Esoteric Lessons II
The physical and etheric bodies are closely connected in an ordinary man. Whether he raises a hand or thinks, when he uses his physical body he also sets the corresponding part of the etheric body in motion. This connection should become looser in an esoteric.
A man has a backbone that's connected with the brain and sense organs. When he meditates, he creates a kind of a “forebone” in his etheric body; that's the row of lotus flowers that lies behind the breastbone.
The loosening of the physical and etheric bodies enables a man to heal wounds faster. Diseases of the physical body that remained concealed while the close connection was there, can then appear. One shouldn't pay much attention to small pains and ailments, because they're all transitory. But one can feel very uncomfortable when this loosening begins. Theosophical study already brings about this loosening, whereas scientific training makes the connection between the physical and etheric bodies even tighter.
So through meditation the etheric body gets the tendency to become separated from the physical body. One can intensify this through a suitable diet. Diets give the physical body the tendency to push out the etheric body. This is an aid that however brings about the wrong thing if esoteric exercises aren't added. Then the physical body ejects the etheric body without developed sense organs Then it's like a blind man, and it only sees its own daydreams.
While a man's sheaths undergo a change in this way, his connection with the macrocosm also changes. This connection must be cultivated in the right way, otherwise disasters occur in the whole world, and not just in man. For instance, someone who would utter the sacred, unspeakable name in an unsuitable group would conjure up something worse than earthquakes and volcanic eruptions over the region. Therefore, it makes a big difference how the Rosicrucian verse is spoken, namely with or without the name that's just pseudonym for the highest spiritual being. Only the latter way of speaking the verse is an esoteric one.
