"The basic terminology used in Vaastu Shastras, such as Vastu, Vaastu, Vaastu Purusha and Vaastu Purusha Mandala, which have already dealt extensively with the scientific significance of Vaastu Purusha Mandala, has been written in a language easily understood by an ordinary person. As for the other terms such as Kaala Purusha, Taala Purusha, Praasaada Purusha, Naatya Purusha and Sangeetha Purusha, discussed at length by Dr. V. Ganapati Sthapati.

I would now like to make a special reference to the popular view of the Vaastu Purusha Mandala, which was also encountered by ancient Shastras such as Brihat Samhita (5th century), Vastu Vidya, Agamas and the Purana. The Puranas are considered a historical epic of ancient India in the context of Vaastu. The puranas are, of course, full of moral themes, articulated in historical forms, in mythological language, which, in their narrative, record certain historical events and the cultural life of ancient people. Such things need further study and proper interpretation, especially with regard to the technical materials we come across in the Puran literature.

The ancient writers of the Puranas also recorded technical procedures that are similar to those written in the vaastuastras and sometimes supplement those missing in the vaastu texts.

Thus, their ancient writers also preserved certain scientific materials that greatly helped them to understand certain complex problems of origin, the evolution of concepts, and their material representations.

In the Skanda Purana, for example, one can meet time as the causal element of the universe and the concept of the objects of the universe.

At first, neither the Vaastu nor the Agamic texts, nor the literature from other sources — even in the Vedas — could be accessed in as much detail as those recorded in the Skanda Maha Puranas. This discovery made it possible to understand the Mayan Aintiram, where a detailed description of the science of time and space can be found.

It is to be understood that the Vaastu Purusha Mandala, as expressed in the texts mentioned above, denotes the appearance of the ancient space and spatial Forms from the ancient energy, which is the ultimate and the absolute.

It can be stated that the explosion of energy with tremendous heat (Kaalaagni) and the consequent appearance of “akasa” or “akasa bhuta” is the theory of the Big Bang in India.

The Vaastu Shastra, with which the only scientific dissertation was born from Indian genius, is no wonder that it deals with a scientific phenomenon like this, deeply, albeit in mythological language, and extends it further to the unique science of Vastu and Vaastu.

​

According to Brihat Samhita, who is considered to be older than the Vaastu Sastras, it is mentioned as the story of a BHUTA, a demonic force that provoked a severe uproar, spreading the whole emptiness with what is commonly called celestial space, or Akasa.

It is also said that the celestial lanterns (planets) called “Devas”, frightened by the terrible shape and dining noise of Bhuta, gathered their strength and suppressed the demon. The demon fell to the ground with indignation and face down. The devas occupied certain parts of the demon's body. Unable to bear the weight of the Devaganas, the demon hid in the belly of Lord Shiva and prayed to him with his head in the northeast corner. Freeing him, Lord Shiva has given him a blessing that he will be the guardian god of the built forms, and all people will worship him when they begin construction activities and when they solemnly enter the house. Almost every text written today in the name of Vaastu Shastra encounters this kind of story.

Furthermore, it is said that this is a demon called Vaastu Bhuta, and sometimes Vaastu Naga, Vaastu Nara in other works lies within a square, with folded limbs, covering the whole space.

It follows from this mythological story that the Vaastu purusha mandala is an abstraction of space and its qualities in miniature form, and also indirectly means that this miniature space is the first manifestation of unmanifested energy.

That the Vaastu Purusha is all-pervading is indicated by the extensions and folds of the various limbs within the square field.

Occupying different parts of the body, the Devaganas add another dimension to the concept of the Vaastu Purusha diagram.

This is a miniature diagram of the universe. Celestial beings like Surya, Agni, Varuna, Vayu, Kubera and other similar divine beings were included in the Vaastu Purusha arrangement complex.

In this particular miniature universe, we could identify them with the forces of nature who have taken on the subtle material form of sound and light with eight gunas, each representing a particular illuminating square. These gunas are native to the unit and should be disputed by scientific analysis. These are taken into account in the analyzes and the windows are adequately positioned during the design process.

This employs the metaphor that suggests that the essence of the universe that occupies the entire cell is the energy cell.

It also indicates the various subtle points of the energy cell that later germinate into material form. It is exactly like the core of the Banyan tree, which holds the properties and shape of the future Banyan tree.

In short, it is a complex cell of energy and matter.

This can be repeated as the “Nirguna” aspect of energy, which, while changing into the “Saguna” aspect, receives the qualities represented by celestial beings. There are the subtle qualities expressed by different celestial bodies in different parts of Vaastu Bhuta.

This means that we can say that all manifestations of manifestation, the flooding of the universe, have certain good and bad qualities that are firmly integrated into the obvious material form. That is, neither coarse nor subtle energies are free of positive and negative qualities.

Nirguna is harmless, while Saguna is generally harmful.

In other words, kinetics has good and bad effects on human life, while potential is free from evil effects.

 

The purpose of the Vaastu shastra is to understand the qualities of man and to restore the Nirguna status of “Saguna Vaastu” even on the rough level.

Therefore, Vaastu and Agama Shastras encourage the experience of “potential” or “nirguna”. The experiment is ‘nirguna upasana’ as prescribed by yogis.

For example, if the wind is light, it is a breeze and gives a calming effect to all living things on Earth. The same wind hurricane swirling wind intensifies a catastrophic impact on human life and settlements.

In other words, the Universe in which we live is full of good and bad energies that we try to avoid or repel with our spiritual efforts.

One such spiritual creation is the “building,” which we are meant to protect against the effects of the forces of nature and subtle levels of evil.

​

The philosophers talk about Nirguna Brahman and Saguna Brahman. The Vaastu Vedas speak of Vastu Brahman and Vaastu Brahman (Vastu Purushan and Vaastu Purushan). Religion speaks of Nishkala Brahman and Sakala Brahman. Jiva Atman and Paramatman are terms used by the Vedantins. Potential and kinetic energies are the words of modern science. Fine energy and material energy are the words of Prof. Einstein. These are almost synonymous. In the science of Vastu Vedik, Brahman’s Saguna aspect is responsible for all the good and bad that people have to face in everyday life. We are exposed to all kinds of negative and positive qualities of Saguna Brahman. The Vaastu shastra, aware of these two aspects of Nirguna and Saguna, successfully tried to eliminate the negative aspects and bring people into the atmosphere of Nirguna Brahman in the built space. The Vaastu shastra approach to spiritual strength, peace and prosperity is scientific and mathematical.

This means the eternal validity of the Vaastu principles.

​

The Vaastu Purusha Mandala is an illuminated square in two dimensions and a cube in three dimensions. It is the physical form of tiny particles of primordial energy. It is called ‘VINKARU’, meaning SPACE-BEAR or EGG.

In other words, it is a fetus of microscopic size.

The huge space is full of countless particles of Karu. This is what resides in our hearts, which we call “JEEVA” or “JEEVATMAN”. This is referred to as 'daharakasa' (fine space), 'antarakasa' (interior), 'ahavin' அகவிண் (inner akasa) and 'Ullam' உள்ள ம். These words are often used in the Vaastu tradition.

​

There is another concept that as long as the Earth is a branch of space, the Earth is full of tiny energy particles. The spread of subtle space into coarse space (Earth) led the traditional scientist to theorize that the universe at its original level was the tiniest particle that has the quality of calm or peace.

The earth itself should have been a cube before it spun on its own. Therefore, it turns out that all the particles of the coarse material are spherical in the final plane.

That Vaastu Purusha, the embodied energy cell is rectangular, is confirmed by the statement that:

Vaastu Purusha Chaturasra Samsthaha.

Its meaning is that Vaastu Purusha lies in a square. This is stated by Vaastu Vidya, the text on housing architecture.

How and where it comes from is contained in an Agama text called ‘Marichi Samhita’ of the order ‘Vaikhanasa’.

This yoga is subject to the practice of performing Pranayama, where we inhale and exhale prana or the breath of life to a certain extent.

​

'प्राणायामेन विक शित हृद्क मलान्तराकाशे वैश्वानर शिखामध्ये चतुरश्रं हे माभं बिन्दुनासह'

​

"Praanaayaamena vikasita hrid kamalantarakase lapswanara shikha madhye chaturasram hemabham binduna saha".

​

"When we inhale and exhale the breath of life, the space in the heart expands, from which arises the cosmic fire (in a bluish tint), at the tip of which the bond (a particle of energy or light) is angular and golden in hue."
