[5] The designs aim to integrate architecture with nature, the relative functions of various parts of the structure, and ancient beliefs utilising geometric patterns (yantra), symmetry, and directional alignments.[16] Six of the most studied, complete and referred to Indian texts on Vastu Vidya that have survived into the modern age, states Tillotson, are – the Mayamata, the Manasara, the Samarangana Sutradhara, the Rajavallabha, the Vishvakarmaprakasha and the Aparajitaprccha.[6][39] In north India, Brihat-samhita by Varāhamihira is the widely cited ancient Sanskrit text from 6th century describing the design and construction of Nagara style of Hindu temples.Examples of mandalas with the corresponding names of sites include:[6] Vāstu Śastra represents a body of ancient concepts and knowledge to many modern architects, a guideline but not a rigid code.The ancient Vāstu Śastra texts describe functional relations and adaptable alternate layouts for various rooms or buildings and utilities, but do not mandate a set compulsory architecture.[7][46] The pink city Jaipur in Rajasthan was master planned by architect Vidyadhar Bhattacharya (1693–1751) who was approached by Rajput king Jai Singh and was built by 1727 CE, in part around Vastu Shilpa Sastra principles.[7][47] Similarly, modern-era projects such as the architect Charles Correa's designed Gandhi Smarak Sangrahalaya in Ahmedabad, Vidhan Bhavan in Bhopal,[48] and Jawahar Kala Kendra in Jaipur adapt and apply concepts from the Vastu Shastra Vidya.[49][50][51] During the colonial rule period of India, town planning officials of the British Raj did not consider Vastu Vidya, but largely grafted Islamic Mughal era motifs and designs such as domes and arches onto Victorian-era style buildings without overall relationship layout.[52][53] This movement, known as Indo-Saracenic architecture, is found in chaotically laid out, but externally grand structures in the form of currently used major railway stations, harbours, tax collection buildings, and other colonial offices in South Asia.[46][52] In contrast, public projects in the colonial era were forced into crowded spaces and local layout constraints, and the ancient Vastu sastra were viewed with prejudice as superstitious and rigid about a square grid or traditional materials of construction.[52] Sachdev and Tillotson state that these prejudices were flawed, as a scholarly and complete reading of the Vāstu Śastra literature amply suggests the architect is free to adapt the ideas to new materials of construction, local layout constraints and into a non-square space.[7][45] Vastu Shastra remedies have also been applied by Khushdeep Bansal in 1997 to the Parliament complex of India, when he contented that the library being built next to the building is responsible for political instability in the country.He gives examples of Vastu consultants claiming the need to align the house to magnetic axis for "overall growth, peace and happiness, or that "parallelogram-shaped sites can lead to quarrels in the family", states Narlikar.
Ancient India produced many Sanskrit texts of architecture, called Vastu Sastra. Many of these are about Hindu temple layout (above), design and construction, along with chapters on design principles for houses, villages, towns. The architect and artists (Silpins) were given wide latitude to experiment and express their creativity.
