1.1     Introduction to Indian Knowledge Systems (IKS)

Indian Knowledge Systems (IKS) refer to the holistic, multidimensional knowledge traditions of India developed over thousands of years.

Key Features

• Holistic worldview (सर्वांगिण दृष्टिकोण)
• Harmony with nature (निसर्गसंगती)
• Integration of spiritual & material knowledge
• Ethical foundation (नीतिमूलक दृष्टिकोन)
• Experiential + Logical knowledge (अनुभव + तर्क)
• Interdisciplinary approach

Sources of IKS

• Vedas, Upanishads, Darshanas (दर्शन)
• Ayurveda, Yoga, Vyakarana, Arthashastra
• Mathematics, Astronomy
• Fine arts, Architecture, Ecology

 

1.2 Defining Indian Knowledge System (IKS) and Its Components

Definition: IKS is a comprehensive system of knowledge rooted in Indian philosophy, science, culture, and practices that aims at the well-being of individual and society.

Main Components of IKS

1. Philosophy (दर्शनशास्त्र) : Indian philosophical schools explaining reality, knowledge, mind, and liberation. Includes Nyaya, Vaisheshika, Sankhya, Yoga, Mimamsa, Vedanta.

2. Language & Grammar (भाषा व व्याकरण): Scientific analysis of language; Panini’s Ashtadhyayi is a foundational text. Covers linguistics, logic of meaning, communication.

3. Health Sciences (आयुर्वेद व योग): Ayurveda – holistic medical system based on doṣa–dhātu–mala theory. Yoga – discipline of body-mind harmonization through ashtanga yoga.

4. Mathematics & Astronomy (गणित व ज्योतिष/खगोलशास्त्र): Developed by Aryabhata, Brahmagupta, Bhaskara. Includes algebra, trigonometry, geometry, calendar science, planetary motion.

5. Polity, Economy & Governance (अर्थशास्त्र व राज्यशास्त्र): Based on Kautilya’s Arthashastra, Manusmriti, and other texts. Covers administration, taxation, diplomacy, trade systems.

6. Arts, Music, and Aesthetics (कला, संगीत, नाट्य): Guided by Natyashastra. Includes dance, drama, sculpture, architecture, iconography (प्रतिमा-शास्त्र).

7. Environmental Knowledge (पर्यावरण व पंचमहाभूत सिद्धांत): Understanding of nature through five elements (पंचमहाभूत)— earth, water, fire, air, ether. Focus on ecological balance and sustainable living.

8. Architecture & Engineering (वास्तुशास्त्र): Indian architectural principles: Vastu Purusha Mandala, temple design, town planning, water systems.

9. Ethics & Social Values (धर्म, नीतिशास्त्र): Guiding principles for righteous living, social order, duties, and harmony.

10. Knowledge Systems & Epistemology (प्रमाणशास्त्र): Ways of obtaining valid knowledge—Perception (प्रत्यक्ष), Inference (अनुमान), Verbal testimony (शब्द) etc.

 

1.3     Contributions of Aryabhata & Brahmagupta; Buddhist Logico-Epistemology

Aryabhata (476 CE)

• Author of Aryabhatiya.
• Correct approximation of π.
• Explained day–night by Earth’s rotation.
• Scientific explanation of eclipses.
• Developed trigonometric functions (ज्या – sine).
• Introduced algebraic ideas.

Brahmagupta (598 CE)

• Author of Brahmasphutasiddhanta.
• Zero (शून्य) defined mathematically.
• Rules for operations on negative numbers.
• Solutions for quadratic equations.
• Early ideas of gravitational attraction.

Buddhist Logico-Epistemology (बौद्ध तर्क-प्रमाणशास्त्र)

• Developed by Dignāga and Dharmakīrti.
• Two valid means of knowledge:

1.     Perception (प्रत्यक्ष)

2.     Inference (अनुमान)

• Doctrine of Momentariness (क्षणिकवाद)
• Dependent origination (प्रतीत्यसमुत्पाद) explains causal relations.

 

1.4     The Knowledge Triangle

The Knowledge Triangle (ज्ञानत्रिकोण) – Brief

In Indian Knowledge Systems (IKS), knowledge arises from the interaction of three essential components. These three form the Knowledge Triangle.

1. Knower (ज्ञाता / Jñātā): The observer, the person who seeks or holds knowledge. Represents the mind, senses, awareness, and consciousness.

2. Known / Knowable (ज्ञेय / Jñeya): The object, fact, or truth that is to be known. Anything that becomes the subject of inquiry—material or abstract.

3. Knowledge (ज्ञान / Pramā): The valid cognition generated when the knower understands the known correctly.Produced through valid means of knowledge (प्रमाण / Pramāṇa).

 

1.5     Prameya – A Vaiśeṣika Approach to Physical Reality

In Vaiśeṣika Darshana (वैशेषिक दर्शन), Prameya (प्रमेय) means “objects of valid knowledge”—things that can be known or studied.

Vaiśeṣika explains physical reality through a set of fundamental categories known as Padārthas (पदार्थ). These categories describe what exists and how it behaves.

The Main Vaiśeṣika Prameyas (Objects of Knowledge):

1.     Dravya (द्रव्य – Substance): Basic building blocks of reality. Includes 9 substances: Earth, Water, Fire, Air, Ether, Time, Space, Self, Mind.

2.     Guṇa (गुण – Qualities): Attributes of substances like color, taste, smell, number, shape.

3.     Karma (कर्म – Action): Movements or actions that cause change, conjunction (संयोग) or disjunction (वियोग).

4.     Sāmānya (सामान्य – Universal): Common properties shared by many objects.

5.     Viśeṣa (विशेष – Particularity): Unique characteristics that distinguish individual entities.

6.     Samavāya (समवाय – Inherence): Permanent, inseparable relationship between two entities
(e.g., color residing in an object).

7.     Abhāva (अभाव – Non-existence): Recognized later as a separate category to explain absence.

 

1.6 Dravyas – Constituents of Physical Reality

In Vaiśeṣika philosophy (वैशेषिक दर्शन), Dravya (द्रव्य) means substance, the basic building block of the universe.

Vaiśeṣika identifies nine (9) dravyas that make up all physical and non-physical reality.

The Nine Dravyas (नवद्रव्ये):

1. Earth (पृथ्वी): Has smell, solidity. Basis of physical bodies.

2. Water (आप / जल): Has liquidity, taste. Essential for life.

3. Fire (तेज / अग्नि): Heat, light. Transformation and energy.

4. Air (वायु): Touch/pressure. Movement and respiration.

5. Ether (आकाश): Space for sound. Provides room for everything to exist.

6. Time (काल): Governs sequence of events. Past, present, future.

7. Space (दिक् / दिशा): Gives direction and position.

8. Self (आत्मा): Consciousness, experiencer. Individual souls.

9. Mind (मनः): Internal organ enabling attention, thought, memory.

These dravyas are eternal, independent, and form the basis of all experiences and physical reality.

 

1.7     Attributes – Properties of Substances; and Action

Attributes (गुण)

Qualities that reside in substances but cannot exist independently.

Examples:

• Color (वर्ण)
• Taste (रस)
• Smell (गंध)
• Touch (स्पर्श)
• Number, Size, Distance etc.

Action (कर्म)

Action is the motion or activity in a substance.

Actions cause:

• Conjunction (संयोग) – coming together
• Disjunction (वियोग) – moving apart

Karma is central to explaining change in the physical world.

 

1.8     sāmānya, viśeṣa, samavāya

These three are important categories (पदार्थ) in Vaiśeṣika philosophy, used to explain how objects are classified, distinguished, and related.

1. sāmānya (सामान्य – Universal)

Meaning: The common property shared by many objects.
It helps in grouping things together. Example: “Cowness” (गोत्व) present in all cows. “Humanity” (मानवत्व) present in all human beings.

Purpose: Shows similarity or general class nature.

 

2. viśeṣa (विशेष – Particularity)

Meaning: The unique, distinguishing feature of an object.
It helps in identifying something as a separate individual. Example: Each atom (paramāṇu – परमाणु) has its own unique viśeṣa. Each soul (आत्मा) is distinct because of viśeṣa.

Purpose: Explains individual difference.

 

3. samavāya (समवाय – Inherence)

Meaning: A permanent, inseparable relationship between two things.
They cannot exist apart from each other. Examples: Threads in cloth (नस-तंतू आणि कापड). Quality (गुण) inheres in substance (द्रव्य). Parts inhering in whole.

Purpose: Explains how things stay together in a stable way.

 

1.9     Pramāṇa – The Means of Valid Knowledge

Pramāṇa (प्रमाण) = means through which valid knowledge (प्रमा) is obtained.

Commonly accepted pramāṇas:

1.     Perception (प्रत्यक्ष) – direct sense knowledge

2.     Inference (अनुमान) – logical reasoning

3.     Comparison (उपमान)

4.     Verbal Testimony (शब्द) – reliable authority

Some systems add:

• Arthāpatti (अर्थापत्ति – postulation)
• Anupalabdhi (अनुपलब्धि – non-perception)

 

1.10   Saṁśaya – Ambiguities in Existing Knowledge

Saṁśaya (संशय) means doubt or ambiguity when knowledge is unclear.

Reasons for Doubt

• Incomplete perception
• Conflicting signs
• Unclear sensory input
• Lack of prior knowledge

Example: Seeing a distant unclear shape → “Is it a man or a tree?” (माणूस की झाड?)

Pramāṇas are used to resolve saṁśaya.
