living concurrently provides positive energy,prosperity and good health to the inhabitant. A place of living and its direction have a interconnection between the revolvoing synopsis of the planets with respect to the north direction.

As we all know that there are eight directions North, South, East and West and they all are called as cardinal directions and the point or place where either of the two directions meet is called as sub-directions/ordinal/intercardinal point such as NE,NW,SE,SW.In Vastu Shastra these directions have lot of significance as they integrate the aid of two directions.

According to our Shastra if we worship,honor and idolize the Lords of these directions, inhabitants achieve constant blessings in the form of success, prosperity and health. We will now examine their importance according to scriptures.

North: This is a direction which is governed by lord Kuber,the god of prosperity.

South: This is a direction of god of death called as Yama. He is a mark of dharma,removes evil forces and gives all the good things. It is a source of pleasure and of wealth.

East: This direction is directed by the lord Indra and he is the king of all Gods. He gives wealth and joy in life.

West: This direction is governed by the Lord Varun also called as the lord of rains. He gives his good wishes in the mode of a natural rain-water,pleasures of life and prosperity.

North East: This sub-direction is governed by the lord Eeshaan also called as “Eeshan corner” and is a source of health, wealth and success.
This is a corner where the North and East parts meet.This corner is governed by the planet Jupiter and water component. This place in a house is use for a  pooja while for a living room it is also used.
Now, having kitchen, bedroom or toilet etc. in this corner is a Vastu defect.

North West: This is the place where the North and West parts meet and it is ruled by “Air” and “Moon”and known as “Vayu” or “Air” corner.

This corner is best for kitchen, bedroom or living room.There are Vastu defects that occur in NW sub-direction of a house.This sub-direction is directed by the lord Vayu and he provides long life, good health and strength and is a source of turnover in a progress of business and friendship.

South East: This sub-direction is governed by lord of Agni- Fire.This is the corner where the South and East parts meet and is ruled by the planet “Venus” and the“Fire” element and is called as the “Fire” or “Agni” corner.SE corner provides us all the good things of life and even good personality.As it is related to cooking and food so it is a source of health.The SE is best for a kitchen in a house and not suited for bedroom, living room or toilet as it is a big vastu defect.

South West: This is a direction of god Niruti who save us from bad foes and is a source of demeanor, character,longevity and death.
This is the corner where the South and West parts meet and it is ruled by the planet “Rahu”and the“Earth” component/element. It is also called as the “Nairutya” corner.
