Yantra
Yantras supplement the power of mantras and are as strong as the
mantras themselves. If a mantra is the invisible driving force, the
yantra is the visible means to gain power and wealth, ward off evil
and illnesses, nullify the ill-effects of planets, bring you
luck in love & life, enhance your capabilities - and bless you
with almost any material comfort or spiritual benefit you desire.
Yantra
is an instrument, apparatus, a talisman or a mystical diagram. It is
a technique or path, considered the simplest and shortest, thru'
which one can attain one's desires, and fulfill one's wishes. It is
said that the 'Devas' or Deities reside in the Yantras and by
performing 'Puja' or worship of Yantras, one can appease the
Deities, remove the malefic effects of planets, and increase the
flow of positive influences.
Yantras are sometimes made up of numbers,
or a certain set
of symbols, or mantras. They can be written on paper or
bhojpatras (parchment) and worn as talisman; they can be engraved
on an amulet or pendant and worn on the body; they can be painted on
a door or wall or the floor, they can be engraved on gold, silver,
copper, iron and even painted on leaves, stones and other objects.
The
writing, painting, engraving or whatever other form of transference
which is employed must be done according to a specified set of
rules. For instance, certain Yantras can only be made on certain
days, at a certain time. Similarly, there is a distinct link between
the kind of Yantra and the kind of metal chosen. For example, a
Yantra to appease the ill-effects of the planet Saturn is generally
engraved on iron - the metal associated with Saturn. The Yantras
written, drawn or painted on paper, bhojpatra or leaves, must use
the inks specified by ancient texts, such as those made from red
sandalwood, or saffron or white sandalwood, etc. The type of pen,
its length, width, etc, used for preparing a Yantra varies according
to the purpose and type of Yantra. Whether on paper or any other
material, the size of the Yantra is also pre-specified, as is the
duration for which its efficacy will last. Then again, the Yantras
must be installed in a certain manner, on a certain day, at a
certain time, facing a certain direction and must be sanctified by a
specific mantra begun on a certain day and time, recited for a
specific number of times. There are various other rules also. A
particular Yantra must be washed in the specified manner, for
example, in milk and water. Unless a Yantra is worn or installed
according to the rules, its efficacy is greatly reduced and the
effects virtually diminish.
Some
of the earliest Yantras are associated with auspicious symbols and
powerful numbers. In ancient India, for instance, the good luck
square of nine which always added upto fifteen was deemed a
harbinger of prosperity and happiness and even today some business
establishments and even homes paint this square near
their main entrance.
