First, treat yourself. You are a channel of Reiki, and you can be in as perfect health as your ego will allow you to express.
Next, treat family members. Normally, the family unit will have provided you with many benefits, and transmitting the health of Reiki is an excellent way to complete the exchange.
Third, consider treating anyone who asks. Asking is important. Because Reiki is a system based on intention, the prospective client should express their intention for health by requesting the treatment.
Naturally, if the person is in a coma, or is an infant, or someone whose family asks for the healing, or someone for whom you are responsible, it is appropriate to do Reiki.
By stating in your mind, “you are free to accept or reject this healing as you will”, you acknowledge the will of the client, and do not impose your will on them.
Be cautious in treating an accident victim you don’t know, as it is legally advisable not to say anything about your healing ability.
“Reiki simply works wonderfully on babies,” affirms Samdahl, enthusiastically. “They have no barriers whatsoever. They are completely open to God’s Love. And that’s what healing is: God loving us.”
Hospitalized persons, or those under conventional medical care, can also be treated with Reiki. Do not diagnose illnesses or prescribe medications, however, unless you are an M.D. Suggest, rather than direct: simply state what you would do if you perceived the condition, giving the patient the responsibility to assess its merits for themselves. It is also important to remember that you should never feel forced or obligated to heal someone, or guilty for not taking the time to heal whenever or wherever requested.
One is never tired or depleted after giving a treatment, as we are using universal life energy, not our own.
Therefore, you can consider applying Reiki in some rather unorthodox healing situations. What to treat can become as vital a consideration as who to treat.
