Beliefs and teachings in Buddhism: karma, samsara and rebirth

What you'll learn

This topic examines three interconnected Buddhist teachings that explain how actions shape existence across multiple lifetimes. Understanding karma, samsara and rebirth is essential for WJEC GCSE Religious Education because these concepts underpin Buddhist ethics, meditation practices and the path to enlightenment. Exam questions frequently require you to explain how these teachings relate to each other and influence Buddhist behaviour.

Key terms and definitions

Karma — The law of cause and effect; intentional actions (physical, verbal or mental) that create consequences affecting future experiences in this life and future rebirths.

Samsara — The continuous cycle of birth, death and rebirth characterised by suffering (dukkha); the wheel of existence from which Buddhists seek liberation.

Rebirth — The Buddhist understanding that after death, consciousness is reborn into a new life form based on accumulated karma, without a permanent soul transferring between lives.

Nibbana (Nirvana) — The ultimate goal of Buddhism; liberation from samsara achieved by extinguishing craving, hatred and ignorance.

Dukkha — Suffering, unsatisfactoriness or dissatisfaction; the first Noble Truth teaching that existence within samsara involves inevitable suffering.

Anatta (Anatman) — The doctrine of no-self or non-soul; the teaching that there is no permanent, unchanging essence that constitutes a 'self'.

Intention (Cetana) — The mental component that determines the karmic weight of an action; Buddhism teaches that intention is more important than the physical act itself.

Six Realms — The different states of existence within samsara: gods, demi-gods, humans, animals, hungry ghosts and hell beings.

Core concepts

Understanding karma in Buddhism

Karma literally means 'action' in Sanskrit and represents one of Buddhism's most fundamental teachings. Unlike fatalism, karma emphasises personal responsibility — individuals create their own destiny through intentional actions.

The three types of karmic action are:

• Physical karma — bodily actions such as killing, stealing or sexual misconduct
• Verbal karma — speech including lying, harsh words, gossip or divisive talk
• Mental karma — thoughts involving greed, ill-will or wrong views

Buddhism distinguishes between skilful (kusala) and unskilful (akusala) actions:

Skilful actions generate positive karma and lead to favourable rebirths and experiences. These include:

• Generosity (dana)
• Ethical conduct following the Five Precepts
• Meditation and mental cultivation
• Compassion and loving-kindness

Unskilful actions generate negative karma and lead to suffering and unfavourable rebirths. These include:

• The Five Precepts violations: killing, stealing, sexual misconduct, false speech, intoxication
• Actions rooted in the Three Poisons: greed, hatred and delusion

Intention is paramount in determining karmic consequences. The Buddha taught that accidentally stepping on an insect creates minimal negative karma because harmful intention was absent. Conversely, plotting harm even if the plan fails generates significant negative karma because the intention was present.

Karma is not punishment from a deity — Buddhism has no creator god judging actions. Instead, karma operates as a natural moral law, like gravity. Actions naturally bring consequences through cause and effect.

The cycle of samsara

Samsara refers to the continuous cycle of existence that beings undergo through countless lifetimes. The term evokes an image of wandering aimlessly, trapped in repetitive patterns of birth, ageing, sickness, death and rebirth.

Key characteristics of samsara include:

Impermanence (anicca) — Everything within samsara constantly changes. Pleasurable experiences inevitably end, relationships dissolve, youth fades, and life concludes in death. This constant flux prevents lasting satisfaction.

Suffering (dukkha) — The First Noble Truth states that existence within samsara inherently involves suffering. This includes:

• Obvious physical and emotional pain
• The suffering of change (pleasant experiences ending)
• The subtle dissatisfaction underlying even pleasant experiences because they cannot last

Conditionality — Existence within samsara operates through dependent origination (paticca-samuppada), the teaching that phenomena arise dependent on causes and conditions. Birth conditions ageing; ageing conditions death; craving conditions rebirth.

The Wheel of Life (Bhavacakra) visually represents samsara in Tibetan Buddhism, showing:

• The Six Realms of existence in the outer ring
• The Three Poisons (greed, hatred, delusion) at the centre as a pig, snake and cockerel
• The twelve links of dependent origination around the wheel's rim
• Yama, the lord of death, holding the entire wheel, symbolising impermanence

Buddhists view liberation from samsara as the ultimate goal. Remaining trapped in this cycle means experiencing repeated suffering across countless lifetimes, never achieving lasting peace or fulfilment.

Buddhist understanding of rebirth

Rebirth differs fundamentally from reincarnation concepts found in Hinduism. Buddhism denies the existence of a permanent soul (atman) that transmigrates from body to body. Instead, rebirth involves the continuation of consciousness without a fixed self transferring between lives.

The Buddha used analogies to explain rebirth without a soul:

The candle flame analogy — When one candle lights another, the new flame continues from the first but is neither the same flame nor completely different. Similarly, a new life arises conditioned by the previous one without an identical self transferring.

The mango tree analogy — A mango seed grows into a tree that produces fruit containing new seeds. The new seeds arise from the original but are not identical to it. Rebirth works similarly — continuity exists without sameness.

What actually continues at rebirth is the stream of consciousness shaped by karmic accumulations. Think of consciousness as a river continuously flowing — the water at one point connects to what came before and after, yet no individual drop remains the same.

The six realms of existence

Karma determines rebirth into one of six possible realms within samsara:

1. God realm (Deva) — Beings experience extreme pleasure and longevity but remain trapped in samsara. The danger here is complacency; enjoying celestial pleasures, gods neglect spiritual practice and eventually exhaust positive karma, falling to lower realms.

2. Demi-god realm (Asura) — Jealous beings constantly fighting gods for superiority. Their existence involves perpetual competition and dissatisfaction despite possessing power and resources.

3. Human realm — Considered the most favourable rebirth for spiritual progress. Humans experience enough suffering to motivate spiritual practice but sufficient comfort and intelligence to pursue enlightenment. Only humans can achieve nibbana directly.

4. Animal realm — Characterised by ignorance, fear and being dominated by instinct. Animals endure exploitation, predation and lack the capacity for moral reasoning or spiritual development.

5. Hungry ghost realm (Preta) — Beings tormented by insatiable craving. Traditional depictions show creatures with huge stomachs but tiny mouths and necks, symbolising desires that can never be satisfied.

6. Hell realm (Naraka) — Temporary states of intense suffering resulting from severe negative karma. Buddhist hells are not eternal; beings remain until negative karma exhausts, then rebirth elsewhere occurs.

Some Buddhist traditions interpret these realms literally as distinct locations, while others view them as psychological states humans experience. For WJEC GCSE examinations, acknowledge both interpretations exist.

The relationship between karma, samsara and rebirth

These three concepts function interdependently as a system explaining existence and suffering:

1. Actions create karma — Beings perform intentional actions throughout life driven by craving, aversion and ignorance
2. Karma shapes rebirth — Accumulated karma determines the realm, circumstances and characteristics of the next rebirth
3. Rebirth perpetuates samsara — Being reborn means continuing the cycle of existence and experiencing further dukkha
4. Samsara generates more karma — Within each lifetime, beings perform new actions creating additional karma
5. The cycle continues — Without intervention through Buddhist practice, this process repeats endlessly

The Buddha taught that escape from this cycle requires:

• Understanding the Four Noble Truths
• Following the Noble Eightfold Path
• Eliminating the Three Poisons (greed, hatred, delusion)
• Developing wisdom to see reality as it truly is
• Achieving nibbana, which ends rebirth permanently

Implications for Buddhist ethics and practice

Understanding karma, samsara and rebirth profoundly influences Buddhist behaviour:

Ethical motivation — Buddhists strive to perform skilful actions knowing that karma shapes future experiences. This provides immediate motivation for moral behaviour beyond external rules or divine punishment.

Compassion for all beings — Recognising that all sentient beings wander in samsara experiencing suffering cultivates universal compassion (karuna). That animal or person might have been one's mother in a previous life.

Emphasis on intention — Before acting, Buddhists cultivate mindfulness to examine their intentions, ensuring actions arise from wholesome mental states rather than greed, hatred or delusion.

Urgency for spiritual practice — Understanding the endless suffering across countless rebirths motivates serious engagement with meditation and ethical development to achieve liberation.

Rejection of caste systems — Because rebirth is determined by karma rather than birth circumstances, Buddhism rejects social hierarchies based on family background. A person born into poverty might possess excellent karma, while someone born privileged might have negative karma to exhaust.

Worked examples

Example 1: AO1 question (4 marks)

Question: Explain Buddhist beliefs about karma.

Answer: Karma means 'action' and refers to the Buddhist teaching that intentional actions have consequences affecting future experiences. Buddhists believe karma operates through physical, verbal and mental actions. Skilful actions rooted in generosity, compassion and wisdom create positive karma leading to favourable rebirths and pleasant experiences, while unskilful actions rooted in greed, hatred and delusion create negative karma leading to suffering. Intention (cetana) determines the karmic weight of actions — accidentally harming someone creates less negative karma than intentionally causing harm. Karma is a natural moral law rather than punishment from a deity, operating through cause and effect.

Mark scheme notes: This answer would achieve full marks (4/4) by:

• Defining karma accurately
• Identifying physical, verbal and mental types
• Explaining skilful and unskilful karma
• Highlighting the importance of intention
• Clarifying karma as natural law, not divine judgment

Example 2: AO1 question (5 marks)

Question: Describe Buddhist teachings about samsara and rebirth.

Answer: Samsara is the continuous cycle of birth, death and rebirth that Buddhists believe traps beings in endless suffering (dukkha). This cycle is characterised by impermanence (anicca) — nothing lasts permanently — and unsatisfactoriness. Rebirth occurs after death when consciousness continues into a new life form based on accumulated karma, without a permanent soul transferring between lives. This differs from Hindu reincarnation because Buddhism teaches anatta (no-self) — there is no unchanging essence that moves from body to body. Instead, consciousness continues like a candle lighting another candle; the new flame arises from the first but is neither identical nor completely different. Beings are reborn into one of six realms (gods, demi-gods, humans, animals, hungry ghosts, hell beings) depending on their karma. The ultimate Buddhist goal is achieving nibbana, which ends the cycle of rebirth permanently.

Mark scheme notes: This answer would achieve full marks (5/5) by:

• Defining samsara clearly
• Explaining rebirth with reference to karma
• Distinguishing Buddhist rebirth from soul-based reincarnation
• Using the candle analogy appropriately
• Mentioning the six realms
• Connecting to nibbana as liberation

Example 3: AO2 question (15 marks)

Question: "Belief in karma and rebirth is essential to being Buddhist." Discuss this statement showing that you have considered more than one point of view. (You must refer to religion and belief in your answer.)

Approach for a strong answer:

Arguments supporting the statement (6-7 marks worth):

• Karma and rebirth form the foundational framework explaining why ethical behaviour matters — without consequences extending beyond this life, Buddhist ethics lose their urgency
• The Four Noble Truths assume rebirth; the First Noble Truth about dukkha refers to suffering across multiple lifetimes, not just one life
• The Buddha's enlightenment involved remembering past lives and understanding how karma operates, making these teachings central to Buddhism
• Motivation for following the Noble Eightfold Path comes from understanding that unskilful actions perpetuate suffering across rebirths
• Traditional Buddhist texts assume karma and rebirth throughout, suggesting they are essential teachings

Arguments against the statement (6-7 marks worth):

• Secular Buddhists practice Buddhist meditation and ethics while interpreting karma psychologically — actions have consequences in this life through habit formation and social effects
• The Buddha reportedly said his teachings were pragmatic tools for ending suffering, not metaphysical doctrines requiring belief
• Some interpret the six realms as psychological states experienced within a single lifetime rather than literal post-death destinations
• Core Buddhist practices like meditation, mindfulness and compassion remain valuable whether or not rebirth occurs literally
• Modern scientific worldviews make literal rebirth difficult to accept, yet Buddhist practices still benefit practitioners

Conclusion with personal evaluation (2-3 marks worth): Demonstrate balanced thinking by weighing both perspectives. Strong conclusions often note that traditional Buddhism clearly treats karma and rebirth as fundamental teachings, but the pragmatic emphasis on reducing suffering allows meaningful Buddhist practice even for those questioning literal rebirth.

Common mistakes and how to avoid them

Mistake: Confusing Buddhist rebirth with Hindu reincarnation or Christian resurrection. Correction: Buddhism teaches rebirth without a soul (anatta), unlike Hinduism where an eternal atman transfers between bodies. Buddhist rebirth involves consciousness continuing without a fixed self, not a soul moving to a new body or physical resurrection of the same body.

Mistake: Describing karma as fate or predestination, suggesting Buddhists believe everything is predetermined. Correction: Karma emphasises personal agency and responsibility. While past karma influences present circumstances, individuals constantly create new karma through current choices. Buddhism teaches the present moment offers opportunities to perform skilful actions regardless of past karma.

Mistake: Claiming karma operates instantly or mechanically, like a cosmic vending machine. Correction: Karmic consequences manifest across varying timeframes — some actions produce results immediately, others after years, and some only in future rebirths. Karma operates through complex conditions, not simple one-to-one correspondence between actions and outcomes.

Mistake: Writing that Buddhists seek "a better reincarnation" as their ultimate goal. Correction: The ultimate Buddhist goal is nibbana — complete liberation from samsara and the end of rebirth. While accumulating positive karma may lead to favourable rebirths, these remain within suffering-filled samsara. True success means escaping the cycle entirely, not improving one's position within it.

Mistake: Stating that animals or people suffering must have done something to deserve their situation. Correction: While karma explains conditions of rebirth, Buddhism strongly emphasises compassion for all beings regardless of circumstances. Using karma to justify ignoring others' suffering contradicts fundamental Buddhist ethics of loving-kindness (metta) and compassion (karuna). The appropriate Buddhist response to suffering is always compassion and assistance.

Mistake: Writing vaguely about karma as "what goes around comes around" without Buddhist-specific detail. Correction: Use precise Buddhist terminology: explain the three types of karma (physical, verbal, mental), distinguish skilful from unskilful actions, reference the Three Poisons, mention intention (cetana), and connect karma specifically to rebirth within the six realms and the broader cycle of samsara.

Exam technique for beliefs and teachings in Buddhism: karma, samsara and rebirth

AO1 questions (4-5 marks) use command words "describe" or "explain" and require accurate knowledge. Structure answers by:

• Defining key terms precisely using Buddhist terminology
• Providing 4-5 distinct developed points
• Including specific examples or analogies the Buddha used
• Connecting concepts (e.g., explaining how karma determines rebirth within samsara)

AO2 questions (15 marks) use "discuss," "evaluate" or present a statement for consideration. Strong answers:

• Present balanced arguments supporting and challenging the statement (roughly 50-50 split)
• Reference Buddhist teachings explicitly in both perspectives
• Include specific Buddhist terms and concepts throughout
• Develop 4-6 substantial arguments with explanation
• Conclude with personal evaluation weighing the arguments
• Demonstrate understanding that different Buddhist traditions may interpret teachings differently

Mark allocation patterns:

• 1-mark questions: brief definition or single example
• 2-mark questions: two simple points or one developed point
• 4-5 mark questions: 4-5 clear points with accurate terminology
• 15-mark questions: typically 6 marks for arguments supporting, 6 for opposing, 3 for evaluation

Buddhism-specific exam advice:

• Always distinguish Buddhist teachings from other religious perspectives
• Use Pali terms accurately (karma, samsara, nibbana, dukkha, anatta) to demonstrate knowledge
• Reference different Buddhist traditions (Theravada, Mahayana) when relevant
• Connect individual teachings to broader Buddhist framework (Four Noble Truths, Noble Eightfold Path)

Quick revision summary

Karma is the Buddhist law of cause and effect where intentional actions (physical, verbal, mental) create consequences affecting future experiences and rebirths. Samsara is the continuous suffering-filled cycle of birth, death and rebirth from which liberation is sought. Rebirth means consciousness continuing into new life forms based on karma, without a permanent soul transferring. These concepts interconnect: karma determines rebirth; rebirth perpetuates samsara; existence within samsara generates more karma. Understanding these teachings motivates Buddhist ethical behaviour and spiritual practice aimed at achieving nibbana — permanent liberation from the cycle.
