If I remember it correctly, either Carlos, or one of the witches, or perhaps Kylie explained in one of the early workshops in LA around 1996 (I just remember that someone explained it but I really can’t remember who of them did it, or at which workshop exactly, but I remember for sure that it was at the time when Carlos was still around) that this magical pass is called the life saver pass because it stabilises the gap the so-called tumblers (the rolling force) are constantly attacking until it finally opens when we die and our energetic structure dissolves.
