Life style is related to health and wellness, and learning to observe one's habits, tendencies and intentions can be a place to begin a deeper form of self care. The external body is our personal 3-D material expression, and as such, holds pathways to understanding ourselves, as both a starting point and a way to work inwards.
The internal body is also in a material form, but is felt rather than visually seen, and so it expresses a different form of self contact, one that is seen and experienced through feeling.
