Every Jewish soul starts off in a state of total unity with G-d: 

The Jewish people as a whole are referred to in Scripture as 600,000 feet of the nation. This comes to hint to the idea that the Jewish people are the children of G-d, and a child is the extension of his father, acting as his leg. Just as a leg is nullified to the head and does everything the head wishes, so too the son. Every Jewish soul contains a naturally born feeling of nullification to G-d which is expressed in the hidden love that is contained in the heart of every single Jew and is above rhyme or reason and is expressed as the natural attraction and love that a son has for his father. Originally, a son was included in his father’s intellect and considered one with him. It is only afterwards through conception and birth that he has become his own independent entity. The same applies with the soul. In its origin, the G-dly soul is much higher than the level of foot, as it was one with G-d and was actual G-dliness. However, after the soul descends through the chain order of the world it becomes its own entity and is now called a leg. Nonetheless, it maintains the aspect of being a leg of the father and therefore still contains nullification due to their root. Furthermore, even after its descent below the soul maintains a relationship with its root above which is the level of Mazal. Every single Jewish soul contains a Mazal up above in the world of Atzilus which experiences G-d and sends messages to the soul below.
