The six pointed star is formed by the downward pointing triangle merged with an upward pointing triangle. The triangles representing the duality of masculine and feminine energies, creativity, Yin and Yang, Shiva and Shakti energy.
Where the two triangles intersect this represents the centre point where the two forces of duality, Yin and Yang, matter and spirit energies balance and merge and commune and is the balance of harmony and wholeness. The elements of fire and water are combined. They are the depiction of "as above, so below" as well known in metaphysical edicts. Six is equilibrium and harmony.
