Chapter 12, “Buildings, Paintings and Books,” highlights the remarkable achievements of ancient India in the fields of architecture, art, science, and literature.

Ancient Indian metallurgists were highly advanced. While the Harappans belonged to the Bronze Age, their successors entered the Iron Age, producing forged, wrought, and cast iron.

  • The Iron Pillar: Located at Mehrauli, Delhi, this 7.2-meter-high pillar weighs over 3 tonnes.
  • Historical Significance: It was made about 1500 years ago during the time of a ruler named Chandra, likely of the Gupta dynasty.
  • Scientific Wonder: Despite being over 15 centuries old, the pillar has not rusted.

The period saw the construction of grand religious structures made of brick and stone.

The word stupa means “mound”.

  • Common Features: Most stupas have a small box at the center—a relic casket—containing the bodily remains of the Buddha or his followers (such as teeth or ashes) or items they used.
  • Structure: This casket was covered with earth, followed by layers of mud or baked brick, and often topped with carved stone slabs.
  • Pradakshina Patha: A circular path for devotees to walk around the stupa in a clockwise direction.
  • The Great Stupa at Sanchi: Built over centuries, with a brick mound likely dating to the time of Ashoka and railings/gateways added by later rulers.
  • Garbhagriha: The “womb chamber” where the image of the chief deity (such as Vishnu, Shiva, or Durga) was placed.
  • Shikhara: A tower built on top of the garbhagriha to signify its sacred status.
  • Mandapa: A hall where people could assemble.
  • Monoliths: Temples at Mahabalipuram were carved out of a single, massive piece of stone.

The caves at Ajanta (Maharashtra) contain world-famous monasteries decorated with exquisite paintings.

  • Technique: Because the caves were dark, artists painted by the light of torches.
  • Materials: Vivid colors were made from plants and minerals, surviving for 1500 years.

This era was a golden age for long compositions about heroic men, women, and gods.

  • Tamil Epics:
    • Silappadikaram: Composed by Ilango around 1800 years ago, telling the story of Kovalan, Madhavi, and Kannagi.
    • Manimekalai: Composed by Sattanar around 1400 years ago.
  • Sanskrit Literature: Kalidasa wrote famous works like the Meghaduta.
  • Puranas: Literally meaning “old,” these contain stories of gods/goddesses and were written in simple Sanskrit so they could be heard by everyone, including women and shudras.
  • Sanskrit Epics: The Mahabharata and Ramayana were written down about 1500 years ago. Vyasa is the credited compiler of the Mahabharata, while Valmiki is recognized as the author of the Sanskrit Ramayana.

Significant scientific progress was recorded in Sanskrit texts.

  • Aryabhata: A mathematician and astronomer who wrote the Aryabhatiyam. He correctly stated that day and night are caused by the rotation of the earth on its axis and provided a scientific explanation for eclipses.
  • Zero and Numerals: Indian mathematicians invented a special symbol for zero, a system later adapted by Arabs and spread to Europe.
  • Ayurveda: A health science developed in ancient India. Key texts include the Charak Samhita (medicine) by Charaka and the Susruta Samhita (surgical procedures) by Sushruta.

These articles ensure that religion in India is not just a private affair but a protected communal activity, while simultaneously maintaining a “wall of separation” to prevent the State from becoming a theocracy.

While Article 25 protects the individual, Article 26 protects the rights of “Religious Denominations” or sections thereof. It guarantees the right to organize and manage their own affairs.

Every religious denomination has the right:

  1. Establish and Maintain Institutions: For religious and charitable purposes.
  2. Manage Own Affairs: Specifically in “matters of religion.”
  3. Own and Acquire Property: Both movable (money, vehicles) and immovable (land, buildings).
  4. Administer Property: In accordance with law.

The Supreme Court (in the Shirur Mutt case) laid down three conditions for a group to be a “denomination”:

  • It must be a collection of individuals who have a system of beliefs (common faith).
  • It must have a common organization.
  • It must be designated by a distinctive name.
  • Example: The Ramakrishna Mission and Anand Marg are denominations within Hinduism.

Restriction: Like Article 25, these rights are subject to Public Order, Morality, and Health, but notably not subject to other Fundamental Rights (unlike Art 25).

Article 27 is a pillar of Indian Secularism. It prevents the State from using public money (collected via taxes) to favor one religion over another.

  • The State cannot compel any person to pay any taxes, the proceeds of which are specifically used for the promotion or maintenance of any particular religion or religious denomination.
  • The Logic: If the State uses tax money to support only one religion, it violates the principle of secularism. However, if the State supports all religions equally, it may not violate this article.

The Supreme Court has made a vital distinction here:

  • Tax: Prohibited if used for a specific religion.
  • Fee: Permitted. The State can charge a “fee” from pilgrims (like at the Vaishno Devi shrine or Haj) to provide secular services like sanitation, security, and health. A fee is a payment for a service, not a promotion of the faith.

This article deals with the “Secular Character” of educational institutions. It regulates whether religious instruction can be provided in schools and colleges.

The legality of religious instruction depends on the type of institution:

Type of InstitutionReligious Instruction
Wholly maintained by State fundsCompletely Prohibited.
Administered by State but established under Trust/EndowmentPermitted (e.g., a school founded by a religious trust).
Recognized by the StatePermitted on voluntary basis.
Receiving aid out of State fundsPermitted on voluntary basis.

In institutions where religious instruction is permitted (types 3 and 4), no person can be forced to participate.

  • If the student is a minor, the consent of the guardian is required.
  • This ensures that the State does not use education as a tool for religious proselytization.
ArticleNature of RightKey Limitation
26Collective (For groups/sects)Public Order, Morality, Health.
27Fiscal (Tax protection)Distinguishes between Tax (No) and Fee (Yes).
28Educational (Schools/Colleges)Prohibits forced religious instruction in State-funded schools.

🕌 Articles 26, 27 & 28

🏛️ Art 26: Collective Rights
Protects Religious Denominations. They have the right to establish institutions, manage their own religious affairs, and own/administer property according to law.
🔍 What is a Denomination?
Per the Shirur Mutt case, a group needs: 1. A Common Faith, 2. A common organization, and 3. A Distinctive Name (e.g., Ramakrishna Mission).
💰 Art 27: Secular Taxation
The State cannot compel any person to pay Taxes specifically for the promotion of any particular religion. This maintains the State’s Religious Neutrality.
⚖️ Tax vs. Fee
While Taxes (general revenue) are prohibited for religion, the State can charge Fees from pilgrims to provide secular services like security and sanitation.
🏫 Art 28: Religious Instruction
Religious teaching is Prohibited in schools wholly funded by the State. In aided or recognized schools, it is permitted only on a Voluntary Basis.
✍️ Consent & Minors
No person can be forced to attend religious instruction. For Minors, the express consent of the Guardian is mandatory to participate in any religious activities.
Summary Art 26 covers group rights, Art 27 ensures fiscal secularism, and Art 28 maintains the secular character of educational institutions.

Here is a detailed analysis of the The Hindu Editorials for January 14, 2026, categorized by syllabus relevance for UPSC preparation.

Syllabus: GS Paper 2 (International Relations; India and its Neighborhood- Relations; Security Challenges and their Management in Border Areas).

Context: Army Chief General Upendra Dwivedi’s annual press conference highlighting the status of disengagement and the “stable but sensitive” environment along the Line of Actual Control (LAC).

Key Points:

  • Operational Readiness: The Army Chief stated that while disengagement has occurred in specific sectors (Depsang and Demchok), the military remains in a high state of alert to prevent any unilateral change to the status quo.
  • Trust as a Casualty: He emphasized that “trust” has been the biggest casualty since April 2020. Restoring it requires a multi-stage process: Disengagement, De-escalation, and finally, De-modding (management of troops).
  • Infrastructure Parity: India is rapidly constructing border roads, tunnels, and bridges to achieve parity with Chinese infrastructure, ensuring swift troop mobilization if required.

UPSC Relevance: Vital for questions on “Indo-China Relations,” “National Security,” and “Border Infrastructure Development.”

Detailed Analysis:

  • The De-escalation Challenge: The transition from disengagement to de-escalation is complex. It involves moving heavy artillery, tanks, and thousands of troops back to their permanent rear bases—a move China has been hesitant to commit to fully.
  • Buffer Zones and Patrolling: The creation of temporary “no-patrol” buffer zones has successfully prevented physical brawls but has also restricted India’s traditional access to several patrolling points.
  • Strategic Patience: The Army’s stance indicates a shift toward a long-term “wait and watch” policy, where diplomatic engagement is backed by a robust military posture on the ground.

Syllabus: GS Paper 2 (Governance; Important aspects of governance; Social Justice; Role of Judiciary).

Context: Recent Supreme Court observations suggesting that individuals who feed stray dogs could be held financially liable for the victims’ medical expenses in case of dog bites.

Key Points:

  • Legal Responsibility: The Court observed that while feeding animals is an act of compassion, it should not lead to a public nuisance or safety hazard. Feeders may be asked to bear the cost of treatment for victims bitten by the dogs they sustain.
  • Constitutional Balance: The Court is navigating the fine line between the “Right to Life” (Article 21) of citizens and the ethical treatment of animals.
  • ABC Rules Oversight: The primary responsibility for sterilization and vaccination lies with local municipal bodies under the Animal Birth Control (ABC) Rules.

UPSC Relevance: Important for “Judicial Activism,” “Local Self-Government Challenges,” and “Public Health Policy.”

Detailed Analysis:

  • Institutional Failure: The editorial notes that the rise in stray dog attacks is a direct result of the failure of urban local bodies to implement sterilization programs effectively.
  • Social Conflict: The lack of clear guidelines has led to increasing friction between “animal lovers” and “resident welfare associations (RWAs),” requiring the judiciary to step in as an arbiter.
  • Implementation Gaps: For a feeder-liability rule to work, there must be a way to legally define “regular feeding” and link a specific dog to a specific feeder, which remains a logistical challenge.

Syllabus: GS Paper 1 (Modern Indian History; Social Empowerment; Political Philosophies).

Context: An analysis of the historical and political significance of the colour blue, tracing its journey from the indigo fields of Champaran to the Ambedkarite movement.

Key Points:

  • Champaran Satyagraha (1917): The link begins with the struggle of indigo (neel) farmers against British planters, making blue a colour associated with peasant resistance.
  • Ambedkar’s Sky: Dr. B.R. Ambedkar chose blue for the Scheduled Castes Federation flag, representing the sky—universal, vast, and free from the boundaries of caste or religion.
  • Dalit Assertion: Today, the blue scarf and flag are powerful visual symbols of Dalit identity, dignity, and a demand for constitutional rights.

UPSC Relevance: Significant for “Social Reform Movements,” “Political Sociology,” and “History of the Freedom Struggle.”

Detailed Analysis:

  • A Secular Identity: Unlike saffron or green, which are often associated with specific religions, blue was selected as a “neutral” colour that embodies secularism and constitutionalism.
  • Visual Solidarity: The colour serves as a unifying thread for the marginalized across different languages and regions in India, creating a pan-Indian identity centered on empowerment.
  • From Oppression to Power: The transition of blue from a symbol of colonial exploitation (Indigo) to a symbol of political power (Ambedkarite movement) reflects the changing social fabric of India.

Syllabus: GS Paper 3 (Environment and Ecology; Disaster Management).

Context: A major forest fire in the Valley of Flowers (UNESCO World Heritage Site) has persisted for five days, leading the state to seek help from the Indian Air Force (IAF).

Key Points:

  • Ecological Loss: The Valley is home to 600 varieties of exotic flowers and rare medicinal herbs that are currently at risk.
  • IAF Intervention: The IAF is deploying helicopters with “Bambi Buckets” to lift water from high-altitude reservoirs to douse fires in steep, inaccessible terrains.
  • Climate Drivers: A severe lack of winter snowfall and an unusually dry season have turned the forest floor into a tinderbox.

UPSC Relevance: Essential for “Conservation of Biodiversity,” “Disaster Management Mechanisms,” and “Himalayan Ecology.”

Detailed Analysis:

  • The Policy Gap: Forest fire management in India is often reactive. The editorial suggests a need for a “National Forest Fire Policy” that focuses on community-led “Van Panchayats” and satellite-based early warning systems.
  • Invasive Species: The proliferation of chir pine (highly flammable) over broad-leaved trees like oak has made the Himalayan forests more susceptible to uncontrollable blazes.

Syllabus: GS Paper 3 (Internal Security; Cyber Security; Role of technology in policing).

Context: The Union Home Ministry has constituted a high-level committee to tackle the “Digital Arrest” scam, where fraudsters pose as law enforcement to extort money.

Key Points:

  • Scam Mechanism: Criminals use video calls to pose as CBI or ED officials, telling victims they are under “digital arrest” and cannot leave their homes or disconnect until they pay a fine.
  • Inter-Agency Panel: The panel includes the Indian Cyber Crime Coordination Centre (I4C), the RBI, and the Department of Telecommunications (DoT) to block fraudulent SIMs and freeze bank accounts in real-time.
  • Verification Protocols: The committee is working on a system where citizens can verify the identity of a calling officer through a government portal.

UPSC Relevance: Key for “Cyber Security Challenges,” “Police Reforms,” and “Financial Fraud Prevention.”

Detailed Analysis:

  • Cross-Border Links: Many of these scams originate from “cyber-slave” hubs in Southeast Asia (Cambodia, Myanmar), requiring international cooperation via Interpol.
  • The Psychological Element: Fraudsters exploit the fear and respect the common citizen has for law enforcement. The editorial emphasizes that public awareness is the first line of defense; law enforcement never conducts interrogations via video calls.

For today’s mapping notes, we will focus on India’s Major Tribes, Agricultural Belts, and International Boundaries and Strategic Lines.

India has a diverse tribal population, with communities residing in specific geographical zones based on forest and hilly terrains.

  • North and North-East India:
    • Bhotias and Gujjars: Found in the Himalayan regions of Uttarakhand and Himachal Pradesh.
    • Garo, Khasi, and Jaintia: Primarily residing in the hills of Meghalaya.
    • Nagas: Located across the state of Nagaland and parts of Manipur.
  • Central India:
    • Gonds: One of the largest tribal groups, found across Madhya Pradesh, Chhattisgarh, and Maharashtra.
    • Bhils: Predominantly found in Rajasthan, Gujarat, and Madhya Pradesh.
    • Santhals: Mainly concentrated in Jharkhand, West Bengal, and Odisha.
  • South India:
    • Todas: Unique community living in the Nilgiri Hills of Tamil Nadu.
    • Chenchus: Primarily found in the Nallamala Hills of Andhra Pradesh and Telangana.

The distribution of crops in India is determined by soil types, rainfall, and temperature.
