How long does Reiki take to learn?

Reiki consists of three levels of training known as 'Reiki 1', 'Reiki 2', and 'Reiki Master' or 'Reiki 3'.

These levels can be "learned" over a period of many months or years, or can be taken over one intensive period.

It really depends on the individual wishing to "take" Reiki.

If you feel more comfortable taking your time "learning" Reiki, then do so. If you think you are ready to "take" all three levels in one go, then you are ready.

It's entierly up to you.
