Vastu purusha is the presiding deity, while eight other directions have their own specific God who governs their direction. The mandala is basically a closed area in which Vastu lies down purusha means his birth from nature. On the basis of this structure and prescribed directions, construction is recommended and all physical characteristics are decided in terms of ventilation, doors, windows, location, etc.
Vastu purusha mandala is the schematic design of the cosmos on which the whole concept of Vastu Shastra is based. It is believed that Vastu purusha lies in the cosmos, which constitutes energies in a way that his head rests in a northeasterly direction that represents a balanced thought; The lower part of the body is oriented towards the southwest, which represents strength and firmness; His navel is in the center of the earth, which means cosmic consciousness and holiness; His hand is oriented northwest and southeast, which means energy.
The mandala Vastu instructs us to place different characteristics in the place of God president to obtain the maximum benefits in terms of good health, wealth, peace, progress and prosperity. Vastu’s experts frame a module to divide the areas according to which each location and direction is determined for the physical characteristic. However, the most important place in the mandala Vastu purusha is “Brahamasthana”, it is the sacred place (center) that is considered appropriate for divinity and worship.
