Energy healer preparation is an important foundation for good energy healing. Whether you're doing it for yourself or for someone else, you should go into an energy healing relaxed, grounded, and in as elevated a state as you can be.
Quiet your mind and let go of your thoughts. Take a few moments to consciously work with your breath. Breathwork is one of the best overall ways to relax, ground, and center.

You want to go into a healing with the highest vibration you can manage. Of course, anyone serious about energy healing is on a long-term journey to develop their light body. But in the moments before doing a healing, you'll want to bring your vibration up to its highest potential at that moment. There are many ways to do that, but here are a few ideas. (I'm suggesting that you do one of these, not all!)
Think about something(s) that you are grateful for. Gratitude is an extremely powerful way to expand your energy, build your light body, and strengthen your connection to the rest of Being.
An attitude of gentle amusement and wonder usually promotes a light, high, fine vibration. Allow the corners of your lips and eyes to lift slightly. Allow yourself to "lighten up." Take a very high perspective and allow yourself to be amused at yourself and any worries or concerns you may have. Assume that all will be well. Adopt a sense of wonder, which does not require that you know the answer to all questions. Let a higher power be in charge, which allows you to get out of your own way, be more open to intuition, and be in a state of gentle enjoyment.
Both of these things open the heart chakra and nourish the light body.
Put a big smile on your face and keep it there for a while. Research has shown that your mood follows your body's lead. Smiling will help to shift your energy to a more positive state.
Spend a few moments in meditation or prayer, helping you step out of ego and connect to your higher self. Meditation helps to connect you to the source of all energy; prayer helps open you to the support of your higher powers.

An attitude of non-attachment to the exact outcome of the healing helps you to step out of your ego, which is limiting to the healing. Healing may show up in a different form or at a different time than expected. I've had clients leave with few apparent effects, only to call me the next day to report amazing results--more profound than any outcome I had imagined. Non-attachment to outcome allows you to just do the work, without worrying about your "performance."
Once you've done your energy healer preparation, you're ready to start your healing.
