Bodh Gaya Temple
Why in news?
- Since February 2024, Buddhist monks under the All India Buddhist Forum (AIBF) have been protesting, demanding the repeal of the Bodh Gaya Temple Act (BTA), 1949.
About Bodh Gaya Temple:

- Location:
- The Bodh Gaya Temple is located in Bodh Gaya, Bihar, India, on the banks of the Niranjana River.
- It is one of the four most sacred Buddhist sites, along with Lumbini (Buddha’s birthplace), Sarnath (Buddha’s first sermon), and Kushinagar (Buddha’s parinirvana).
- Establishment and Historical Significance:
- Emperor Ashoka built the original temple in the 3rd century BCE, marking the site where Gautama Buddha attained enlightenment under the Bodhi Tree.
- The present structure dates to the 5th–6th centuries CE and is one of the oldest surviving brick structures in India.
- Over centuries, the temple remained a centre of Buddhist learning, especially during the Pala Dynasty, but declined after Bakhtiyar Khilji’s invasion in the 13th century.
- In 1590, a Hindu monk established the Bodh Gaya Mutt, leading to Hindu control over the temple.
- The British-era records continued to refer to Bodh Gaya as a Hindu-controlled site until India’s independence.
- The temple complex was designated a UNESCO World Heritage Site in 2002.
- Architectural Features:
- Grand Temple: A 50-metre-high pyramidal shikhara (tower) with intricate carvings and motifs.
- Four smaller towers surround the main temple, each topped with an umbrella-like dome.
- Sacred Bodhi Tree: Believed to be a direct descendant of the original tree under which Buddha attained enlightenment.
- Vajrasana (Diamond Throne): A stone slab marking the exact meditation spot of Buddha.
- Temple Shrine: Houses a yellow sandstone statue of Buddha, encased in glass.
- The 4.8-hectare complex includes ancient shrines and modern Buddhist structures built by devotees.
- The Bodh Gaya Temple Act (BTA), 1949:
- Passed by the Bihar Assembly, the Act aimed to formalise temple management, transferring control to a management committee instead of a single Hindu authority.
- The Act established an eight-member management committee with equal representation for Hindus and Buddhists, but the District Magistrate (DM) was made the ex-officio chairperson.
- Historically, since the DM was often a Hindu, it created a perceived Hindu majority in temple administration.
- Protests Against the Act:
- Buddhist organisations, including the All India Buddhist Forum (AIBF), have long demanded full control over the temple, calling it Bodh Gaya Mahavihara.
- Since February 2024, Buddhist monks have been protesting, seeking repeal of the BTA, 1949, arguing that the temple should be administered solely by Buddhists.
- In the early 1990s, Bihar CM Lalu Prasad Yadav draughted the Bodh Gaya Mahavihara Bill to transfer temple management to Buddhists, but the bill was never passed.
- The 2013 amendment allowed the ex-officio chairman (DM) to be from any faith, but Buddhist groups continue to demand full control.

Tonga
Why in news?
- A powerful 7.1 magnitude earthquake struck near Tonga, triggering a tsunami warning for the region.
About Tonga:

- Location:
- Tonga, officially the Kingdom of Tonga, is an archipelago of 169 islands, with only 36 inhabited.
- It is located in the South Pacific Ocean, south of Samoa, east of Fiji, and just north of the Tropic of Capricorn.
- The three largest islands are Tongatapu, Ha'apai, and Vava'u, with Nuku‘alofa as the capital on Tongatapu.
- Geophysical Characteristics:
- Tonga’s western islands are volcanic, with four active volcanoes, while its eastern islands are low-lying coral formations.
- The nation is part of the Pacific Ring of Fire, a seismically active region prone to earthquakes and volcanic eruptions.
- Due to its tectonic setting, Tonga frequently experiences seismic activity, tsunamis, and volcanic eruptions.
- Reason Behind the Earthquake:
- Tonga is located near the Tonga Trench, a subduction zone where the Pacific Plate is forced under the Indo-Australian Plate.
- This subduction results in intense seismic activity, leading to frequent earthquakes and tsunamis.
- The recent 7.1 magnitude earthquake was caused by tectonic stress release along this subduction zone.
- Impact of the Earthquake:
- The earthquake triggered a tsunami warning, raising concerns for coastal communities.
- It caused infrastructure damage and disrupted communication and transportation networks.
- Local authorities advised evacuations in vulnerable areas due to the risk of aftershocks and potential tsunamis.
