Describes the primary role or purpose of the structure.

Efficiency Contributing Factor

Identifies a specific structural feature that optimizes performance.

Lifecycle Challenge

Highlights a common issue during the lifetime of the structure.

Durability Impact

Indicates a factor that could negatively affect the longevity of the structure.

Performance Enhancement

Suggests a potential innovative solution to improve structure performance.

Rock-Cut Sanctuaries/Cave Temples

Emperor Ashoka is credited with pioneering the rock-cut technique.
Excavating a rocky mountain is more efficient than constructing a temple from quarried stone, due to the complexity and cost of transportation and construction.
Notable rock-cut sanctuaries include:
- Barabar and Nagarjuni caves in Bihar
- Karli, Ajanta, and Elephanta caves in the Western Ghats
- Raths (rock-cut temples) in Mamallapuram and Ellora

Chaityagrihas/Chaitya

Used for worship and assembly.
Features:
- Ornamental façade with a small rectangular door
- Central vaulted hall with an apsidal end, divided by colonnades into a nave and aisles
- Rock-cut stupa at the rear end of the hall, allowing for circumambulation (pradakshina patha).

Viharas

Designed for religious services, with living quarters for monks and a shared courtyard.
Composed of one main hall or multiple smaller halls surrounding a courtyard with cells excavated into the walls.

Elevated 4.87 meters from the ground with a 1.80m pradakshina patha.
Features a double staircase (Sopana) on the south side.
Devotees would circumambulate the stupa clockwise, keeping their right side facing the relics.
Circular stone gateways positioned at each cardinal direction around the perimeter wall of a structure.
Measurements: 3.0 meters wide and 10.36 meters in height with two square pillars/columns capped with a lion or elephant.
Supported by three horizontal panels (architraves).
Sculptures and reliefs depicting scenes from Buddha's life intertwined with everyday events promote understanding and accessibility of Buddhist beliefs.

Digambaras

Based on the teachings of Siddhartha Gautama, a Sakya prince known as Buddha, the enlightened one.
Adopted ideas from Hinduism, including karma, but rejected the caste system and all Hindu gods.
Two main branches:
- Theravada ("the lesser vehicle"): Faithful to ancient rules.
- Mahayana ("the greater vehicle"): Worship of bodhisattvas.
Emperor Ashoka promoted Buddhism during the 3rd century BCE, but it declined in later centuries, almost disappearing by the 13th century.

Sikhism

Emphasizes the equality of all humans, rejecting discrimination based on caste, creed, and gender.
"Purusha" refers to energy, power, soul, or cosmic man.
Temple ground plans are meticulously laid out, aligning with cardinal directions and celestial bodies.
