The science of Vastu is closely connected with architecture, village and city planning, construction and many other aspects of our daily lives.
For example, in designing the Gurukula Colony, according to Vastu, the Yajna Shala and the kitchen (fire) will be located on the SE side of the colony while the pond (water) will be situated on the NE side of the colony. According to Vastu principles, the roads will be at right angles.
