The Flame of God is the Human Soul

Come and see: Nefesh is the lower animation that is attached to the body, like the light of a flame, where its lower black light is attached to the wick and is not separated from it and is only repaired in it. And when the black light is repaired and held on to by the wick it becomes a throne for the upper white light which is upon it, for it dwells upon the black light. And this white light corresponds to the light of the Ruach.

After the two of them are repaired, the black light and the white light which is upon it, the white light becomes a throne for the hidden light which is unseen and unknown, which dwells on the white light and this corresponds to the light of the Neshama, and then it is a complete light. In the way that there are three lights within a flame, one on top of the other: 1) Black light attached to the wick, which is the lowest of all, 2) White light which dwells upon the black light, 3) Hidden light which is unknown, that dwells upon the white light. Thus it is with a person who is complete in everything, who has also three lights, one on top of the other, as described above with the light of the flame, which are Nefesh Ruach Neshama. And then this person is called holy, as the verse says: "As to the holy and mighty ones that are in the land ..." (Psalm 16:3).
