If knowledge and wisdom keep the same pace in development, the adept is enabled to grasp all the laws of the microcosm and the microcosm, not only from the point of view of wisdom, but also from the intellectual side, that is, in a bipolar way, to perceive and utilize them for his own development.
Franz BardonThe activities and effects of the Fire and Air elements in the astral sphere call forth the astral-electric fluid, and the activities and effects of the Water and Earth elements call forth the astral-magnetic fluid. The spirit-beings use these fluids to create the effects or rather the causes in our physical world. The Akasha Principle of the astral sphere maintains the harmonious equilibrium of the elements in the entire astral sphere.
Franz Bardon... All these preparations clearly show that a human being must perfect himself in the physical world through his magical development in order to be prepared for the higher astral world after death.
Franz BardonVegetarianism is not implicitly important for the mental progress or the intellectual development, unless it is supposed to be a remedy to clean the body from slag. A temporary abstinence from meat or animal food is indicated only for very specific magic operations as a sort of preparation, and even then only for a certain period. All this is to be considered with respect to sexual life.
