Diamond World Mandala comprises not one, but nine different Mandalas,
which are called "The nine Assemblies", using the word "assembly"
to translate mandala.
eight mandalas surrounding the the central "Pefected Body Mandala"
are its various aspects, so that the painting at the whole shows nine
variations on the form of the Diamond World, which is the Dharma Body
of Mahavairocabna Tathagata.
