It could be a tenet of Wicca (but it's not, since Wicca tends toward tenetlessness) that Witches Heal. Though we often speak as though healing is something we do for another person, as in a doctor healing her patient, in fact we can only heal ourselves. I can care for another person and provide some conditions for healing, but only he heals himself. Similarly, and of concern to many Pagans, we cannot heal the earth; but we can care for the earth and provide conditions under which it will thrive and heal itself.
One of the most important things we can do as healers is to bear witness: to hold a non-judgmental but discerning space for the person or being who is healing. We need to be able to discern what would help them (an action, a holding, a medicine, a clean needle, a kind word, a pointed observation, a touch), but we cannot sit in judgment, for judgment limits and constrains where healing needs room for natural expansion and contraction. Bearing witness means being able to see things as they are, not as we wish they would be, and to "hold space" compassionately for whatever arises. Much of the work of a healer lies in being present to another, not buffeted by or frightened by their emotions, not sucked in, not closed down, not colluding, not withholding. Being with. And in that being, seeing what else might be needed.
