The logic Of Science Behind Vastu

It is amazing to know that the Vastu principles discussed in our ancient books are built upon solid foundations of science to provide all round prosperity for the dweller. In this article, I will cover the scientific basis behind the core Vastu principles.
The entire life in our Universe is based on the five elements namely Fire, Earth, Air, Water and Sky. These five elements are found everywhere and anywhere. Even our body is composed of these five elements only. When any of these elements happen to be in excess or less in our body, it will result into physical or psychological problems. For example, if Fire element is more, we will get physical problems like high BP, insomnia, ulcers and psychological problems like anger and tensions. When Water element dominates, it leads to laziness, hallucinations, fickle mindedness, obesity and indigestion. Vastu is a science of architecture which is aimed at balancing these five elements.

Understanding the elements:

In our solar system, Sun provides life by giving enough light and heat which makes the life possible on Earth. This is the reason our Vedas and Upanishads praised Sun as supreme soul (God). Sun rays travel in the Sky and reach our Earth. Thus the Sky element is the carrier of life energy. Sky element should be enough to carry abundant life force into our house.

Before constructing the house or building, we should take the measurements of the plot or land. The Sky element is 9% of the length and 9% of the breadth around the plot. For a plot with 60 ft length and 50 ft breadth, we should leave around 5.4ft along length and 4.5ft along the breadth as Sky element. The Sky element surrounds the entire house something like a box as shown in the Figure 1. Remember, the actual construction should be done after deducting space for Sky element. So the actual construction length will be 60-5.4 = 54.6 ft and breadth will be 50-4.5 = 45.5 ft.

We should leave the space for Sky element around the house or building. The Sky element can be kept more by leaving more space around the house or building. In that case, we should leave more space towards East and North directions. It means the house or building should be constructed towards the S-W direction in the plot.

After deducting space for Sky element, only the remaining area (54.6 X 45.5) should be used for actual construction. This area should be divided into 4 equal parts of each 25% as shown in Figure 2. Part1 starting from middle of North till middle of East is represented by Water element. Part2 from middle of East to middle of South represents Fire element. Part3 from middle of South till middle of West represents Earth element. Part4 from middle of West to middle of North represents Air element.

After finding the elements in the plot, the next step is to find the Brahma sthana. Brahma sthana represents the place where lord ‘Brahma’ the creator resides. It is a mixture of all the 5 elements (Water, Fire, Earth, Air and Sky) since Brahma is the creator for all the 5 elements. Brahma sthana is a rectangular area with 1/3rd of the length and 1/3rd of the breadth in the center. Take the length and breadth of the actual construction area and divide each with 3. In our example, 54.6/3 = 18.2 ft and 45.5/3 = 15.2 ft. So the Brahma sthana in our building will be in the exact center in a rectangular form with 18.2 ft length and 15.2 ft breadth as shown in the Figure 2.

Balancing the five elements:

It is essential to balance these five elements. The Sky element should be 9% of the length and 9% of the breadth. Even if the Sky element is more, there is no problem. But it should not be less than 9%. Water, Fire, Earth and Air elements should occupy exactly 25% of the construction area. Brahma sthana should be a rectangular area with 1/3rd of the length and 1/3rd of the breadth in the center. This is how these elements should be kept balanced. If any of these elements are deficit or excess then there will be problems to the residents of that house, as shown in the following table:

Element Result if not balanced
Water Losing God’s grace, loss of male children, generation will not continue, draining of all wealth.
Fire Quarrels between wife and husband, court litigation, problems to females, getting into debts.
Earth Severe and chronic illhealth, accidents, death of owner, problem to eldest child, loss of money due to bad habits and enemies.
Air Loss in business, mind related problems, loss of immovable property and cattle.
Sky The subtle energy flow cannot reach, so there will be loss of God’s grace, unexpected situations, mental problems, possession of spirits or devils.
Brahma sthana Problems related to stomach, genitals and lower parts of body. Women will face abortions and children will not survive.


1. An element is said to be imbalanced, if the area of the element is extended or reduced. See Figure 3, where South-East corner is extended and hence there is excess of Fire element in that plot. In Figure 4, the South-West corner is cut off and hence there is deficit of Earth element. This is the reason behind the Vastu principle that construction should not be done in plots with irregular shapes like triangle or hexagonal.

Case: Year 2000. A house in Hyderabad, India where S-E block is constructed protruding out. Hence S-E is dominating. The owner of this house, a Government official has lost his job immediately after the construction of the house. He stays in the house and quarrels with his wife. His wife is soft and noble. Later, I came to know that he applied for divorce from his wife.

2. Since our soul has taken physical form and we live on this material earth, the Earth element can be a little bit raised when compared to other elements. Next to Earth, we can have Fire element a little bit raised and then Air and lastly Water. Since Water naturally flows downwards, Water element can be a bit lowered in the house. It means, when construction is done, the flooring should start at a height of 5 or 6 inches in the N-W and should slowly slope down towards N-E. This applies to flooring as well as to rooms constructed on the terrace. If a room is built on the terrace in the N-W corner, there will not be any problem as the Earth element is raised. But if the room is built in N-E or East side, and the remaining directions are free, then it leads to problems.

In Figure 5, the house has Water and Air elements dominating when compared to the other two elements which results in Vastu problem.



3. When there is no sufficient place around a house or building, it leads to imbalance of Sky element. See Figure 6, where the house is in between two gigantic buildings. The Sky elements of the two buildings overlap the Sky element of the house and hence the people live in that house will face problems.

4. Mixing the opposite elements will lead to chaotic environment. For example, in the Figure 7, kitchen is constructed in the Water element. As kitchen represents Fire, it is being mixed with Water element will cause problems to the residents.

Case: Year 2009. A house at Palakol, India. The toilets are constructed in the N-E part of the house. The owner of the house has two children. The owner died due to illhealth. Later, their daughter died by committing suicide. Recently their son has developed problem in the kidneys and both of his kidneys stopped functioning. N-E is considered as sacred direction because the pranik energy comes from N-E. So, a toilet should never be constructed in N-E or East or North. It should be in South, S-W or West.

5. Brahma sthana which lies in the center of the house should be left free. This means, a pillar or wall should never be laid in the brahma sthana.

Uniform flow of pranik lines:

The pranik (life) energy which comes from Sun and other planets comprises of various types of energies like magnetic energy, light, thermal energy, gravitational energy and various types of radiations. These energies reach the people live on this earth and influence the parts of their body. For example, scientists found millions of Ferrous Oxide crystals in human brain which are highly influenced by the magnetic and electrical fields. Such magnetic material is also available in the other parts of human body.


The pranik energy enters the house mainly from East, as Sun is the principal source for it. When the house is constructed in alignment to the four main directions, East, West, North and South, the pranik energy distribution in the house will be uniform. See Figure 8. This will ensure good health to the residents. On the other hand, if the house is constructed in deviation from the main directions, then the pranik energy flow will be uneven and zig- zag. See Figure 9. This leads to health problems both physical and mental. This is the reason why Vastu does not prefer houses facing the corner directions like N-E, S-E, S-W or N-W.

Ball Bearing Information

Ball bearings are used in virtually every type of machine, motor and transportation mode. They are one of several types of rolling bearing that include cylindrical roller bearings and tapered roller bearings. Ball bearings can handle moderate radial and thrust loads and extremely high shaft velocities. Ball bearings come in every size from tiny for watches and other instruments to enormous for huge construction equipment. Their versatility, reliability and relatively low cost make them the most popular of all rolling bearings.

Bearing Types
There are two basic types of mechanical bearings used in machinery: sleeve bearings and rolling bearings. Bronze sleeve bearings are simple and inexpensive, but tend to be limited in the shaft velocities they will support. They also have considerable coefficients of friction that may consume a large proportion of the energy available to turn the shaft. Ball bearings, however, are almost limitless in the velocities they will tolerate as long as their lubrication is sustained.

Bearing Components
Ball bearings consist of three main sections, all of which are uniform and hardened for long wear: The inner bearing race fits snugly on the turning shaft. The outer race is a collar that fits snugly inside the bearing holder bore. Finally, there is a single or double row of uniform balls that may be touching one another or spaced at intervals between inner and outer races and retained by a ball cage. These bearings will last almost indefinitely if sealed, kept very clean and lubricated with a high film strength bearing lubricant.

Applications
Ideal applications for ball bearings are industrial machines that present both radial and axial loads, and moderate to high shaft velocities. On vehicles, they are preferred for moderate load bearings for motors, gear cases, and turbochargers. Modelers often use miniature ball bearings to extract the most performance from their cars, boats and planes.

Making Ball Bearings
The secret of caged ball bearing making is that the inner race is first inserted inside the outer race, and pushed to one side so it contacts the outer race. The balls are inserted into the large gap on the opposite side until about half of the space is filled. Then the balls are evenly interspersed and subsequently retained by stamped metal cages, making the inner and outer races concentric. The cage halves are then riveted together and the bearing seals, if any, added. This assembly configuration is the Conrad method and is by far the most widely used because of the ability of the finished bearing to handle both radial and axial or thrust loads. Other less-used methods are slot fill and split race which allow a higher ball density, but compromise axial loads.

Variations
Single row deep groove ball bearings are the most common, followed by double row, and self-aligning. Bearings may be shielded, sealed or double sealed. Some have grease fittings, some come permanently lubricated, and in the case of turbochargers, are continuously pressure lubricated with motor oil.

How Are Ball Bearings Assembled?

Parts
A finished ball bearing is comprised of four parts, which are manufactured separately before being assembled together--the inner race, the outer race, the balls and the cage.

Races
The inner race and outer race are the easiest parts to make, each consisting of a simple cylinder of steel. They are cut from steel pipes, a narrow band which is then smoothed and heat treated. The outer race is larger than the inner race, so that when the inner race is fitted within the outer, there is enough room for the balls to fit in between them.

Balls
The balls are formed from cut wire, which is shaped in a spherical press. The imperfections are smoothed and the balls are heat treated.

Cage
The cage is the mechanism that holds the balls in place in between the inner and outer race. It consists of one frame for each ball in the ball bearing assembly. In a metal cage, the frames are created separately and then fused together. In a plastic cage, they are formed with one mold.

Assembly
The balls are placed inside the cage and the outer race, and then the inner race is inserted into the middle. The balls, held in place by the cage, each have one point of contact with the outer race and one point of contact with the inner race.

4 Key Ways To Maximize Bearing Life In Food Processing

Food and beverage processes subject bearings to the harshest conditions, including high-pressure washdowns, frequent contact with acids, cooking fats and other chemicals, moisture saturation, extreme temperatures and antibacterial cleansing solutions. These vital components must not only withstand these extreme conditions but resist peeling, chipping, flaking and corrosion.

How can you maximize bearing life so that downtime is less costly, clean-ups are quicker and maintenance is easier? There are four key factors to keep in mind when selecting and maintaining bearings for the food industry:

PROPER LUBRICATION
Using the correct lubrication in the correct quantity can extend bearing life.Lubricants used in the food industry are classified asFDA/USDA H1 or H2 approved. Over lubricating or under lubricating bearings can increase friction and cause bearing failure. It is necessary to identify the right amount of lubrication for the particular environment. Additionally, there are a wide variety of greases available and not all greases are compatible. Consult ARB Bearings Limited to determine the correct type and amount of lubrication to maximize bearing performance and lifespan in your work environment.

BEARING TYPE AND STYLE
Selecting the correct bearing type and style makes all the difference to a bearings lifespan. Stainless steel bearings provide corrosion resistance in wet environments.

CORRECT HOUSING FOR THE APPLICATION
For food applications, look for non-toxic, thermo-plastic reinforced with stainless steel. The advantage of these is that their smooth finish helps prevent bacteria from lodging in gaps or cracks. They are also chemical resistant for less chipping or flaking during washdowns with detergents. Look for a solid base to prevent water and contamination from collecting to inhibit bacterial growth.

SEALS AND END COVERS
Other components that can help prolong bearing life include:

Seals - these provide extra protection for bearing lubrication while preventing contaminant entry.
End covers for housed units - food grade units are made of thermo-plastic and non-food grade bearings are made of pressed steel. End covers solve issues related to exposed shaft ends, such as Workplace Health and Safety concerns as well as possible contamination.

ARB Bearings Limited specializes in precision machine technology, refined through years of bearing manufacturing. Our extensive list of products includes high temperature bearings, mounted units complete with end covers designed to easily clip on without requiring special housings and more.
