Number correspondences and numerology are just pieces of a larger belief, common to most cultures, that seemingly unconnected things share a mystical connection. Tables and lists of correspondences are very old and not limited to books on spellcasting. Gnostic books in the Nag Hammadi Library contain lists of aeons and archons (good and evil beings) that correlate them with or associate them to various virtues and vices. Medieval grimoires included lists of correspondences.
1 - One is the number of essence. It is the symbol of identity, of equality, of existence, of conservation and of general harmony. Being without parts, a single unit announces order, peace and tranquility, which are founded on a unity of sentiments; consequently, one is a good principle. One represents new beginnings, new happenings, new potentials, self-completeness, beginnings, creativity, the individual and the positive.
2 - The number two is the origin of contrasts, it is the symbol of diversity, of inequality, of division and of separation. Two is an evil principle, a number of bad omens, characterizing disorder, confusion and change. Two represents balances, a balance of energy, gentleness, nature, imagination, romance, couples and love.
3 - Three is the first unequal; it is the number containing the most sublime mysteries, for everything is composed of three substances. It represents divinity, the soul of the world, the spirit of man. It is meditation, atonement, completeness--beginning, middle and end. Three represents creativity, activity, results, ambition, control and authority over others and moving forward.
4 - Four, the first mathematical power, is also one of the chief elements. It represents the generating virtue, from which come all combinations; it is the perfect of numbers; it is the root of all things. This number gives the human soul its eternal nature. Four represents foundation, building, structure, stability, rest and health.
5 - The number five has a peculiar force in sacred explanations: it is everything; it stops the power of poisons, and renders evil spirits powerless. Five represents action, energy, conflict, opposition, versatility, communication and impulsiveness.
6 - Six is a fortunate number, the number of luck and chance. It derives its merit from the first sculptors having divided the face into six portions. Six represents kindness, luxury, love, friendship, money, art, affection and health.
7 - Seven is a number very powerful for good or for evil. It is the number of the entire cosmos. Seven especially belongs to sacred things. Seven represents spirituality, mysticism, imagination, psychic power, secrets, travel, change, intuition and clairvoyance.
8 - The number eight is the first cube, that is to say, squared in all senses, as a die, proceeding from its base two, an even number. Eight represents strength, perfection, karma, stability, intensity, strength, loneliness, hidden feelings, secrets, institutions, hospitals, health and long term illnesses.
9 - The square of three being nine, nine is regarded as the extent to which numbers would go with all others being embraced and revolving within it. Ten but recommences a fresh series capable of infinite expansion. Nine is regarded as sacred and represents fruition, accomplishment, courage, completion, high spirituality and is a good number to incorporate in all spells.
