Varaha Cave Temple
Varaha Cave Temple (also Varaha Mandapa) is a rock-cut cave temple located at Mamallapuram, on the Coromandel Coast of the Bay of Bengal in Kancheepuram District in Tamil Nadu, India. It is part of the hill top village, which is 4 km to the north of the main Mahabalipurm sites of rathas and the Shore Temple. It is an example of Indian rock-cut architecture dating from the late 7th century. The temple is one of the finest testimonial to the ancient Hindu rock-cut cave architecture, out of many such caves also called mandapas. Part of the Group of Monuments at Mahabalipuram, the temple is a UNESCO World Heritage Site as inscribed in 1984 under criteria i, ii, iii and iv. The most prominent sculpture in the cave is that of the Hindu god Vishnu in the incarnated form of a Varaha or boar lifting Bhudevi, the mother earth goddess from the sea. Also carved are many mythical figures.
Hindu temple architecture
Hindu temples in South-East Asia developed their own distinct versions, mostly based on Indian architectural models, both North Indian and South Indian styles. However, the Southeast Asian temple architecture styles are different and there is no known single temple in India that can be the source of the Southeast Asian temples. According to Michell, it is as if the Southeast Asian architects learned from "the theoretical prescriptions about temple building" from Indian texts, but never saw one. They reassembled the elements with their own creative interpretations. The Hindu temples found in Southeast Asia are more conservative and far more strongly link the Mount Meru-related cosmological elements of Indian thought than the Hindu temples found in the subcontinent. Additionally, unlike the Indian temples, the sacred architecture in Southeast Asia associated the ruler (devaraja) with the divine, with the temple serving as a memorial to the king as much as being house of gods. Notable examples of Southeast Asian Hindu temple architecture are the Shivaist Prambanan Trimurti temple compound in Java, Indonesia (9th century), and the Vishnuite Angkor Wat in Cambodia (12th century).
Hindu temple architecture
A Hindu temple is a symmetry-driven structure, with many variations, on a square grid of "padas", depicting perfect geometric shapes such as circles and squares. Susan Lewandowski states that the underlying principle in a Hindu temple is built around the belief that all things are one, everything is connected. A temple, states Lewandowski, "replicates again and again the Hindu beliefs in the parts mirroring, and at the same time "being", the universal whole" like an "organism of repeating cells". The pilgrim is welcomed through mathematically structured spaces, a network of art, pillars with carvings and statues that display and celebrate the four important and necessary principles of human life—the pursuit of artha (prosperity, wealth), the pursuit of kama (desire), the pursuit of dharma (virtues, ethical life) and the pursuit of moksha (release, self-knowledge).
