Answer: In the spiritual world, a person is composed both of a male and a female parts. The male part is the attribute of bestowal, which also has to be in a woman, and the female part is the attribute of reception, which has to be in a man as well.
The Creator is portrayed by the male since He has only one attribute: the attribute of bestowal. In relation to the Creator, all of us are like females, the feminine part.
