Space is not something vague and undefined. It is subject to a structure which corresponds to the number 4: the four cardinal points. But what are the four cardinal points other than a cross? When initiates are about to start a work, they turn successively to each of the four directions in space, thereby drawing a cross, indicating that their spirit is about to start work. Each of the four cardinal points is presided over by an archangel: Michael for the east, Gabriel for the west, Uriel for the north and Raphael for the south. Since initiates understand the living cross, all the light beings respond to their call and come to participate in their work.
This ritual of turning towards the four cardinal points has been perpetuated in the Christian religion in the form of the ‘sign of the cross’. When Christians move their right hand from their forehead, to their solar plexus, and then to their left shoulder, then their right shoulder (or vice-versa, to their right shoulder and then their left shoulder) while saying, ‘In the name of the Father, the Son and the Holy Spirit, Amen’, they contact the four directions in space. Space is the matter on which they work thanks to their presence and love.
