What is Reiki?
Reiki is a gentle, hands-on, Japanese healing practice and system. It is similar to Healing Touch or laying on of hands. It is not massage. Reiki is a very gentle energy that you must experience to fully understand. Some people feel heat or warmth, slight tingling or even coolness coming from the practitioner's hands. Reiki rebalances your energy so your immune system can kick in and you can heal yourself.
Reiki Level II
This class is for people that have completed Level I Reiki. In this class you will continue on your healing path with Reiki and continue your work with animals. The focus of this class is on more advanced meditations and Reiki practices. This course is unique because we focus on both humans and animals.
Day 1 Participants will receive the three level II attunements and will be taught three Reiki symbols and their mantras. Building on what was learned in Level I, students will learn more exercises to help increase the flow and level of energy in themselves. We will practice group energy healing, long distance healing and much more. Students receive the level II manual.
Day 2 Students will learn how to send long distance Reiki to animals as well as continue their practice and experience with in person Reiki with animals. Level II students will develop their intuition when working with Reiki. Upon completion of day two students will receive the Level II Reiki practitioner certificate.
