    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Ten Principal Upanishads

    Mains level: Read the attached story

    upanishad

    Central Idea

    • PM Modi presented the US President Joe Biden with a number of gifts, including a first edition print of the book The Ten Principal Upanishads from 1937.

    Ten Principal Upanishads

    • The Ten Principal Upanishads is translated from Sanskrit by Shri Purohit Swami, a scholar of Hindu scripture, and Irish poet WB Yeats.
    • It is considered to be one of the best translations of the Upanishads, some of the most important Hindu religious texts.
    • Written in the mid-1930s, the book was a product of Yeats’ desire to create a translation which is true to the original text while still being accessible for the layperson.

    Two categories of Hindu scriptures

    There are broadly two categories of Hindu sacred texts: Shruti (loosely translated as “the revealed”) and Smriti (“the remembered”).

    [I] Shruti

    • The Shruti category is considered to be the most authoritative and consists of the four Vedas (Rig, Yajur, Sama and Atharva) and accompanying texts.
    • These include Brahmanas (ritual texts), Aranyakas (“forest” or “wilderness” texts), and Upanishads (philosophical texts).

    [II] Smruti

    • The Smruti category of Hindu scriptures is less authoritative – in many ways they are considered to be derived from the first – but more popularly known.
    • These include the great epics of Ramayana and Mahabharata, Dharmashastras, Puranas and all other post-Vedic scriptures.

    What are the Upanishads?

    • The Upanishads, also known as the Vedanta – as they signal the end of the total Veda – speculate about the ontological connection between humanity and the cosmos.
    • They serve as foundational texts in many traditions of Hindu theology and have hence attracted far more attention than the Vedas themselves.
    • Dated to roughly 800-500 BC, the Upanishads discuss concepts such as transmigration, which have today become central to Hindu tradition.
    • Upanishads signify texts that were traditionally transmitted in intimate, teacher-student settings, imparting profound knowledge and spiritual insights.

    (A) Spiritual Essence

    • The Upanishads form the philosophical portion of the Vedic scriptures known as the Vedanta.
    • They explore the metaphysical and mystical aspects of existence, aiming to unravel the nature of reality, the self, and the ultimate truth.

    (B) Origins

    • The Upanishads were composed between 800-500 BC, following the earlier Vedic texts.
    • Various sages, seers, and scholars authored the Upanishads, resulting in a rich diversity of philosophical perspectives.

    (C) Themes and Subjects

    • The Upanishads delve into profound concepts, such as the nature of the self (atman), the ultimate reality (brahman) (NOT Brahmin), and the relationship between the two.
    • They explore metaphysical inquiries, the nature of existence, the concept of karma, the path to liberation (moksha), and the interconnectedness of all beings.

    Key Upanishads and Teachings 

    • While there are over 200 Upanishads, a set of principal Upanishads is considered the most significant and influential.
    • There are ten main (or principal) Upanishads:
    1. Esha
    2. Kena
    3. Katha
    4. Prashna
    5. Mundaka
    6. Mandukya
    7. Taittiriya
    8. Aitareya
    9. Chandogya
    10. Brihadaranyaka

    WB Yeats and his translation of Upanishads

    (A) Who was WB Yeats? 

    • WB Yeats (1865-1939) was born in Ireland and is regarded as one of the most influential figures in modern English literature.
    • He was a key figure in the Irish Literary Revival, which sought to promote Irish culture, folklore, and independence.

    (B) His Interest in the Upanishads

    • Yeats’ interest in Indian culture and philosophy predates his encounter with the Upanishads.
    • In 1885, he met Mohini Chatterjee, a prominent figure in Bengal’s Theosophical circles, who visited Dublin. This meeting sparked Yeats’ early engagement with Indian themes in his poetry.

    (C) Friendship with Rabindranath Tagore:

    • Yeats developed a close friendship with Rabindranath Tagore, the renowned Indian poet, philosopher, and Nobel laureate.
    • In 1912, they met in London, where Tagore introduced Yeats to his translated work, including Gitanjali.

    (D) Introduction to the Upanishads:

    • William Rothenstein, a photographer, sent Yeats the manuscripts of Tagore’s partial translation of the Upanishads.
    • Impressed by their spiritual depth and cultural significance, Yeats became intrigued by the Upanishads’ teachings.
    • Disappointed with the available English translations of the Upanishads, Yeats sought to create a translation that was both true to the original text and accessible to a wider audience.
    • He collaborated with Sanskrit scholar Shri Purohit Swami, who helped him translate the Upanishads with an emphasis on clarity and understanding.

    Back2Basics: Key Verses from Upanishads

    Central Idea

    • The New Collective Quantified Goal (NCQG) has emerged as a significant commitment in global climate financing at the recently-concluded Bonn climate conference in Germany.
    • The conference, which sets the stage for the upcoming Conference of Parties-28 (COP28) in Dubai, has exposed significant gaps in funding for climate action.

    Conference of Parties (COP)

    • The Conference of Parties (COP) is a key international event where countries come together to address the urgent challenges posed by climate change.
    • It is the supreme decision-making body of the United Nations Framework Convention on Climate Change (UNFCCC).
    • The COP brings together representatives from various countries to assess progress, negotiate agreements, and establish international climate policies and commitments.
    • The first COP took place in 1995 in Berlin, Germany, following the adoption of the UNFCCC in 1992.
    • Since then, the COP has been held annually, with each event designated by a specific number (e.g., COP21, COP22) indicating the sequential order.

     

    What is New Collective Quantified Goal (NCQG)?

    • The commitment of $100 billion per year till 2020 to developing nations by developed countries was set at the 2009 COP.
    • The cost estimates for addressing climate change indicate that billions, and possibly trillions, of dollars are required.
    • The 2015 Paris Climate Agreement emphasized the need for a NCQG for climate financing before 2025.
    • The NCGQ aims to account for the needs and priorities of developing nations and has been termed the “most important climate goal.”
    • It should reflect scientific evidence, respond to increased funding requirements for Loss and Damage, and involve developed countries increasing their commitments.

    Need for NCQG

    • Developed countries provided $83.3 billion in 2020 out of the promised $100 billion per year.
    • However, an analysis by Oxfam suggests that these figures may be inflated by as much as 225% due to misleading and dishonest reporting.
    • The $100 billion target set in 2009 lacked clarity in terms of the definition and source of ‘climate finance.’

    Challenges and Concerns

    (A) Accessibility and Sustainability of Climate Finance

    • While the funds for climate finance have increased, they remain largely inaccessible to developing countries.
    • The majority of climate finance comes in the form of loans and equity, burdening developing nations with a debilitating debt crisis.
    • Only around 5% of climate finance is provided as grants, which severely limits the capacity of countries in need.

    (B) Developed Countries’ Perspective

    • Developed countries argue that the NCQG should be seen as a collective goal for all countries.
    • This perspective places the burden of mitigation, adaptation, and loss and damage on developing countries.
    • Experts raise concerns that developing nations may struggle to bear the costs while also ensuring sustainable infrastructure development.
    • Developed countries advocate for mobilizing private-sector investments and loans as a critical component of climate finance.

    Future roadmap

    • A deadline looms for countries to agree on the NCQG before 2024.
    • While there is no official figure yet, estimates suggest that transitioning to a low-carbon economy requires annual investments of $4 trillion to $6 trillion.
    • Some propose setting separate targets or sub-goals for focus areas like mitigation, adaptation, and loss and damage instead of a single aggregate figure.
    • The focus should be on scaling up concessional financing, halting debt creation, and transforming the NCQG into an equitable and people-led transition process.
