"Because there is a link between what is above and what is below, be aware that every impulse from your higher nature may provoke a reaction from your lower nature, which will do all it can to make you abandon your good intentions. These tricks of the lower nature prove unsuccessful in the disciple who has made a habit of analysing himself and who remains vigilant, for while he works, meditates and builds on the spiritual plane, he attracts and surrounds himself with invisible beings who watch over him and protect him.

In early freemasonry, which was based on a true science, the mason was portrayed at work with a trowel in one hand and a sword for self-defence in the other. The mason symbolizes the disciple: while he builds, another being within him, represented by the sword, keeps watch and projects a beam of light. He is thus assured that certain enemies do not slip in under cover of darkness and destroy his work."
