Sacred fire of the Sun
"The sun is living fire, and it is by going to see the sun rise every morning that we renew our contact with this fire from heaven. If you, with all you heart and the powers of your intelligence forge a close bond with the sun, you allow the sun to set you on fire and flames will begin to rise and enfold you. The Holy Spirit is none other than the sacred fire of the sun."
Quote from the book 'The Splendour of Tiphereth"
