Karma, rebirth and Nirvana

In ancient Indian heterodox movements, the Buddhist concept of Karma (Pali: Kamma) transformed the contemporary ritualistic and physical models of causation into a highly psychological framework.

Psychological Volition as Karma

Unlike the Brahmanical view (where Karma primarily meant ritual action) or the Jain view (where Karma was viewed as physical, material particles that literally attached to the soul), Buddhism defined Karma strictly as psychological volition or intention. The Buddha declared in the Anguttara Nikaya:

Any action of body, speech, or mind carries moral weight only if it is driven by deliberate intent. Unintentional actions—such as accidentally stepping on an insect—do not generate karmic bondage, directly contradicting Jain ascetic doctrines.

Classification based on Roots (Mulas)

Karmic actions are categorized based on their underlying psychological motivations, known as the Karmamulas:

• Akusala Karma (Unwholesome Actions): Driven by the three unwholesome roots, also known as the Three Poisons (Trivisha):
  • Raga / Lobha (Greed, Attachment, or Desire)
  • Dvesha / Dosa (Hatred, Enmity, or Ill-will)
  • Moha (Delusion, Ignorance, or Spiritual Blindness)
• Kusala Karma (Wholesome Actions): Driven by positive psychological states: Allobha (generosity), Advesha (loving-kindness), and Amoha (wisdom).

The Mechanics of Rebirth (Punarbhava)

The Buddhist doctrine of rebirth (Punarbhava) presents a significant philosophical paradox: How can rebirth occur if there is no eternal soul (Anatta) to transmigrate?

Continuity of Causal Streams

Buddhism resolves this by replacing the concept of a static soul-vessel with a dynamic, shifting stream of energy. Rebirth is explained as a continuous causal process driven by Pratityasamutpada (Dependent Origination). What moves from one lifetime to the next is not a permanent identity, but a stream of consciousness (Vijnana-sanaatana) carrying accumulated karmic impressions.

The Flame Metaphor

The Milinda Panha uses several metaphors to explain how identity continues without an unchanging substance:

• The Transferred Flame: If a person lights a new candle using the flame of an old candle, the new flame is caused directly by the old one. However, no physical substance traveled from the first candle to the second.
• The Echo: When a sound creates an echo, the echo depends entirely on the original sound, yet the original sound waves did not physically transform into the echo.

Similarly, the final consciousness of a dying person (Marana-satta-vijnana) provides the immediate causal trigger for the ignition of the first spark of consciousness (Pratisandhi-vijnana) in a new womb.

The Gati: Five or Six Realms of Rebirth

The karmic momentum forces the consciousness into one of the realms of the Bhavachakra (Wheel of Life):

1. Devas (Celestial/Heavenly Realm): A state of temporary luxury and pleasure; highly prone to spiritual complacency.
2. Asuras (Titan/Demigod Realm): Driven by jealousy, competitiveness, and constant warfare.
3. Manushya (Human Realm): The most spiritually precious realm. It offers the ideal balance of joy and suffering, providing the conditions necessary to practice the Eightfold Path and achieve Nirvana.
4. Tiryancha (Animal Realm): Driven entirely by basic instincts, fear, and survival needs; lacks the capacity for higher moral reasoning.
5. Preta (Hungry Ghost Realm): Characterized by insatiable desires and psychological torment, symbolized by beings with massive bellies but pinhole mouths.
6. Naraka (Hell Realm): States of intense physical and psychological suffering where negative karma is gradually exhausted.

Nirvana: The Ultimate Cessation

Nirvana (Pali: Nibbana) is the ultimate spiritual goal of Buddhism, marking the complete cessation of suffering (Dukkha), the termination of the cycle of rebirth (Samskara), and absolute liberation from the three poisons.

Etymological Meaning

The term derives from the root meaning “to blow out” or “to extinguish.” It refers to extinguishing the fires of greed, hatred, and delusion, rather than the destruction of the individual personality.

Two Structural Dimensions of Nirvana

The scriptures distinguish between two phases of liberation based on whether the physical body remains present:

Dimension of Nirvana	Technical Term	Operational Mechanism & Description
Nirvana with Remnants	Sopadhishesa-Nirvana / Saupadisesa	Achieved during a person’s lifetime. The fires of desire are extinguished, and the mind enjoys absolute peace and clarity, but the physical body and senses continue to function, experiencing natural heat, cold, and physical aging. Example: Siddhartha Gautama at age 35 under the Bodhi tree.
Nirvana without Remnants	Parinirvana / Anupadhishesa-Nirvana	Achieved at the physical death of an enlightened being (Arhat or Buddha). The five physical and mental aggregates (Pancha-Skandhas) dissolve completely, and the cycle of cause and effect ends permanently. It cannot be described using terms like existence or non-existence.

Comparative Framework across Major Indian Systems

To help navigate these concepts for the civil services examination, the table below contrasts how these three core pillars operate across the major religious and philosophical traditions of ancient India:

Dimension	Buddhist View	Jain View	Orthodox Brahmanical View
Nature of Karma	Strictly a psychological phenomenon based on volition (Cetana).	A physical, material substance (Karmic Varganas) that sticks to the soul.	Ritual actions and moral deeds governed by cosmic order (Rita or Ishvara).
Mechanism of Rebirth	Continuity of a stream of consciousness via cause and effect (Pratityasamutpada).	The physical migration of an eternal soul (Jiva) weighed down by matter.	The transmigration of an immortal, unchanging soul (Atman).
Ultimate Liberation	Nirvana: Extinguishing the illusion of self; unconditioned psychological peace.	Moksha / Siddhashila: The soul rises to the top of the universe, free from all matter.	Moksha: The individual soul (Atman) realizes its identity with the cosmic soul (Brahman).

Analytical Facts Matrix for Prelims

The Kamma-Nirodha

In the Samyutta Nikaya, the Buddha details the path to ending the generation of new karma. He explains that practicing the Noble Eightfold Path acts as “Karma that leads to the destruction of Karma,” transitioning the mind from conditioned existence to the unconditioned reality of Nirvana.

The Concept of the Arhat

An Arhat (literally, “Worthy One”) is a practitioner who has successfully destroyed all mental defilements (Asavas), realized Nirvana with remnants, and guaranteed that they will not undergo another rebirth after the dissolution of their current physical body.

The Unanswered Questions (Avyakata)

When asked by wandering ascetics like Malunkyaputta or Vacchagotta to describe the exact state of a Buddha after death (whether a Buddha exists, does not exist, both, or neither after Parinirvana), the Buddha consistently maintained a noble silence. He asserted that such metaphysical questions are a distraction from the practical work of ending suffering, famously comparing them to a man shot with a poisoned arrow refusing medical treatment until he learns the caste, name, and height of the archer.
