What is the Sapphire Sisterhood?

This term is from the “Invocation of the Illuminati” found in the Seven Sacred Seals & Portals to Grace

The Great Sapphire Sisterhood is the counterpart to the Great White Brotherhood – both expressions refer to circles of initiates and masters who have ascended through the earth plane and exist as celestial beings or synarchies where their Gifts and Siddhis are fully manifested as a collective field of intelligence. These two synarchies represent both Divine Masculine and Divine Feminine poles.
