Short Summary of Dissertation

By Dr Anindita Roy, PDGCI, IGNCA

# 1: RESEARCH OVERVIEW

Title

Sacred Geometry: Concepts, Symbolism, and Its Presence in Indian Architectural and Ritual Traditions

Abstract

• Sacred geometry is a modern interpretive framework (19th-20th century) - NOT found in classical Indian texts
• Examines how geometric principles serve religious, ritual, and cosmological purposes
• Bridges gap between exaggerated popular claims and fragmented scholarly work
• Uses qualitative, interpretative methodology with purposive case studies
• Analyzes: Vedic fire altar geometry, Sri Yantra, Vastu Purusha Mandala, and four temples

Introduction - Key Points

• "Sacred geometry" is an umbrella term for geometric patterns in religious contexts
• Not a classical Indian term - does not appear in Vedic, Puranic, or Shastric texts
• In India, geometry is integrated into silpa, vastu, yajna, and tantra practices
• Geometry becomes "sacred" through its association with ritual purpose and cosmological representation

# 2: OBJECTIVES

Research Objectives

1.   Clarify the concept of sacred geometry as it applies to Indian traditions

2.   Identify and examine primary textual sources documenting geometric knowledge

3.   Analyze geometric principles in Vedic altar construction (Sulba Sutras)

4.   Examine structure and symbolism of mandalas and yantras (particularly Sri Yantra)

5.   Investigate geometric principles in Indian temple architecture (Vastu Purusha Mandala, proportional systems)

6.   Synthesize findings into a coherent understanding across traditions

7.   Consider implications for design education and practice

Primary Research Question

How do geometric forms function symbolically and structurally within Indian ritual and architectural traditions, and what conceptual frameworks connect geometry with cosmology and sacred space?

 

 # 3: AIM

Aim of the Study

Primary Aim:

To examine the concept of sacred geometry and explore how geometric forms function symbolically and structurally within Indian ritual and architectural traditions

 

Components of the Aim

Component	Focus
Conceptual Examination	Clarify "sacred geometry" in Indian context
Historical Investigation	Trace development from Sulba Sutras to medieval period
Structural Analysis	Examine geometric principles in altars, yantras, temples
Symbolic Interpretation	Understand cosmological meanings embedded in forms
Synthetic Integration	Connect Vedic, Tantric, and architectural traditions
Pedagogical Relevance	Implications for design education

 

Why This Matters

• Traditional geometric wisdom has relevance beyond historical curiosity
• Principles of proportion, harmony, orientation, symbolic representation offer valuable lessons
• Need to approach with scholarly rigor - distinguish attested traditions from later interpretations

 

# 4: METHODOLOGY

Research Philosophy

• Ontology: Constructivist - realities are constructed through cultural practices
• Epistemology: Interpretivist - knowledge through interpretation, not objective measurement
• Justification: Sacred geometry is about meaning, ritual efficacy, cosmology

Research Design - Multiple Case Study

Case	Domain	Primary Source
Vedic Fire Altar Geometry	Ritual	Sulba Sutras (800-200 BCE)
Sri Yantra	Metaphysical/Tantric	Tantric texts
Vastu Purusha Mandala	Architectural	Vastu Shastra texts

 

Data Collection

• Textual Analysis: Close reading of primary translations (Sulba Sutras, Vastu Shastra, Brihat Samhita)
• Visual Analysis: Diagrams, temple plans, photographs
• Literature Review: Academic databases (JSTOR, Project MUSE, Google Scholar)
• Archival Research: Historical photographs, survey drawings

Data Analysis

1.   Within-case analysis (each tradition individually)

2.   Cross-case comparative analysis

3.   Thematic analysis (centre, orientation, precision, numbers)

4.   Synthesis into overarching framework

 

 # 5: LIMITATIONS | Key Limitations

Limitation	Description
Geographic	Limited to Indian subcontinent - North and South traditions
Temporal	Sulba Sutras (800-200 BCE) through medieval (16th c. CE)
Textual	Reliance on translations; uncertain dating; textual variations
Architectural	Many structures modified/damaged; incomplete evidence
Interpretive	Modern frameworks may not capture indigenous understandings
Scope	Only three cases - excludes other relevant traditions
Methodological	Qualitative, interpretive - no new archaeological documentation
Cultural	Inaccessibility of authentic sources; outsider perspective

# 6: RESEARCH GAP FOUND

Grid Continuum: Altar → Yantra/Mandala → Vastu Layouts

The Key Insight: Direct geometric continuum across traditions

The Continuum

Vedic Altar (8×8 grid) → Yantra Bhupura → Vastu Purusha Mandala

Evidence of Continuity

Feature	Vedic Altar	Sri Yantra	Vastu Grid
Grid Size	8×8 squares	8×8 bhupura	8×8 or 9×9
Centre	Central point	Bindu	Brahma-sthana
Gates	Four directions	Four gates	Four entrances
Orientation	Cardinal directions	Cardinal directions	Cardinal directions

 

What This Reveals

• Vedic Altar Grids = geometrically identical to Yantra & Vastu grids
• Bhupura of Sri Yantra = geometrically identical to Sarvatobhadra Vastu grid
• Same grids, same centre, same cardinal orientation
• Resolves separation between Tantric diagram and architectural plan
• Demonstrates sacred geometry is ONE integrated knowledge system

Scalar Progression

Micro (palm-size yantra) → Meso (Vastu grid on site) → Macro (built temple)

# 7: KEY FINDINGS

Major Findings

1. Geometric Precision is Essential

• Incorrect geometry = ineffective ritual, empty yantra, unfit temple
• Sarvatobhadra requires exact measurement for four symmetrical entrances

 2. Square & Circle = Deliberate Choice

• Circle: Cosmic cycles, infinity, unmanifest
• Square: Earthly order, stability, manifestation
• Transformation between them = sacred operation mediating heaven-earth

3. Direct Geometric Continuum

• Altar → Yantra → Vastu Mandala (same grids, centre, orientation)

4. Numbers Encode Cosmic Meaning

• 3,5,7,8,9,108 = cosmic realms, directions, planets, divine attributes

5. Centre is Always Sacred

• Bindu (yantra), Garbhagriha (temple), central point (altar)
• Source of creation - all geometry radiates from and returns to centre

6. Orientation Matters but Alternatives Exist

• Classical: Cardinal alignment required
• Lotus Temple: Radial nine-fold replaces axial while retaining centrality

7. Flexibility within System

• Same mandala = fractal (Khajuraho), stable (Brihadisvara), axial (Akshardham), radial (Lotus Temple)

8. Integrated Knowledge System

• Mathematics + Art + Religion + Craft + Practice
• Transmitted through texts, oral teaching, apprenticeship, ritual

#10: FINAL REFLECTION

The Gift from the Past to the Future

What This Study Revealed

• Ancient builders were mathematicians, cosmologists, and spiritual practitioners
• Geometry was a language - expressing deepest truths about reality, the divine, and human place in cosmos

The Continuum is Real

• From palm-sized yantra to 23-acre campus - same geometric grammar
• Scale changes, meaning does not
• Yantra drawn on copper plate and temple built of granite follow same principles

The Square and Circle Were Never Arbitrary

• Encode oldest observations: day/night cycle, sun's path, earth's stability
• Translate cosmic cycles into built form
• Transform infinite into measurable

For Design Educators

• Design can embody meaning
• Space can be sacred
• Geometry can connect us to something larger than ourselves

For Students of Culture

• Reveals depth and sophistication of Indian civilization
• 2000+ years of thinking about geometry, cosmology, and the divine

For Revitalization

• Knowledge is there - preserved in texts, temples, living traditions
• Must be understood in context, respected in sacredness, transmitted with care

"Sacred geometry in Indian traditions is a gift from the past to the future. Hope that this study contribute, in some small way, to ensuring that gift is received, understood, and passed on."
