I came to set fire to the earth. And I am watchful that the fire grow.May the fire of love grow in our hearts. May the fire of transformation glow in our movements. May the fire of purification burn away our sins. May the fire of justice guide our steps. May the fire of wisdom illuminate our paths. May the fire that spreads over the Earth never be extinguished.
