Theres many level from a physical person to a total Spiritual angel
1)Human Ruach Hakodesh
2)Human Navi-Prophecy
3)Demons (between humans & angels but not animals)
4)Angels-fully spiritual
many other levels between each of the above to reach a full complete spiritual person free of Physicality of this world (you don’t need to be an Angel to remove physicality from you.
ex.you can have a good steak & it can be pure spiritual with your only intention being to have strength to serve Hashem)
