Hello!

I am a Reiki Master (but not already Teacher) since a few weeks now.
There is something which I do not understand with Reiki attunements because I got pieces of information which I find contradictory.
The Reiki attunement can be given when the student asks for it and feels ready. A 21-day period of time should be respected between two attunements.
But:
1. It is also possible not to respect this 21-day period of time
2. No matter if the attunement is for Level I, II or III, the way you proceed (as a Teacher) is always the same
3. You can give one or several attunements for each level
What I do not understand is:
If the way you proceed for each attunement is the same, and that someone can be attuned for several levels within less than 21 days, how is it possible to give several attunements for one level?
In other words, what is the difference between those 2 cases:
- you are giving an attunements for Level I and the day after a second attunements for Level I
- you are giving an attunements for Level I and the day after an attunements for Level II
In my case, I had a 2-day course where I got 4 attunements for Level I. But my Reiki Master would have proceeded the same if she had wanted to attune me in Levels I and II... So where is the difference?
Does it depend on the Master's intention to attune in a certain Level or does it depend on the student's preparation?
I hope this is clear...
Many thanks in advance for helping me and giving me your point of view!!
