Hygiene is the first subject to consider in healing with the tips of the fingers. Hands that have been engaged in any work or that are stained with any liquid must be washed for healing. The healer must first observe the hygienic rules of keeping his body, as well as his clothes, pure and clean; especially at the time of healing he must be absolutely free from all that is unhygienic. The sleeves, at the time of healing, must be rolled back, and the finger-nails must be clean and properly trimmed.
