Sun is the source of creative process on earth. The entire physical world composed of atoms is influenced by the rays of the sun. That is why the sun is worshipped as a maifestation of the God. Modern man,who once disbelieved sun as God, has now started considering him as a potential source for creation on the surface of earth. The diameter of the sun is 8,65,380 miles. Powerful fumes generated by the thermonuclear reaction on the sun travel with a super sonic speed. The quantity of heat generated by the sun is expected to be about 3.7 x 1026 watts. However the planet earth receives only a fraction of the above heat. But that fraction itself is enough to keep the vegetation ,trees and food production sufficient for the existence of living organism. The water vapour,formed because of the rays of sun , turns into clouds and bring us rain.

Scientists have proved that the sun rays have many positive effects on human body. It is said that basking in the morning sun after applying any vegetable oil to the body,helps in the formation of vitamin’D’ in the body, which has a curative effect on diabetes. The rays of the sun are composed of seven colors forming a spectrum viz.,violet,indigo,blue,green,yellow,orange and red and this phenonmenon is made use of in nature cure whereby the process of reflection of rays through mirrors on human body,is adopted for curing certain diseases. So,is the immense invaluable power of the sun. That is why our ancestors had presented Surya Namaskaras as alma medica for best physique.

With the development of science of Vastu , man has started constructing houses as per the tenets and thus the positive influence of the five elements viz., earth,water,light,air and sky could be realised. House is the inseparable factor in the life of man. This has been realized and a science is evolved about it, which is called Vastu.

As per Vastu, land extending from east to west is termed as ‘Purush Sthana’ (Masculine site) and is considered as the best, because it is exposed to sun light more prominently . To ensure free and direct access to the morning sun rays,the science of Vastu forbids any type of high structures or tall trees in the eastern side of the building. Further it has been prescribed ,that the vacant space in east must be more than that of west. It is laid  down that tall trees should be planted in the west,to prevent the powerful rays of the sun during the afternoons , causing harm to the human beings and for helping the process of photosynthesis.The effect will be vice versa if the trees are grown in the east. With the growing threat of Green-house effect due to the extinction of ozone layer,the tall trees in west and south have become the only phenomenon,which would come to the rescue of the residents in any house,and at the world at large.

The logic behind the principle of leaving more vacant space in north also is to ensure more quantity of sunlight to the inhabitants during Uttarayana (Northward movement of the sun). The northward movement of the sun during the period of December 21st to June20th is called Uttarayana. The southward movement of the sun during the period June21st to December 20th is called Dakshinayana.

During the Uttarayana period many diseases and ailments , that were prevalent during Dakshiyana,subside and cause less suffering. That is why the wise suggest,that for performing marriages,undertaking construction activity and for other auspicious projects,Uttarayana period proves to be congenial. Bheeshma the staumch warrior and the commander-in-chief of Great Mahabharata battle lied upon the bed of arrows awaiting for the arrival a Uttarayana,and left his last breath on Ekadashi,after teaching all the secrets of jurisprudence,ethics and philosophy to Yudhisthira,on the request of Sri Krishna. The reason behind such logic is the positive impact of the rays of the sun during the period.

In order to derive maximum benefits out of the sun rays during Uttarayana, it is suggested that there should be more vacant space in north and east rather than in south and west. Contrary to it the vacant land in south and west would prove detrimental to the interest of the structures , be it a house,industry,hut or a temple and paves way for its dilapidation.


The environment of a plot is long standing, powerful and often determines the running of a factory. Many factories have Vastu unfriendly locations. The following are the reasons .

  • The human habitations like cities or villages have survived for a long time and therefore must have a favourable Vastu environment. If the Vastu environment had been bad,the habitations would have been abandoned much earlier due to unlivable conditions.
  • The factories have high needs for water as a medium for waste disposal and also as a industrial input. Thus they end up near rivers or lakes with either highly favourable or unfavourable slopes.
  • Large areas are needed for factories. Hence they are exposed to more features of the environment than a smaller factory plot.
  • The agricultural land is often converted to industrial areas. These plots placed on the road side will have large areas on the back. Even if both the sides are developed as factories the open space will be bad for north and east facing factories as they are open spaces on the south and west respectively.
  • Government developed industrial estates have to be developed in large uninhabitated areas. These often turn up to be dried up lake beds. These have very high water tables and unpredictable slopes both of which are unfavourable.
  • The rapid industrialization of an area leads to hazardous construction of temples , electricity installations,pillars and other buildings which affect the neighbouring areas.      Hence the chance for a factory to be built in a Vastu unfriendly locale is very high. Due care has to be taken for choosing the ideal plot before construction.

Vastu Tips for all rooms

The Bathroom

The East sector is best  suited for a bathroom since the beneficial rays of the morning sun fall into the room. The slopes within the bathroom can be towards north and east so that water drains into the north-east of the bathroom.

Master Bedroom

The Southwest sector is for the master’s room. Sleep with your head to the south. Outside the master room, a rock garden can be made. This’ll provide a natural setting as you look out from the window. This room can be occupied by the father or the eldest son of the family.

Children’s (Study)Rooms

Children’s room can be in the West, North or East sector. They can have their beds to the South-west corner of the room. Let them sleep with their heads to the East or West. A soft green light in the night will be instrumental in making them study well.

Guest Rooms

The guest room is ideal in the North-west room. Avoid children in this region,especially boys. This room is also suitable for newly wed couples and for those planning their baby.


The right place for kitchen is the South-east sector of the building. Face the east while cooking . the ovens and the gas stoves can be in the Southeast corner of the kitchen. The alternate place for the kitchen,in case you are not able to have the kitchen in the South-east is the North-west sector of the building. To stimulate appetite have your kitchen walls painted soft pink or orange. As good food is indicative of financial strength, a mirror on the North of Eastern wall of the kitchen will likely help strengthen finances.

Dining Room

East, South or West are for the dining rooms. Stimulate your appetite by painting its walls shades of pink or orange. The dining room can be an independent room or a continuation of the kitchen. The suggested place is West. The dining table, preferably a rectangular one should be so arranged that the master of the house,or his wife or eldest son occupies the South of South-west or West of South-west chair in the room.

Living Room 

Living rooms can be in the North-east sector of the building. Avoid loads in the centre of the living room. An east of North-east entry is preferred with good space to the right as you enter the house.

Prayer Room (Shrine)

Prayer room or your private shrine can be either in the North-east sector or the centre of the house which corresponds to the Brahmsthana. Let the Deity be on the Eastern side. Pyramid shaped roofs can immensely strengthen the room spiritually. Avoid having photos of dead people along with the photos of the Lord… Keep the puja room absolutely clean. Never have the prayer area in the bedroom.

Store Rooms

The granaries can be in the North-west sector. Lofts and attics can be on the South and West walls. Grains that needed for daily use can be in the North-west corner of the granary.


Toilets are to be in the North-west of the sector. Avoid them in the centre of the building and the North-east of the building. When it has to be an attached toilet,let it be to the North-west of the concerned room.

The second alternate is the South –east of the building or the room.

General tips for rooms

South-east bedrooms may be avoided. Blue color induces sleep. Green is good for study. Almirahs and lofts can be in the South or West of the rooms. Avoid beds in the centre of the room and under beams. Do not sleep with your head to the North.


Garages can be in the North-west sector. A second choice for garages is the South-east. Avoid your garages or portico in South-west. Let not the garage touch the main building. Let the car face North or East.

Basements and Cellars

The North, East and North-east are ideal for basements and cellars. Avoid basements and cellars in the South-west.

A height equal to or less than the ground floor height is generally recommended.


Staircases may be anywhere except in the North-east and the centre of the pace viz brahmsthana.  However as much as possible prefer them in the South, West or South-west. The space beneath the staircase should not be occupied by anyone.

Verandahs or the first room into the structure

Verandahs or the first rooms into the structure can be in the East or North.have a proper maindoor or mahadwara as advised by the team of Astrobit. Mirrors can be placed on the East and /or North walls to reflect the spaciousness of the verandah.
