According to the Hebrew tradition, Lilith was Adam's first wife. Both were created from the ground. This theory probably has its roots in the interpretation of the Book of Existence (Book of Genesis) and a twofold explanation.
According to Genesis 2:22, "God created Eve from Adam's rib, or in one of the preceding paragraphs, more precisely 1:27, points out that women already created:" And God created man in his forms, according to forms of God created he it; male and female he created them. That was Lilith. Before Eve.
Also according to Hebrew tradition, Lilith was banished from paradise when she refused to obey Adam, especially after sexual intercourse, because she refused missionary position, or to be "under him."
When she was expelled from paradise turned into a demonic figure and Adam assigned new wife, Eva, who was created from his rib because Adam wanted her obedience. Clearer explanation for her refusal to obey should be emphasized in order to better understand the myth.
She requested from Adam to perform sex act "on the side" or that she was "up". He refused. Then she became a demon by getting expelled from paradise and so she began to communicate with other demons and gives birth to their children. So her only mistake was that she demanded equality.
What exactly Lilith symbolizes in the birth chart? Symbolizes the dark side of our nature, what is hidden even from ourselves. Our partnerships, our fears, psychic stability, sexuality also our wishes, fantasies, frustrations but also our limitations.
Furthermore, the lessons we need to learn the in hard way, sacrifices that we have to experience. It is the point through which the "Force Majeure" enters into our lives and shapes our spirit.
Aspects to Lilith built in Natal chart are very important and orbits (distance) must not exceed 2 degrees. Conjunctions are naturally the strongest. The sign in which Lilith is, describe pattern by which it will be manifested in our life.
The house where Lilith is in the natal chart will describe through which power will act.
