Today, the human body is already completely out of touch with Nature, and the powerful waves of the universe cannot express themselves through it. It is up to us to adjust the body again to the bosom of the blessed Mother Goddess of the World. It is up to us to cleanse this wonderful organism and prepare the body to become again a resonance box of Nature.
The disciple must invoke daily the Seven Powers with the powerful mantra MUERESIRANCA, begging them to prepare his body for the exercise of practical Magic. We should also be tenacious and persevering year after year, invoking daily the Seven Powers to prepare the body. The body of a mage has a different vibratory tonality from that of the other bodies of the human species.
