All mystery is hidden in name. The knowledge of everything rests on first knowing its name, and knowledge is not complete which is devoid of name. Mastery depends upon knowledge; man cannot master a thing of which he has no knowledge. All blessings and benefits derived from earth or heaven are gained by mastery which depends upon knowledge, knowledge depending upon name. Man without the knowledge of the name of a thing is ignorant, and the ignorant is powerless, for man has no hold over any thing of which he has no knowledge.
