About Namda Craft

SKILL INDIA- Revive Kashmir Namda Art
Kashmir Namda Art
  • It represents the traditional craftsmanship of Kashmir, focusing on the creation of rugs primarily crafted from pure sheep wool.
  • Diverging from conventional rug-making methods, this craft employs the felting technique instead of the typical weaving process, eliminating any involvement of traditional weaving. 
  • The term ‘Namda’ refers to an additional layer crafted above a standard rug, utilizing old blankets in its construction. This versatile craft is designed to suit various climates. 
  • This artistic tradition is thought to have originated in the 11th century, attributed to the inventive Nomadic tribes of the Central Asian steppes.
  • The art form gained popularity in India during the reign of the Mughal emperor Akbar.
    • As per the historical records, Akbar’s exchequer named Nubi personally crafted a felt for Akbar’s horse and adorned it with beautiful designs through embroidery.
    • This exquisite creation earned the name Namda in honour of its skilled manufacturer, Nubi.
  • Artisans specializing in Namda can be found across India, particularly in regions like Kashmir, Himachal Pradesh, and Rajasthan.
    • The craft is predominantly practiced by the Pinjara and Mansuri communities, who are Sama Muslims native to Kutch.

How is Namda made? 

The intricate process involves multiple stages, including carding, border creation, layer formation, soap solution application, rolling, drying, and the meticulous Aari work.

  • Involves carding the wool, a process dedicated to removing impurities and refining the material.
  • Application of soap solution to wash the wool. Application of water to wool gives binding, enhancing the durability and longevity of the Namda.
  • Namda undergoes rolling/pressuring using a tool called Pinjra and drying. In
  • Weaver then attaches the border pattern to the wool to give the foundation.
  • Next comes, initiation of the primary layer, and adding of the colour and pattern of the Namda.
  • Aari work: This stage involves intricate embroidery that imparts a delicate form to the Namda. 

Designing: 

  • Border (Hashi): Borders play a pivotal role in defining the central layout, preventing the Namda from resembling mere fabric.
  • Double Khatamband: Interplay of octagons and squares.
  • Taldaar: Derived from the Kashmiri word ‘Tal,’ meaning 'ceiling,' this motif mirrors the craftsmanship found in ceilings. 
  • Gul-i-akhtab: Reflecting its name, which translates to ‘flower of the sun,’ this Namda motif draws inspiration from the sunflower. 

About Namda Project:

  • Namda Project, an industry-based training program, was introduced in 2021.
  • Namda craft is a rug made of sheep wool through a felting technique instead of the normal weaving process.
  • It is being successfully revived under a Skill India’s Pilot Project as part of the Pradhan Mantri Kaushal Vikas Yojana (PMKVY), with nearly 2,200 candidates from across six districts of the state, receiving training in the dying art form.

Need of the project:

  • Unavailability of adequate raw materials; 
  • Dearth of skilled craftsmen;
  • Infiltration of machine-made carpets;
  • Adulteration and inadequate marketing strategies declined the export by almost 100 per cent and brought the heritage craft to the brink of extinction.

Guru Ravidas

Context: Magh Purnima marks the observance of Sant Guru Ravidas Jayanti (February 24). To commemorate the 647th birth anniversary of Sant Guru Ravidas, the Prime Minister unveiled a statue in Varanasi. 

About Guru Ravidas: 

Sant Guru Ravidas statue in Varanasi
(Ravidas’s statue in Varanasi, Uttar Pradesh) 
  • Born: 1377 CE in Govardhanpur near (Varanasi) Uttar Pradesh.
  • His place of birth is now known as Shri Guru Ravidas Janam Asthan.
  • Revered as a guru in regions such as Punjab, Rajasthan, Maharashtra, and Madhya Pradesh. 

Early life:

  • Parents: Mata Kalsi and Santokh Das, belonged to an untouchable caste and were engaged in leatherworking.
  • At the age of 12, he married Lona Devi, and together they had a son named Vijay Dass.
  • Ravidas redirected his focus towards spiritual pursuits along the banks of the Ganga. 
  • Took extensive pilgrimage travels to Andhra Pradesh, Maharashtra, Gujarat, Rajasthan, and the Himalayas.
  • He became a disciple of the bhakti saint-poet Ramananda.
  • Contributions to Bhakti movement: 
  • He adhered to the Nirguna sampradaya and rejected the Saguna form of Bhakti. 

Historians of religion classify bhakti traditions into two broad categories:

  1. Saguna (with attributes): Focused on the worship of specific deities such as Shiva, Vishnu and his avatars (incarnations) and forms of the goddess or Devi, all often conceptualised in anthropomorphic forms.
  2. Nirguna (without attributes): Nirguna bhakti on the other hand was worship of an abstract form of God.
  • Ravidas’s teachings symbolized resistance against untouchability, confronting discrimination by higher-caste individuals against those from lower castes.
  • His egalitarian teachings are adhered by various scheduled classes, now known as Dalits, influencing social-reform movements in the 20th century. 
  • He engaged with Sufi saints, sadhus, and ascetics, fostering a diverse spiritual understanding.

In Literary works/traditions: 

His devotional verses have found a significant place in Sikh scriptures: 

  • Scholars suggest that Ravidas had interactions with Guru Nanak, the founder of Sikhism.
  • 41 of his poems are included in the Adi Granth, signifying his status as one of the 36 contributors to this central scripture of Sikhism.
  • Premambodha, a Sikh hagiography written over 170 years after his death, portrays him as one of the seventeen saints in the Indian religious tradition.
  • Dadu Panthi tradition within Hinduism incorporates numerous poems attributed to Ravidas in the Panch Vani text.
  • Anantadas Parcai, considered one of the earliest surviving biographies of poets from the Bhakti movement, narrates the birth of Ravidas.
  • Bhaktamal, proposes that he was a disciple of the Brahmin bhakti-poet Ramananda (1400-1480 A.D), and thus, it is believed that Ravidas was the contemporary of Sant Kabir. 
  • Although Ravidas's hagiographies were penned long after his demise, they shed light on social dynamics during the period he lived: 
  • Illustrate a clash between heterodox communities and the orthodox Brahminical traditions as well as an inter-communal and inter-religious struggle for social unity
  • Present various legends, including Ravidas's interactions with Hindu Brahmins and the Delhi Sultanate ruler Sikander Lodi (1458-1517).

(Footprint of Guru Ravidas)

Guru Ravidas and Meera Bai: 

  • In Chittorgarh, Rajasthan, adjacent to Mirabai’s temple, a chhatri (pavilion) with the engraved footprints of Ravidas is found. 
  • This signifies the spiritual and poetic connection between Ravidas and Mirabai.
  • As per the legends, Ravidas was a guru to Mirabai.
  • Mirabai, as a respect to her Guru, wrote: ‘Guru Miliya Ravidasji’. 

Philosophy: 

  • A recurring term in his verses is ‘Sahaj,’ representing a mystical state characterized by the union of diverse truths into a singular reality.
  • Manuscripts originating from Rajasthan and Uttar Pradesh (18th and 19th centuries), feature a debate between Ravidas and Kabir on the nature of the ‘Absolute’.
  • Kabir advocates for a monistic Oneness, while Ravidas argues from the premise that the Brahman can be both a monistic Oneness and a separate anthropomorphic incarnation. 
  • According to the Bhaktamal text, Ravidas's teachings aligned with Vedic and ancient scriptures, embracing ‘non-dualism’.
  • However, conflicting beliefs within the Dalit community suggest that Ravidas rejected the Hindu Vedas and faced opposition from Brahmins and caste Hindus, as reflected in certain hymns present in the Guru Granth Sahib.

His concept of Beghumpura:

  • Signifies a ‘city without sorrow.’
  • His vision encompassed a utopian world free from discrimination and inequality.
  • Aiming to eradicate the evil of untouchability.
  • Emphasizing the significance of labor (Kirat).
  • Ravidas followed Ananya bhakti, which emphasises on the devotion that transcends the sense of duality between the worshipper and the object of worship.
  • Rejected formal devotion and advocated for personal bhakti through meditative meditation.  
  • Disapproved of rituals, pilgrimages, and penances as the optimal paths to realize God.

Ravidassia Religion:

  • Originating in the 21st century, it emerged as a distinct faith separate from Sikhism, shaped by the followers of Guru Ravidas’s teachings. 
  • It was established following an event in 2009, when Sikh militants attacked a Ravidas temple, in Vienna, Austria.
  • Ravidassia religion formulated a new sacred text, the ‘Amritbani Guru Ravidas ji’, exclusively based on teachings and writings of Guru Ravidas and comprises 240 hymns.

Weakly Interacting Massive Particles (WIMP)

Context: In a recently published paper by Raman Research Institute (RRI), an autonomous institute of the Department of science and Technology (DST), they confirmed the relevance of Weakly Interacting Massive Particles (WIMP) by relaxing certain earlier assumptions and hence proved that theorizing dark matter from particle physics was possible.

Dark Matter 

About 80% of the matter in the universe cannot be observed through telescopes due to instrument limitations. This is due to its weak interaction with the electromagnetic waves which are used by scientists to map the universe. Because of this particular reason this part of the universe is invisible to human eyes and termed as ‘Dark Matter’. 

Despite being invisible, the presence of dark matter can be detected through its gravitational influence, evident in the orbital speed of stars around galaxies and the movements of clusters of galaxies. But this matter’s true nature and interaction with other matters remains undefined.

Cold Dark Matter (CDM)

Out of this dark matter, 25% is identified as cold dark matter. 

  • This differentiation of dark matter is done on the basis of the mass of dark matter particles and they are categorised as "cold" or "hot." 
  • According to the standard model for dark matter, Lower-mass particles are considered "warmer" and move faster and if particles are "cold," it means they move slowly compared to the speed of light and have higher mass.
  • To unravel this mystery, extensive research is ongoing. Many scientists believe that the discovery of new kinds of subatomic particles, fundamentally different from those composing ordinary matter, will lead to a resolution.

Weakly Interacting Massive Particles (WIMP)

WIMPs represent one hypothesised class of particles to explain dark matter.  

  • They neither absorb nor emit light and have weak interactions with other particles. However, when WIMPs encounter each other, they annihilate, producing gamma rays.
  • Such particles arises naturally in extensions of the standard model of particle physics and predict the correct energy density of the Cold Dark Matter for plausible range of interaction strength (WIMP miracle). 
  • However, in spite of intensive searches and orders of magnitude improvement in the sensitivity of lab experiments (e.g. Xenon based experiments), WIMP has not yet been detected.

Thirty Metre Telescope

Context: An Indian delegation led by the Secretary of the Department of Science and Technology (DST) visited Mauna Kea, Hawaii, USA and discussed challenges in the progress of the Thirty Meter Telescope (TMT) project and ways to overcome them.

About Thirty Metre Telescope:

  • TMT is an international project which aims at building a 30-metre diameter telescope at Mauna Kea, Hawaii, USA.
    • At the heart of the telescope is the segmented mirror, made up of 492 individual segments, which makes it three times as wide as the world’s largest existing visible-light telescope.
    • Precisely aligned, these segments will work as a single reflective surface of 30 m diameter.
      • The larger the mirror, the more light a telescope can collect, which means that it can see farther, fainter objects. 
  • Upon construction, TMT would be one of the world’s most advanced and capable ground-based optical and infrared observatory.
    • Wavelength: Optical, near-infrared, and mid-infrared. 
  • Estimated cost: 1.47 billion USD (Base year 2012 USD).
  • It is a joint effort of an international consortium of scientific organisations and institutions in Canada, China, India, Japan and USA.

  • Study of exoplanets and whether their atmospheres contain water vapour or methane — the signatures of possible life, and detection of extraterrestrial life.
  • Study of black holes, evolution of galaxies, dark matter and dark energy
image 50

Why Mauna Kea?

  • Mauna Kea is a dormant volcano located on Hawaii’s Big Island, USA. 
  • Astronomers favour Mauna Kea because the clean air and limited light pollution at its summit 4,205 metres above sea level make it one of the world’s best locations for studying the skies.
  • The area was selected in July of 2009 by the board of the Thirty Meter Telescope after a five-year-long campaign.
  • The project was started in 2014, but was soon halted due to opposition by native Hawaiins who consider Mauna Kea as sacred, and also concerns regarding environmental damage.
    • The indigenous people on the island argue that because of the massive size of the facility, the project would further desecrate the summit
    • The mountain has religious significance for native Hawaiians and already houses 12 observatories on the summit.
