TRADITIONAL USE AND DESCRIPTION
This instrument displays the local meridian and the
directional move of the sky and is a complementary instrument
to the Samrat Yantra.
This instrument has two vertical walls parallel to each other
that are aligned directly north--south, parallel with the plane
of the local meridian. The eastern and western sides of this
instrument contain two instruments for measuring the altitude
of the Sun at solar noon (when the Sun is highest in the sky).
As the Sun passes the meridian directly overhead, a shadow is
cast by the pegs along the entire length of the wall. Simply
by noting where the shadow crosses the scale, one can determine
the altitude of the Sun. The markings in the hollow space follow
the movement of the Sun's shadow one degree at a time as the
Sun approaches and passes solar noon and also indicate the rising
Zodiac Sign of the Sun.
VEDIC INFLUENCE--THE VIEW OF MAHARISHI VEDIC SCIENCESM
Viewing this instrument aligns the thalamus1 with three times of the day: horizontally
at the rising time of the Sun, vertically at solar noon when
the Sun is directly overhead, and again horizontally at sunset.
The precision of the Sun, displayed at those times of the day,
is instilled and enlivened in the thalamus through viewing this
instrument. The process of observing this instrument is said
to remove or disallow any influence that may shadow this direct
connection between the thalamus and its cosmic counterpart, the
Sun. It moves the individual into more complete coordination
with the Sun and its all-nourishing value to life.
