Vãstushãstra stands tall and apart.
The Vastumandal denotes the Cosmic World and forms the basis of all Vastu planning. It represents the highest level of Design Philosophy from concept to theory to the actual process of construction. Vastumandal is always drawn square, for Square is a perfect shape, a fundamental form, and also the shape of the Earth element which contains within it the elements of Space, Air, Fire and water, as also of speech, touch, shape, taste and smell. It has poise, balance and makes a practical basis for designing a building.
The 7th chapter of Mayamatam lists the deities which occupy the Vãstumandal:
ईशानश्चैव पर्जन्यो जयन्तश्च महेन्द्रकः ।
आदित्यः सत्यकश्चैव भृशश्चैवान्तरिक्षकः ॥३४॥
अग्निः पूषा च वितथो राक्षसश्च यमस्तथा ।
गन्धर्वो भृङ्गराजश्च मृषश्च पितृदेवताः ॥३५॥
दौवारिकश्च सुग्रीवः पुष्पदन्तो जलाधिपः ।
असुरः शोषरोगौ च वायुर्नागस्तथैव च ॥३६॥
मुख्यो भल्लाटकश्चैव सोमश्चैव मृगस्तथा ।
अदितिश्चोदितिश्चैव द्वात्रिंशद् बाह्यदेवताः ॥३७॥
आपश्चैवापवत्सश्चैवान्तः प्रागुत्तरे स्मृतौ ।
सविन्द्रश्चैव साविन्द्रश्चान्तः प्राग्दक्षिणे स्मृतौ ॥३८॥
इन्द्रश्चैवेन्द्रराजश्च दक्षिणापरतः स्थितौ ।
रुद्रो रुद्रजयश्चैव पश्चिमोत्तरतो दिशि ॥३९॥
ब्रह्मा मध्ये स्थितः शम्भुस्तन्मुखस्थाश्चतुः सुराः ।
आर्यो विवस्वान् मित्रश्च भूधरश्चैव कीर्तिताः ॥४०॥
चरकी च विदारी च पूतना पापराक्षसी ।
ईशानादि बहिः स्थाप्याश्चतुष्कोणे स्त्रियः स्मृताः ४१॥

The vertical, horizontal and diagonal lines of the Vastumandal define various cosmic energies and their flow paths. Each side of the Vastumandal is divided into several different parts called pada. Mandals are drawn from 1×1 pada for designing ceremonial alters upto 32 x 32 pada for designing townships. The most common mandal, however, is of 9×9 pada which is generally accepted for all building designs. Each pada is governed by a deity whose encoded name carries the attribute of that pada.
The central region of 9 squares is called Brahmavithi and has the highest concentration of energy. No construction should be done here. Surrounding it is Devavithi, the region of gods, and Manushyavithi, the region of humans. Construction is allowed in these two zoness. The outermost area is called Pishachvithi, the region of darkness where again no construction is allowed.
The Vastumandal is crisscrossed by lines which are called nadi, rajju and sutra. These lines represent the Energy Meridians of a plot, and the points where they intersect are called Marma. These Marma are classified as Upamarma, Marma, Mahamarma and Atimarma. The Mahamarma and Atimarma are very delicate and should not be disturbed, and therefore it is very important to identify their position and size before planning a building.
Ayadi calculations are a set of six intricate calculations which are made to check the energic suitability of the plot and its relationship with the owner. For details click on give here the link to the page on Ayadi Calculations.
Yoni: Direction of Energy Flow
Yoni calculation determines the direction of the flow of prana of the land. The direction of the flow of Energy of a plot depends upon the size of its perimeter. The flow of energy in cardinal directions sustains life and growth whereas its flow in the four corners of the Vastumandala is detrimental to growth and prosperity.
Direction of Energy Flow
East, West, North, South
Effect on the occupants
It enhances financial fortunes, good health, victory and success in competition, and overall prosperity
Direction of Energy Flow
North-East, North-West, South-East, South-West
Effect on the occupants
Causes ill health, bad fortunes, loss of money, failure in career, shattered happiness, fractured relationships

The attributes of different directions of the Vastumandal determines the placement of various building components on different parts of the plot. Broadly, East denotes Light, West denotes Darkness, North denotes Birth and South denotes Death. NE is the source of all energies, and SW is where they travel and disappear. Based upon these attributes, certain areas are preferred low and free of heavy construction while some are preferred raised. Here is a summary:
A depression promises wealth, riches, and a longer life; an elevation foretells loss of children.
A depression promises wealth; an elevation foretells miseries, losses and poverty.
A depression promises wealth; an elevation foretells losses and poverty.
Should be lower than SW and SE but higher than NE. Lower than SW indicates success and wealth. Higher than NE indicates illness and rivalry for the residents.
Should be higher than N and E but lower than S. Such land indicates good name, success in life, and long relationship with children.
High SW enhances prosperity. Depressed SW indicates premature death, chronic illness and bad habits.
Should be elevated to ensure prosperity and health. Depressed S causes sickness and poverty.
Should be higher than NE and NW but lower than SW to bring wealth. If it is lower than NE and NW it accidents by fire. The residents will develop a criminal mentality.
