The universe was created by two principles – the masculine principle and the feminine principle – and it can only subsist through the work of both these principles. Contained within the number 2 are all the possibilities for creation, but so too are all the possibilities for division, and as such, confrontation.
The number 2 is also the beginning of what is called evil, which is why it is said that 2 is the number of initiation. All the deepest, most complex, most dangerous questions are contained within the number 2.
It even harbours the secret of the existence of the so-called devil always described as an entity that rears up against God, declaring himself as his adversary.
In reality, God has no adversary.
Since he is the 1, he is beyond good and evil. God is not only the good, he is also not opposed to the devil, the embodiment of evil and whom he cannot defeat.
Both good and evil are his servants.
