middle:
– ‘With avijjā as condition, saṅkhāra arise; with saṅkhāra as condition, viññāṇa (and the rest of steps in PS)…. Such is the origin of this whole mass of suffering.
– But with the remainderless fading away and cessation of avijjā comes the ending of saṅkhāra; with the cessation of saṅkhāra, cessation of viññāṇa (and the rest of steps in PS)…. Such is the end of this whole mass of suffering.”
- Also, note that the Buddha has defined “all (sabba)” as “all that pertains to a living being,” i.e., the five aggregates/12 āyatana/6 dhātu/etc. Thus, by “all,” he did not restrict it to the physical world (that is, of course, a part of “all”). The five aggregates/12 āyatana/6 dhātu/etc include the physical and mental worlds. See “256 results for Kiñca AND sabbaṁ.”
- But in a sutta elsewhere in the Tipiṭaka, the Buddha did discuss the “physical world” too.
Rohitassa Sutta (AN 4.45) – A Sutta That Addresses the “Physical World”
6. In the “Rohitassa Sutta (AN 4.45),” Rohitassa Deva comes to the Buddha and asks whether it is possible to “travel to the end of the physical world.” Buddha answers that it is not possible. Rohitassa says he had confirmed this in a previous life, when he developed abhiññā powers as a yogi. With his manomaya kāya (gandhabba-like), he could travel the distance from one ocean to another in one stride. One day, he decided to see the “end of the world.” He said he traveled for a hundred years and died on the way.
Then the Buddha makes the following deeper point: “‘Yattha kho, āvuso, na jāyati na jīyati na mīyati na cavati na upapajjati, nāhaṁ taṁ gamanena lokassa antaṁ ñāteyyaṁ daṭṭheyyaṁ patteyyan’ti vadāmi. Na cāhaṁ, āvuso, appatvāva lokassa antaṁ dukkhassa antakiriyaṁ vadāmi. Api cāhaṁ, āvuso, imasmiṁyeva byāmamatte kaḷevare sasaññimhi samanake lokañca paññāpemi loka samudayañca loka nirodhañca loka nirodhagāminiñca paṭipadanti.“
- The following is the concept described by the Buddha in the above verse: “Without attaining Nibbāna, it is not possible to get to an ‘end of the world’ by traveling. Until the suffering (associated with the rebirth process) is ended, one cannot reach the ‘end of this world.” For it is in this physical body with its manomaya kaya with perception and mind (sasaññimhi samanake) restricted to moment-to-moment arising (byāmamatte) that I declare the arising and cessation of this world and the practice that leads to its cessation.”
7. Modern science admits that it cannot find “an edge to the universe.” The size of the universe is genuinely mind-boggling. The furthest a human has traveled in outer space is to the Moon. It is doubtful that humans can travel to even the nearest star system anytime soon, or probably ever.
- Distances between stars are too large to be measured in km or miles. Such vast distances are calculated in “light-years.” A light-year is the distance light travels in a year. The closest star to us is over four light-years away, meaning it will take a light beam over four years to travel to that star.
- For comparison, the distance to the Moon is only about 1.3 light-seconds! (Meaning it takes only 1.3 seconds for Moonlight to reach the Earth). Of course, even our fastest rockets take about three days to reach the Moon. Such a rocket will take over 80,000 years to get to the vicinity of the nearest star! You can Google that to verify.
- Then there are billions of stars in our galaxy and billions of such galaxies in the universe. There is no way to count all galaxies, and there may not even be a limit!
- That is why the Buddha said there is no point in investigating the physical universe. We will NEVER be able to even fully explore the closest stars and their planets, let alone the whole universe.
“Loka” Is One’s (Physical and Mental) World!
8. Therefore, it is critical to understand that when the Buddha referred to “loka,” he meant the existence of a living being.
- That is why the Buddha spoke of various types of loka encompassing the 31 realms: In one category, we have kāma loka, rupa loka, and arupa loka, with 11, 16, and 4 realms, respectively. Within the kāma loka, there are various “lokā“: manussa loka (human world), peta loka (loka of hungry ghosts), Deva loka, etc. The 20 realms in rupa loka and arupa loka are all inhabited by Brahmas and thus are commonly known as Brahma loka.
- A living being WILL ALWAYS live in one of those “worlds” until Parinibbāna is attained (the death of an Arahant). Thus, the “world’ does not cease to exist until then.
- Thus, we can also see that “cessation of the world” is the same as Nibbāna.
What Are”Loka Samudaya” and “Loka Niodha“?
9. When the current existence (say, human existence) ends, that is the end of the current “human bhava” in the “manussa loka.” But all of us (who are not Arahants) still have many accumulated kammic energies to “power up” different types of “bhava” for different kinds of “loka.”
- For example, that human may grasp a “Deva bhava” and thus be born in a “Deva loka.” Someone who has cultivated jhāna will grasp a “Brahma bhava” and thus be born in a “Brahma loka.” Yet another who has killed a parent will grasp a “niraya bhava” and be born in a “niraya.” For each of them, that will be their “loka” until that kammic energy runs out.
- However, any average living being will always have many possible bhavas. We have all accumulated many such “seeds” in our past lives, and maybe even a few in this life. That is why this process has no end until Arahanthood. The creation of such a kammic energy (to power up a new bhava) is the “arising of a ‘loka‘ or ‘loka samudaya‘.”
- That “loka samudaya” takes place via the Paṭicca Samuppāda process. It describes how such kammic energies accumulate via acting with avijjā. We will continue that discussion in the next post.
- Accumulation of new bhava (and grasping such accumulated bhava) will stop at the Arahant stage. Then no more existences in any realm in the loka, and that is “loka nirodha” or Nibbāna.
Paṭicca Samuppāda, Tilakkhana – Details of Four Noble Truths
10. One cannot fully comprehend the Four Noble Truths without understanding Paṭicca Samuppāda. Tilakkhana offers another way to view the same concepts.
