What was the philosophers stone called in ancient India and what was its compositional nature?
I believe it was known as the Chintamani Stone. This Chintamani Stone, which is of extra-terrestrial origin, had supposedly been brought to Earth by emissaries from a planet orbiting the star Sirius and then handed over to Shambhala’s principal resident, the elusive “King of the World,” a monarch known by many mystics in the East but only by a handful of occultists in the West. Apparently it green in color and is similar in appearance to a species of meteorite known as Moldavite, which is dark green in color.
