Vastu purusha mandala is the schematic metaphysical design of the cosmos on which the entire concept of Vastu Shastra is based. Vastu purusha is believed to be lying on the cosmos, which constitutes energies in a way that his head rests in a northeast direction, representing balanced thinking; Southwestern-oriented lower body representing strength and firmness; his navel is in the center of the earth, which means cosmic consciousness and holiness; his hand faces northwest and southeast, which means energy.
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 purusha is lying signifies his birth from nature. Based on this structure and the prescribed instructions, construction is recommended and all physical characteristics are decided in terms of ventilation, doors, windows, location, etc.
Vastu’s mandala instructs us to place different characteristics in the place of presiding over God to obtain the maximum benefits in terms of good health, wealth, peace, progress and prosperity. Vastu experts frame a module to divide the areas according to which each location and direction for the physical feature is determined. However, the most important place in Vastu purusha mandala is “Brahamasthana”, it is the sacred place (center) that is considered appropriate for divinity and worship.
The Vastu purusha mandala is followed by all experts with due respect and dignity in different design structures, including temple, hospital, home, office, factory, etc.
