Vastu
Vastu Shastra are the textual part of Vastu Vidya – the broader knowledge about architecture and design theories from ancient India. Vastu Vidya is a collection of ideas and concepts, with or without the support of layout diagrams, that are not rigid. Rather, these ideas and concepts are models for the organisation of space and form within a building or collection of buildings, based on their functions in relation to each other, their usage and the overall fabric of the Vastu. Ancient Vastu Shastra principles include those for the design of Mandir (Hindu temples)[9] and the principles for the design and layout of houses, towns, cities, gardens, roads, water works, shops, and other public areas. The Pandit or Architects of Vastu Shastra are Sthapati, Sūtragrāhin(Sutradhar), Vardhaki, and Takṣhaka.
