Here is one of the Kundalini Reiki healing techniques:
1. place your hands close together, palm facing up.
2. Visualize the person's name that you're going to heal on your palm.
3. Close your palms
4. Chant "Reiki" (use "Kundalini Reiki" when level 2) to get the energy flowing.
5. Enjoy the energy flow and that's it
It is also uneccessary for you to focus on which point of the pain is on the recipient, because in Reiki Tummo, your energy is like water being poured on a pit with potholes - they still get filled anyway, which means the energy knows where to go to fix the problem.
