This is the third part or the series "The Arcane Teaching" (the other two are "The Arcane Teaching" and "The Arcane Formulas".In this, the author analyzes VRIL, the universal principle of vital-energy, life-force, or vital magnetism, as it is sometimes called.In many of the ancient occult treatises we find frequent reference to "Vril" not only in its sense of the principle vital energy, but also that sense of inherent usable energy which we seek to express the term "human magnetism".
