and researching on Vastu Shastra it is very important to know about our Planetary
System where we are living and all things around us. We live on Earth. Please see
the Figure 1.1.
The above figure shows that Sun is at the Center and planets Mercury,
Venus, Earth, Jupiter, Saturn, Uranus, Neptune, Pluto move around the Sun, at the
moving time they also rotate around their axis. Our planet Earth is third from the
Sun. We are living on Northern Hemisphere of the Earth. Before entering the subject
we must see what are the North Pole and South Pole, what are Magnetic North Pole
and Magnetic South Pole. The Earth is like a globe. In Vastu Shastra it is very
important to know the directions. What is True North: The Earth is rotating about
an axis that cuts the globe at two points, we shall call these two points as the
True North Pole and True South Pole. The axis of rotation is tilted at an angle
66°.60' to the plane of the elliptic path of the Earth around the Sun. When extended
it should meet the surface of a fictitious Earth Globe, since the Polaris (Dhruv)
appears to be fixed in the Sky. A star revolves around it. The True North is well
defined. Please see the
Figure 1.2 & 1.3.
True North and South Poles are defined
as the point where the axis cuts the Earth. Today this axis of rotation of the Earth
is pointed towards polaris, in 3000 BCE it pointed to Tuban, in 14000 CE it will
point towards Vega, in 22800 CE it will be pointed again towards Tuban. Please see
the
From this we can see that there is actually no such thing as the
True North, it changes with time. For this reason we shall take Astronomical North
instead of True North. The question is that while measuring the directions in Vastu
Shastra, should the Astronomical North or True North be taken as reference? We know
that the Astronomical North is not fixed but keeps changing from time to time. In
map we use what is known as Grid North. The difference between Astronomical North
and Grid North is about half a degree but this changes slowly with time. For surveying
purpose Grid North is used. How the Magnetic Field is Created: The Earth consists
of a solid inner hot core. This solid core is as hot as the surface of Sun and its
size is about 80% of the moon. It is completely surrounded by a fluid outer core
consisting of melting iron. The speed of rotation is 0.2 % faster than Earth. This
friction creates the dynamo effect like Electric Motor and this effect generates
Magnetic Fields. Scientists call this as Hydro Magnetic Dynamo Effect. These invisible
geomagnetic lines stretch from one pole and out into space, then come back to the
opposite pole. This lines appears like a wire frame. Please see the
Figure 1.5,
1.6 & 1.7.
What is Magnetic North: Planet Earth produces Magnetic Field. We
need first distinguish between Geographical North and Magnetic North Pole. We need
also distinguish between Geographical South Pole and the Magnetic South Pole. Magnetic
North Pole is near the Geographical South Pole, Magnetic South Pole is near the
Geographical North Pole. Please see the Figure 1.3. Whether I am on North Pole or
South Pole it will not affect my compass. The Earth's magnetism is caused by the
flow of Electrons In its fluid metallic core, the fluid comes in perpetual motion
that’s why the earth magnetism varies with time. The move is quite gradual. Thus
the Earth may be visualized as a huge magnet. Magnetic poles moving, the change
in the location of the Magnetic North is known as Secular Variation. It is important
to note that, the location of Magnetic North Pole is affected also by Astronomical
Factors. This affects the magnetic compass reading. We measure our planet's magnetic
field (North) by means of magnetic needle. The source of this magnetic field is
at the Magnetic South Pole produced by the planet Earth near the Geographical North.
All our studies are based on longitude rather that latitude. Planet Earth produces
several poles, the most important being near the Geographical South Pole and North
Pole. Before the magnetic needle came into use, the Sun and the Pole Star were used
to determine the directions. However the magnetic needle doesn’t measures the Sun's
Pattern, it measures Earth's Magnetic Force. The magnetic needle is further more
not used in Vastu Shastra to measure apparent seasons or any climatic features.
Now the Magnetic North is near the Canada as shown in Figure 1.8.
Physical features
like Sun’s or Topographical Structures can also be used to determine directions
but in Vastu Shastra these do not determine the House Chart, which is always determined
by the magnetic orientation. If in Vastu Shastra we were to measure True North we
would not be measuring any source of Magnetic Energy. Also if we were to measure
True North, rather than Magnetic North, we would separate the magnetic field of
our human bodies from the magnetic effects of Magnetic North. In Vastu Shastra studies
we do not bother about the Solar Storm, what is happening on the other planets,
birth and death of the stars. The most important energies of the Earth are 1) Gravity
2) Magnetism 3) Solar Energy. Gravity is directed towards the center of the Earth.
This property is the most important character of the Earth Planet. While taking
directions and drawing it on a plane, we have to consider the center of the house
called as Centriod. Stand on this center of this house and we will observe all directions
around the house for studies.
