The soul never actually left the collective soul; it simply stopped feeling it, since it corrupted its spiritual feelings by acquiring an egoistical desire. But in the process of desiring correction, the soul corrects its feeling and becomes able to feel its true state in the collective soul.
Retrieving this feeling is called “the ascent up the steps of the spiritual ladder” from our world into the world of Atzilut.
