What are the lower realms?
The lower realms are the three unfavorable domains of rebirth in Buddhist cosmology: the hell realm (naraka), the hungry-ghost realm (preta), and the animal realm (tiryak). In the teaching on the six realms of samsara, they sit below the realms of gods, demi-gods, and humans. The upper three are marked by greater ease and more capacity for virtue. The lower three are marked by the dominance of suffering and the near-absence of conditions favourable to practice. The driving force for rebirth in these states is karma rooted in the three root poisons: hatred, craving, and delusion.
Lower realms vs hell, purgatory, and bardo
The lower realms are often confused with similar ideas in other traditions. The Christian hell is understood, in most of its interpretations, as a permanent or indefinitely lasting state. The lower realms in Buddhism are strictly temporary: held as long as the driving karma sustains them, then exhausted. Catholic purgatory is a transitional state on the way to a final destination; the lower realms are one destination on a continuous wheel, not a waystation toward something permanent. The Tibetan Buddhist bardo is the interval between death and rebirth. The lower realms are the realms one can be born into from the bardo, not the interval itself.
The three lower realms
The naraka realm is the domain of acute and prolonged suffering. Buddhist texts describe multiple narakas, both hot and cold varieties, each arising from specific harmful actions such as killing, sustained deception, or the destruction of others' capacity for practice. The preta realm is the domain of hungry ghosts: beings depicted with enormous stomachs and vanishingly small mouths, unable to satisfy the craving that drove them there. The image is understood in the tradition as a picture of insatiable wanting. The tiryak realm is the animal realm. Animals are described in the texts as dominated by instinct, preying and being preyed upon, and lacking the mental freedom needed for deliberate virtue. Of the three, naraka is considered the most painful. The animal realm, with its more ordinary suffering, is the least.
The six realms and the wheel of life
The six realms together make up the Bhavacakra, the wheel of existence, which appears in Tibetan iconography as a great wheel held by Yama, the lord of death. At its centre sit the three root poisons: a pig representing delusion, a snake representing hatred, and a rooster representing greed. Each bites the tail of the one ahead, showing how the poisons feed each other in a cycle. The Theravāda and Mahāyāna and Vajrayāna traditions agree on the broad structure, though the Pāli texts sometimes count five realms, merging gods and demi-gods into one. The lower three realms serve a specific doctrinal function. They are the baseline from which the precious human rebirth rescues a practitioner. In Tibetan practice, reflecting on the likelihood of lower-realm rebirth is the first of the four foundational contemplations, offered as a prompt to use the present human lifetime well.
Psychological readings
Chögyam Trungpa Rinpoche taught the six realms as states of mind as well as cosmological destinations. On this reading, the hell realm is the claustrophobic world of unrelenting aggression, where everything appears as enemy or threat. The hungry-ghost realm is the state of chronic craving: the relentless seeking of satisfaction that only deepens the want. The animal realm is comfort-seeking and territorial habit, the mind that refuses to look up from its immediate concerns. These states are not only possible future rebirths. They are recognisable patterns of mind that arise and pass in waking life. The cosmological and psychological readings are not in conflict in the tradition; both are held simultaneously.
Where to encounter the lower realms in the index
Chögyam Trungpa Rinpoche's *Cutting Through Spiritual Materialism* addresses the six realms directly as both cosmological fact and ego-pattern typology. Pema Chödrön's *When Things Fall Apart* works closely with the hungry-ghost impulse: the mind that turns groundlessness into a problem to be solved by consuming something. Her course on awakening compassion extends the same insight into practice: tonglen directly meets the lower-realm states as both present experience and as the target of compassion sent outward. Tara Brach and Jack Kornfield's Power of Awareness approaches the same territory from a vipassanā angle: the core purpose of mindfulness practice is recognising the mental states that generate suffering and stepping out of their momentum.
