Vastu is a combination of science, art, astronomy and astrology and indicates the influence of heavenly bodies on human dwellings.

All buildings have a direct co-relation with electromagnetic forces and gravitational field of the earth which leads to energy radiating from all directions.
Vastu and Astrology are interdependent and interrelated. From Astrology we get the information on colours, metals, five great elements related to planets and directions which is of immense value for creating Vastu- related remedial measures.
Human dwellings are an extension of human bodies just as the universe is an extension of a home. Thus our home links us to the universe.
Astrology is the science of studying the influence of heavenly bodies on humans.

In Sanskrit Vithi denotes road and Shoola denotes arrow.
VithiShoola is the name given to roads or lanes that run into the face of the plot from different directions.
These roads thrust concentrated energy of enormous potency into the site. This energy can be positive or negative depending on the direction from which they come.
Scholars are divided in their opinions about VithiShoola. Some believe that a VithiShoola from source zones ie North, North-East and East creates a positive result.
However others believe that an arrow from any direction is bound to create wounds.
Most modern scholars agree that a VithiShoola from North-North-East and East-North-East lead to good results for the residents of the house.
