Three are
the
circles of existence - light, chaos and awareness

The Gordian knot pendant shape
also known as the Torus knot,
can be made on a Torus tube which looks like a donut or a sphere. This
turns in from one side and comes out the other in a perpetual
motion. The Torus tube contains many mathematical formulas and
equations. Science began using this model as a geometric\mathematical
model of the universe. Sacred geometry also made extensive use of this
shape.

The Gordian knot is associated
in legend of Alexander
the Great:

Gordias made the knot. Seeing the intricacy of the knot, an oracle
declared that whoever succeeds in untying the rope knot would become
the king of Asia. In 333 BC, Alexander attempted to untie the knot.
When he couldn't find any end to the knot, he proceeded to slice it in
half with a stroke of his sword (the so-called "Alexandrian solution").

"Three are the circles of existence:

The circle of Light where dwells nothing but God and only God can
traverse it.

The circle of Chaos, from which all things by nature arise from death.

The Circle of awareness where all things spring from life."

Many people claim that after wearing the Gordian knot pendant during
the daytime,they had dreams in which they were able to solve difficult
"Karmatic" personal relations or situations. The reason for this is
that the pendant symbolizes the idea of unity, which transcends every
difficulty.

The Gordian knot pendant symbolizes the idea
of unity which binds everything into one.
