"The Initiate must descend into the infernal worlds for forty-days and has to recapitulate all of the evil deeds and frightful dramas of his past incarnations; little by little, the Initiate departs from these tenebrous regions. Before departing, the three souls (Nephesh, Ruach and Neshamah) are submitted to ordeals. How interesting it is to see the animal soul submitted to ordeals, as well as the thinking soul and the Essence (fraction of Neshamah) that also is submitted to ordeals." - Samael Aun Weor
