Vastu Shastra (vāstu śāstra, also Vastu Veda, " science of construction","architecture") is a traditional Hindu system of design based on dirrectional alignments. It is primarily applied in Hindu architecture, especially for Hindu temples, Pleases, dueling, although it covers other applications, including poetry, dance, sculpture, etc.
While Vastu had long been essentially restricted to temple architecture, there has been a revival in India in recent decades.
While the fields are related, Shilpa Shastra explicitly deal with sculpture - forming statues , icons, stone murals etc. Vastu Shastra are concerned primarily with building architecture - building houses, forts, temples, apartments etc.
The Sanskrit word vastu means "any really existing or abiding substance or essence, thing, object, article", and also "goods, wealth, property". The vrddhi, vāstu takes the meaning of "the site or foundation of a house, site, ground, building or dwelling-place, habitation, homestead, house". The underlying root is vas "to dwell, live, stay, abide".
The term shastra may loosely be translated as "science, doctrine, teaching".
