Answer: (C) Lokayata and Kapalika

The six orthodox systems (Shad Darshana) of Indian Philosophy are:

(1) Sankhya and

(2) Yoga (paired),

(3) Nyaya and

(4) Vaisheshika (paired),

(5) Purva Mimamsa and

(6) Uttara Mimamsa/Vedanta (paired).

They are called 'orthodox' (astika) because they accept the authority of the Vedas.

Lokayata (Charvaka) is a HETERODOX (nastika) materialist philosophy that rejects the Vedas, the soul, and afterlife.

It believes only in direct perception.

Kapalika is NOT a philosophical system at all — it's a Shaivite tantric sect known for extreme ascetic practices.

So Lokayata + Kapalika is the pair that does NOT belong to the six systems.

Memorise the three pairs:

  • Sankhya-Yoga
  • Nyaya-Vaisheshika
  • Mimamsa-Vedanta.

(Ref: R.S. Sharma, Ancient India)

Why this was asked

The six orthodox systems of Indian philosophy are organized into three complementary pairs: Sankhya-Yoga, Nyaya-Vaisheshika, and Mimamsa-Vedanta.

Lokayata (Charvaka) is a heterodox materialist school that rejects Vedic authority, while Kapalika is not a philosophical system but a tantric Shaivite sect with extreme practices.

Six Orthodox Systems (Shad Darshana)

Art And Culture six systems Mimamsa Vedanta Nyaya Vaisheshika Sankhya Yoga

Six Orthodox Systems (Shad Darshana): The Astika Schools of Indian Philosophy

Must know

Shad Darshana are the six orthodox systems that accept Vedic authority

Three paired systems: Sankhya-Yoga, Nyaya-Vaisheshika, Mimamsa-Vedanta

Called astika (orthodox) because they accept the Vedas as valid source of knowledge

Good to know

Each pair complements the other - theoretical and practical aspects

What Makes Them Orthodox

Shad Darshana means 'six viewpoints' - these are the six orthodox (astika) schools of Indian philosophy. They are considered orthodox because they accept the Vedas as a valid source of knowledge, even if they interpret them differently.

The Six Systems in Three Pairs

Pair

System 1

System 2

Focus

Key Contribution

First Pair

Sankhya

Yoga

Dualism & Practice

Theory of 25 principles + meditation methods

Second Pair

Nyaya

Vaisheshika

Logic & Atomism

Logical reasoning + atomic theory

Third Pair

Purva Mimamsa

Uttara Mimamsa (Vedanta)

Ritual & Knowledge

Vedic rituals + ultimate reality

Key Characteristics

Sankhya-Yoga: Sankhya provides the theoretical framework (dualism of Purusha and Prakriti), Yoga provides the practical path

Nyaya-Vaisheshika: Nyaya focuses on logic and epistemology, Vaisheshika on atomic theory and categories

Mimamsa-Vedanta: Purva Mimamsa emphasizes ritual action (karma), Uttara Mimamsa focuses on knowledge (jnana)

All six accept moksha (liberation) as the ultimate goal of human life

They form complementary pairs rather than competing systems

Connection to the Question

UPSC tested whether students could identify which pair does NOT belong to the Shad Darshana. Lokayata (Charvaka) is heterodox and rejects Vedas, while Kapalika is not even a philosophical system but a tantric sect.

Exam traps

Trap: Confusing Lokayata (heterodox philosophy) with orthodox systems

Trap: Thinking Kapalika is a philosophical school when it's actually a Shaivite tantric sect

Trap: Not knowing the exact three pairs - questions often mix correct and incorrect pairings

Memory aid: SAM-NY-MV = SAnkhya-Moga, NYaya-Vaisheshika, Mimamsa-Vedanta

Heterodox Schools (Nastika)

Art And Culture Lokayata

Heterodox Schools (Nastika): Philosophy Beyond Vedic Authority

Must know

Nastika schools reject Vedic authority as source of valid knowledge

Main heterodox schools: Buddhism, Jainism, Lokayata (Charvaka)

Lokayata is pure materialism - only accepts direct perception as valid knowledge

What Makes Them Heterodox

Nastika means 'those who say no' - these schools reject the Vedas as authoritative scripture. This doesn't make them atheistic necessarily, but they don't accept Vedic revelation as a valid source of knowledge.

Major Heterodox Schools

School

Founder/Key Figure

Core Belief

Attitude to Vedas

Buddhism

Gautama Buddha

Four Noble Truths, Middle Path

Rejects Vedic authority

Jainism

Mahavira (24th Tirthankara)

Ahimsa, Karma, Liberation

Rejects Vedic authority

Lokayata (Charvaka)

Charvaka

Pure materialism, no soul/afterlife

Completely rejects Vedas

Lokayata (Charvaka) Philosophy

Only direct perception (pratyaksha) is valid means of knowledge - rejects inference and testimony

No soul, no afterlife - consciousness emerges from matter and dies with the body

Pleasure is the highest goal - 'eat, drink and be merry' philosophy

Rejects karma theory - no moral consequences carry over to next life

Pure materialism - only four elements (earth, water, fire, air) exist

Exam traps

Trap: Confusing Lokayata with orthodox systems - it's completely materialist and anti-Vedic

Trap: Thinking all nastika schools are atheistic - Buddhism and Jainism have spiritual elements

Memory aid: Lokayata = Loka (world) + ayata (extended) = only this world exists, no afterlife

Tantric Sects and Kapalika

Art And Culture Kapalika

Tantric Sects: Kapalika and Other Extreme Shaivite Practices

Must know

Kapalika is a Shaivite tantric sect, not a philosophical school

Known for extreme ascetic practices including use of human skulls as bowls

Good to know

Sects focus on ritual practices, philosophical schools focus on systematic thought

Sects vs Philosophical Schools

Kapalika is a religious sect, not a philosophical system. While philosophical schools develop systematic theories about reality and knowledge, sects focus on specific ritual practices and worship methods. This is why Kapalika cannot be paired with philosophical systems.

Kapalika Characteristics

Shaivite tantric sect that worships Lord Shiva in his fierce Bhairava form

Extreme ascetic practices - practitioners lived in cremation grounds and used human skulls

Kapala means skull - hence the name Kapalika (skull-bearers)

Believed that extreme practices could lead to supernatural powers (siddhis)

Declined by medieval period due to social opposition to extreme practices

Religious Sects vs Philosophical Schools

Aspect

Philosophical Schools

Religious Sects

Primary Focus

Systematic theory and logic

Ritual practices and worship

Goal

Understanding reality through reasoning

Spiritual experience through practice

Examples

Sankhya, Nyaya, Vedanta

Kapalika, Pasupata, Lingayat

Method

Philosophical discourse and debate

Specific rituals and observances

Exam traps

Trap: Treating Kapalika as a philosophical school when it's a tantric sect

Key distinction: Sects = ritual practices, Schools = systematic philosophy

UPSC pattern: Often mixes genuine philosophical schools with sects or movements to create wrong options
