Our understanding of healing is sometimes such as wanting to avoid anything that creates pain or suffering. Well, this is indeed very pragmatic but sometimes blocking, if this desire is based on fear.
Further we might consider healing to mean, that we have to fulfill social norms by e.g. having a predefined body weight, or by our tooth color meeting the expectations, or our teeth being in a certain positon, or our skin color being the required one etc. etc.
Long story short, our perception of healing might well be distorted and we are disappointed if healing does not come along how we imagined it to be with our conditioned manipulated understanding of it.
Perhaps healing is happening on a totally different level, one we have not thought of from our limited point of view. As an example, a crooked tooth might be part of an ideal body static.
Hence, healing might be, among other things, to heal our understanding of healing. This might save a lot of disappointment and enables us to be a lot more open and to have less expectations.
Maybe a setback is needed in order to achieve divine order. Although we might be disappointed at first. Anyway, time and again let us remember to ask for divine order, let go of our fear and accept what shows up.
Of course a certain expectation is useful, but in a way that leaves
space for surprises and unexpected results, some we would probably
never imagine from our current point of view. Thus, healing can, among
other things, be seen as a question of perspective and trusting in
life.
