Learn why seven is a magical number.
In magical lore and mysticism, seven is a magical number, though all numbers are ascribed certain properties and energies. Seven is a number of great power, a lucky number, a number of psychic and mystical powers, of secrecy and the search for inner truth.
The origin of seven's power lies in the lunar cycle. Each of the moon's four phases lasts about seven days. The Sumerians, who based their calendar on the moon, gave the week seven days and declared the seventh and last day of each week to be uncanny. Life cycles on earth also have phases demarcated by seven, and there are seven years to each stage of human growth, seven colors to the rainbow, seven notes in the musical scale, seven petitions in the Lord's Prayer, and seven deadly sins.
The seventh son of a seventh son is born with formidable magical and psychic powers, it is said. The number seven is widely held to be a lucky number, especially in matters of love and money.
