You have, besides your physical body, more spiritual layers or ‘bodies’. The energetic body, also called live force body or etheric body. The soul, or astral body. And the spirit, also called Higher Self.

The physical body is all the minerals, who don’t do anything on their own. They need the energetic body for that. Plants have a physical body, as well as an energetic body. Stone, sand, minerals only have a physical body.
In the energetic body there are our needs for basic food, water and air. There’s also our pain experience, our long-term memory, our basic habits. When healthy, the energetic body is slightly bigger then our physical body. Most inflammations are from misalignment of our energetic body, caused by:

The soul. The soul is the next layer of our spiritual bodies. When people talk about aura, most of it is our soul. In it is our daily self or ego, our consciousness, our emotions, thoughts and perception of the world. It’s bigger then our body, when healthy it’s an oval shape around us. Our emotions and thoughts aren’t just in our body, they are also around our body.
It’s also called our astral body, but as far as I understand, our soul is transformed astral body. We develop ourselves, and in that proces, we refine the astral body into soul. The anthroposophy mentions the perception soul, the emotion/thought soul and the consciousness soul* as three different layers.
The soul wants a lot of things and where it’s not refined (the astral part) it pulls on our energetic body and tires it. When this is too much on certain parts of the energetic body, it gets misaligned and the physical body gets ill. (shorthand)

Last layer is the Spirit, also called Higher Self, or “I”. I try to use the term Higher Self, because, as far as I understand, spirit in English might be confusing, while it’s also used for more things. The Higher Self has your deeper ideals and plans, it can oversee (in a sort of dreamlike consciousness) the different lives, most of them in the past and somewhat in the future. It’s the driving force in the transformation of the soul and energetic body.
It’s the central part that goes from live to live through reincarnation, shedding the energetic body and separating and rejoining with the soul for each incarnation.
And it’s our Higher Self, where as our soul is our daily, ‘lower’ self, which can be egoistic and therefore houses the ego.

*perception soul, the emotion/thought soul and the consciousness soul are my translations of the Dutch translation of the German text. So it may be different from the main use in Occult Science and Theosophy from Rudolf Steiner.
