Brief note: I’m on for almost back to back retreats at IMS and Dhammasukha in July which will likely see little to no internet interactions until near end of July for another Meditation Q & A and to start editing a cohosted swapcast with a monastic guest recorded yesterday.
The last half of the chapter 11 of Buddhadhamma is auto scheduled to publish July 12
Post Retreat Update: During the Questions and Answers (which don’t seem to be published as of July 25, 2026) at the end of the talks for the 31 Realms Retreat with Ajahn Punnadhammo I mentioned only few things that the Ajahn wasn’t familiar with and I couldn’t remember where I had heard them. Here are those references via Ai, one a Mahayana recount on spontaneous rebirth out of a hell realm and the other on the Buddha suggesting knowing the 27 lunar mansions or star clusters along the moon’s path across the night sky for survival purposes for wilderness dwelling monks:
You are thinking of a famous Buddhist narrative often recounted in Mahāyāna texts (such as the Sūtra on Repaying the Kindness of the Buddha or the Sūtra of the Wise and the Foolish) about the first time the Buddha awakened the Bodhi-mind (Bodhicitta)—the altruistic mind of enlightenment.
It is also frequently retold by modern Buddhist teachers, such as Thich Nhat Hanh and Lama Zopa Rinpoche.
The Story: Pushing the Fiery Cart in Hell
In a distant past life, long before achieving Buddhahood, the future Shakyamuni Buddha committed negative karma that caused him to be born in one of the hot hell realms (Naraka).
- The Suffering: In this hell realm, he and another hell-being were forced by an ox-headed or lion-faced hell guardian to pull an impossibly heavy, flaming iron cart/chariot across scorching ground. The guards relentlessly whipped and stabbed them with iron forks whenever they slowed down.
- The Act of Compassion: The future Buddha saw that his companion was physically collapsing, utterly exhausted, and screaming in agony as the guard brutally beat him. Seeing another’s intense suffering, a profound, spontaneous feeling of compassion arose in the future Buddha.
- The Sacrifice: He stepped forward and said to the hell guard: “This person is too weak and pitiful. Please let him rest. Put his rope on my shoulders, and I will pull the cart for both of us.”
- The Immediate Rebirth: The brutal hell guard became infuriated by this act of mercy and struck the future Buddha in the head/neck with his iron trident or mace, killing him on the spot.
Because his final thought at the moment of death was pure, selfless compassion and a desire to take on another’s suffering (a moment of Bodhicitta), his heavy negative karma was instantly purified. He escaped hundreds of kalpas (eons) of hellish punishment and was immediately reborn in a higher realm (often described as a heavenly realm or human realm).
Why the Story is Famous
In Buddhist philosophy, this story illustrates three major points:
- The Power of Mind/Intention (Cetanā): Karma is ultimately rooted in intention. Even in the deepest, darkest states of mind or existence (represented by Hell), a single genuine spark of selflessness and love can radically transform one’s karmic trajectory.
- The Birth of the Bodhisattva Vow: It marks the mythic origin point where the future Buddha first planted the seed to become a Bodhisattva—a hero dedicated to freeing all beings from suffering.
- No Place is Beyond Compassion: As Thich Nhat Hanh often reflected on this story, it shows that no matter how terrible a situation or environment is, the capacity for compassion is never permanently lost.
In the Theravāda tradition, there is a subtle but very important distinction to make:
A future Buddha (Bodhisatta) can be born in a hell realm, and the Theravāda Jātaka commentary explicitly records that the Bodhisatta spent time in hell in past lives. However, once a Bodhisatta receives a formal, irreversible prediction (Niyata-Vyākaraṇa) from a living Buddha, their spiritual development prevents them from ever falling into the deepest, most absolute forms of hell (such as Avīci).
1. Did the Bodhisatta Ever Go to Hell in Theravāda?
Yes. In the Theravāda Jātaka commentaries, the Bodhisatta experienced the lower realms, including hell (Niraya), during his long journey through saṃsāra:
- The Temiya Jātaka (Mūgapakkha Jātaka): Prince Temiya (the Bodhisatta) remembers his past life where he served as a king for 20 years and had to pass judicial sentences. Because of the heavy karma of taking lives/punishing criminals as a ruler, he spent 80,000 years in the Ussada Hell (a hell realm) suffering immense torment. This terror of returning to hell was so profound that in his present life as Temiya, he feigned being mute, deaf, and crippled for 16 years just so his father wouldn’t force him to become king.
- The Sanjiva Jātaka: The Bodhisatta explicitly references times in his past lives when unskilful actions led to rebirth in lower realms before his spiritual momentum became unshakeable.
2. The Nuance: The “18 Ineligible States” (Abhabbaṭṭhāna)
You might have heard that a Bodhisatta cannot go to hell. This comes from a specific Theravāda rule established in the commentaries (like the Sutta Nipāta commentary and the Buddhavaṃsa commentary).
Once a Bodhisatta reaches the point of Definite Prediction (Niyata Bodhisatta)—when a past Buddha looks into the future and confirms, “You will become a Buddha named Gautama”—he acquires the 18 Ineligible States (Abhabbaṭṭhāna). From that exact moment onward, he can never be born into:
- Avīci Hell (or the Inter-Cosmic Hells / Lokantarika): The deepest, uninterrupted hells reserved for the absolute worst acts.
- The Formless Realms (Arūpavacara): Being trapped in pure mind-states with no physical form, where you cannot practice the Perfections (pāramīs) or help beings.
- The Unconscious Realm (Asaññasatta): Where there is physical body but no consciousness.
- Extreme / Severe Impairments: Born permanently blind, deaf, insane, or as an animal smaller than a quail or larger than an elephant.
3. Why Can’t a Fully Confirmed Bodhisatta Fall into Deep Hell?
In Theravāda philosophy, this protection isn’t a magical shield granted by an outside force; it is the natural law of kammic momentum:
- Power of the Ten Perfections (Pāramīs): A confirmed Bodhisatta spends eons relentlessly cultivating Generosity (Dāna), Morality (Sīla), Renunciation (Nekkhamma), Wisdom (Paññā), and Energy (Viriya). This vast reservoir of bright, wholesome karma (kusala-kamma) far outweighs his unwholesome karma.
- Inability to Commit Heinous Crimes: A confirmed Bodhisatta is incapable of committing the five Ānantarika-kamma (killing a mother, killing a father, killing an Arahant, drawing the blood of a Buddha, or creating a schism in the Sangha). Since he cannot commit these acts, the karmic doorway to Avīci hell is permanently shut.
- Efficiency of the Path: A Bodhisattva’s primary “job” is to mature his pāramīs and help other beings. Spending millions of years incapacitated in the absolute worst hell realms would stall the realization of Buddhahood inefficiently. His refined mental state organically protects him from plunging into the deepest darkness.
The reference you are thinking of comes primarily from the Vinaya Pitaka (specifically the Cullavagga, in the section on duties for forest-dwelling monks, Āraññikavatta), along with supporting mentions in the Sutta Pitaka.
Here is how the requirement came about, what the Buddha specifically instructed, and why.
1. The Vinaya Origin Story (Cullavagga)
In the monastic code, the rule was established after a group of forest-dwelling monks encountered bandits in the wilderness:
The Incident: Bandits traveling through the forest approached the monks and asked them for drinking water, fire, the current cardinal directions (disā), and the positions of the lunar constellations/asterisms (nakkhattapadāni). Because the monks lived purely in meditation and lacked basic wilderness skills, they couldn’t answer. The bandits assumed the monks were impostors or thieves themselves and beat them up.
When the Buddha heard about this, he established a set of practical standards (vatta) for any monk living out under the stars or deep in the wilderness:
The Rule:
- “A forest-dwelling monk should learn the lunar mansions (nakkhattapadāni uggahetabbāni)—either all of them or in part.”
- “He should be skilled in knowing the cardinal directions (disākusalena bhavitabbaṁ).”
- He was also required to keep fire-generating sticks, store drinking water, and carry basic survival gear.
2. Why Did Wilderness Monks Need Star Knowledge?
The term used in Pali is nakkhatta (Sanskrit: Nakshatra), which refers to the 27 lunar mansions or star clusters along the moon’s path across the night sky.
The Buddha prescribed this not for astrology or fortune-telling (which monks were strictly forbidden from practicing), but for three purely practical survival and monastic needs:
- Navigation & Wayfinding: Knowing how to orient oneself by the stars prevented monks from becoming lost in dense jungle or open wilderness.
- Timekeeping & Calendar: Without clocks, watching the moon’s movement through the nakkhattas allowed monks to anticipate the Uposatha (full/new moon observance days) and track seasonal changes.
- Assisting Travelers: Forest monks were expected to be helpful guides to lost travelers, foresters, or pilgrims wandering through the wilderness.
3. A Related Sutta Reference: Warding Off Sleepiness
In the Pacalāyana Sutta (Anguttara Nikaya 7.61), Venerable Mahāmoggallāna was meditating in the forest under the open sky and falling asleep. The Buddha appeared to him and offered a sequence of practical techniques to combat drowsiness.
One of those suggestions was to step outside, look up, and survey the night sky:
“If by doing this you don’t shake off your drowsiness, then look up and examine the major stars and constellations…” — AN 7.61
