Reiki attunement 1 is the first step to become a healer. The process takes about 15 minutes and conducted by a master. In some schools like Chikara Reiki, the process could be done by self attunement.

Reiki attunement process used to be a heavily guarded secret in the past, and only passed in person to the best students. Now, with the changes in technology and communication, you could actually find a reiki manual online. Like any other information on line, you have to be very selective and careful in selecting any information, including reiki manual. It is better to get an attunement from a master that has good reputation. You could check forums or check around with your friends.
