The Great Work, Healing, and Growth

Is personal 'healing', physical or emotional, a part of the Great Work?

The Great Work has many levels at which it operates. 
In the Microcosmic, it has to do with growth, expanding consciousness, the achievement of the Superior Individual, and Enlightenment.
In the Macrocosmic, it has to do with the spiritual evolution of humanity. There's much more teaching on this subject in Levels 2 and 3 of the curriculum.

As to 'healing' think of it like this: imagine there's a complex knot tied in a string, and that knot is in a tiny box (say, 2 inches by 2 inches).  The perspective most people have on "healing" is like trying to untie that knot in that tiny little box, because the knot occupies almost all of the space in the box.

Growth is where you expand that box, so the space is now 2 feet by 2 feet; or 2 yards by 2 yards, or 2 miles by 2 miles. So now, that knot that seemed so huge occupies just a tiny little space in the box. At that point, if it was necessary, the knot would be much easier to untie; but you might find that the knot is now so small that it won't really need to be untied at all, it can just be there, as one tiny part of the large space.
