The final level within this stage is coming to love God greatly, comparable to a glutton who becomes infatuated with a material pleasure, such that thoughts of that pleasure stand before his eyes all day and all night. This is what the poet stated: “When I recall Him, I cannot sleep” (Seliḥot for the second day of the Ten Days of Teshuva). The verse also states: “Fulfilled desire is a Tree of Life” (Prov. 13:12). For the five levels of the soul [Nefesh, Ruaḥ, Neshama, Ḥaya, and Yeḥida, referred to by the abbreviation NaRaNḤaY] are the secret of the Tree of Life, which lasts for five hundred years. Each level is one hundred years. During this time, he can receive all five aspects of the soul. (The five levels will be explained shortly, regarding the third stage.)
