home space and vastu
How is the concept of Vastu Purusha explained, and what does the mandala represent?
Who Vastu Purusha is
The tradition describes Vastu Purusha as a vast being, pinned face-down across the earth. His head lies in the northeast, his feet in the southwest, and his body fills the whole site. Every building is understood to rest on him. The idea is that a structure and the living being beneath it are not separate things. The health of the house and the health of the people inside are tied together through him.
What the mandala represents
Before a building is laid out, the site is divided into a grid. The most detailed form uses eighty-one squares, called padas, arranged nine by nine. This is the Paramasayika mandala. Each square belongs to a deity. The center squares are held by Brahma. The outer rings carry other divine presences, each linked to a direction or a quality. The grid is not just a plan for walls and rooms. It is a map of the cosmos laid flat on the ground. Building on it is seen as an act of bringing cosmic order into a human space.
Where these ideas come from
Texts on sacred architecture, including those known as Manasara and Mayamata, set out these ideas in detail. They describe how the mandala should be drawn, which deity governs which square, and how rooms and functions should be placed in relation to those zones. These texts belong to a long tradition of thought about how built space connects to larger forces. The exact age and origin of the ideas is debated among scholars, and the tradition developed across different regions over a long period.
How people use it today
Vastu consultants today still use the mandala as a tool for planning homes, offices, and temples. Some follow the classical grid closely. Others use simpler versions that keep the directional zones without the full eighty-one-square layout. Practice varies a great deal by region and by the consultant or family involved. Some people follow Vastu strictly when building or buying a home. Others treat it as one consideration among many. The ideas have also spread well beyond South Asia and are discussed in many countries where the Hindu diaspora has settled.
