Reiki Level 2 gives you an introduction on Reiki Symbols including the distance symbol. The distance symbol can be used to do Reiki on a person from a distance. This distance could be anywhere between a few miles to a few thousand miles. There is no limit to how far a Reiki Healer could be from the patient.
It is not important for the Reiki Master / Reiki Healer to know the patient personally. Some Reiki Masters / Reiki Healers prefer talking to the patient on the phone to get all details of the problem(s) the patient has, while some other Reiki Healers just do Reiki based on what information they have been provided by the patient, or by any other source.
Reiki Level 2 also gives you another Reiki Symbol that helps the healer heal problems related to the mind (Not the Physical Brain, but the mind).
Reiki Level 1 and Reiki Level 2 can be learnt in 2 days (and in some cases 1 day). However it is recommended that you learn one level first, then practice Reiki for some time and then move on to the next level.
We have put together some books that come with distant attunement. By going through these resources, you can learn Reiki from home. Visit our Reiki Books and Resources section to view these.
