When a thing is quadrupled it is made four times as large or four times as important as previously. In spiritual terms this suggests that there is four times the amount of power available – it is power ‘squared’.
Psychological / emotional perspective: The symbolic meaning of number four deals with stability and invokes the ability of all things to be grounded, so anything that is quadrupled is linked to the proper manifestation in the physical realm. Things must manifest through the four elements of fire, air, water and earth to become real.
Material aspects: As we become more aware, the ancient symbolisms become more relevant. Anything which is represented as being quadrupled in size or power picks up on the symbolism of numbers. Fours represent solidity, calmness and home in the sense of sanctuary. On a mundane level, this means we may need to consider our need for security. Consult the entries for elements and numbers.
