True healers know that wellness is the order of the day, so they do not allow themselves, even for a moment, to see anything other than that. So, the power of the healer is in the power to influence the one who needs to be healed into a vibration that allows the healing that they are summoning. (that they could get, even without the healer, but they can get faster with a healer's influence)
