Vastu shastra (vāstu śāstra) means science of architecture and construction. Found in Indian subcontinent, these survive as manuals on design, layout, measurements, ground preparation, space arrangement, spatial geometry and other aspects of architecture. Vastu sastras incorporate traditional Hindu and in some cases Buddhist beliefs.[7] The designs are based on integrating architecture with nature and ancient Indian beliefs utilizing perfect geometric patterns (yantra), symmetry and directional alignments.
