Seven

The Seven Potters

Seven is the most powerful magical number, based on centuries of mythology, science, and mathematics.

Wizarding Community

The Arithmancer Bridget Wenlock, who lived from the year 1202–1285, was the first witch to establish the magical properties of the number seven.

Seven is the age by which most experts believe that magic will reveal itself in a wizard or witch. In the life of the Hogwarts School of Witchcraft and Wizardry community, it is the number of years students must attend Hogwarts before graduating. It is the number of Horcruxes created by Lord Voldemort, specifically because he believed in the numerological power of the number. Harry Potter and Neville Longbottom were born in July, the seventh month of the year; this made them both potential subjects of a prophecy. Arthur and Molly Weasley had seven children; Ginny Weasley is the seventh of them, and the only daughter. There are also seven players on a standard Quidditch team. During the Battle over Little Whinging, six others took Polyjuice Potion in order to take on Harry's appearance as a diversion, thus there were "seven Potters".

Magic and Mysticism

The number seven holds great power in the realms of magic and mysticism. In Judaism, the number seven alludes to the infusion of spirituality and Godliness. For example, traditionally it is held that "God rested on and sanctified the seventh day", or Sabbath. Seven blessings are recited under the chuppah during a Jewish wedding ceremony (Sheva Berachot). Moreover, there are the "Seven Shepherds" who visit the sukkah during the holiday of Sukkot: Abraham, Isaac, Jacob, Joseph, Moses, Aaron, and David. There were seven nations promised to the Israelites when they entered the land of Israel. The menorah holds seven candles.

The "Devil's Number" 6-6-6 is countered by the combination of 7-7-7 which is "God's Number". This number also joins together the principles of the man, 700, the cosmic plans, 70, and their image in the Archetype, 7, according to R. Allendy. It is the universal organization, 7 + 7 + 7 = 21, the general evolution.

Seven further has a presence in mysticism as Yahweh or Jehovah is the divine name in Christianity, whose letters alphabetically equal 70, a product of the divine number 7. There are traditionally seven virtues: Chastity, Moderation, Liberality, Charity, Meekness, Zeal, and Humility. Correspondingly, there are seven deadly sins and seven holy sacraments. According to some traditions, there are seven Archangels.

In Hindu tradition, there are seven worlds in the universe and seven chakras. In Japanese mythology, there are seven Lucky Gods.
