The number 21 is a deeply symbolic number that ultimately brings together the cosmic creation of the 20 with the individual – the one. Essentially the 21 is the manifestation resulting from the 20 in which the initiate must learn patience and develop a balanced mind.
We see this idea succinctly in the three and the seven, 7×3 of course equalling 21. The three is the sacred number of completion, the creation of the male and female energy and the symbolic meaning of the divine seven which determines whether the result is good or bad.
In the Bible, the 21 is associated with resurrection – death and rebirth. It is the end of one cycle and the beginning of a new mission. We see the same idea reflected in modern day traditions. When a person turns 21, they are said to have reached maturity and in the UK are given “the key of the door.”
In the Bible we see the 21 as a reflection of both good and bad. It is associated with sin and rebellion, but is also a representation of God and the Temple. There are 21 chapters in the book of Judges, a significant title given the 21 is when judgement is handed down.
