Reiki Levels
Reiki First LevelThe Reiki First Level (First Degree Reiki) is the starting point in the Reiki system -- it's the entry level. In the first level of Reiki, the Reiki Master will give you the attunement.
The Reiki Symbols are placed in your Aura and Chakras, but they are not revealed to you.
The Attunement will permanently open your Crown Chakra, the "third eye," throat, and heart Chakra so that you will be able to channel Reiki. At this level, you will be able to heal yourself, family, friends, pets, etc.
Reiki Second LevelThe second step is Reiki Second Level (Second Degree Reiki) and a Reiki Master gives the Attunement once the student has received the First Level Attunement. During the Attunement, the student is attuned to the first three Reiki Symbols which enables them to use them in their healing. The Symbols give the Healer many options, including increasing the strength of the Reiki, helping with mental and emotional issues, and the ability to send Reiki over time and space (long distance healing) to any person or situation for healing.
You can take this second Attunement when you feel you are ready. Some people take the second within days of receiving the first Attunement so they will have the benefit of using the Reiki Symbols.
Reiki MasterThe final step (Attunement) is the Master Level (third degree). This Attunement empowers you with a Reiki Master Symbol and gives the ability to pass all the Attunements to other students and be a Reiki Teacher. It also increases your Reiki Healing and opens up your third eye.
You are ready for the Master Attunement once you have received the first two level Attunements and you are ready to take on the responsibility of being a Reiki Master.
