The Beings of Light from Sirius participate in the Ascension Healing Course to facilitate the development of Christ Consciousness in the participants. These masters come from the star Sirius A, located in the constellation of Big Dog, which is about 23 times brighter than our Sun and lies at a distance of 8.6 light-years (about 8.136 x 1013 Kms) from Earth being the brightest star that can be seen in the night sky. The star Sirius α (Alpha Sirius) forms with the star Sirius β (Beta Sirius), a binary of stars that orbit each other separated by a distance of 20 astronomical units (about 3 000 000 000 Kms).

The name Sirius comes from the Greek seirious meaning “bright”. This is a star worshipped since ancient times by various cultures on Earth. For example, Atlantis in the language spoken by the ancient Atlanteans means “The house of Sirius”. This fact already indicates the connection of the Atlantean civilization to the Sirian masters who transmitted knowledge to them. This knowledge, when Atlantis sank, passed to Egypt where the star Sirius became associated with the goddess Isis (currently an ascended master and female complement of master Serapis Bey – the god Osiris).
