Hi Amir

Congratulations for Usui reiki level one .

It's great chance to receive reiki initiation from wonderful friends like Bjorn and Alina.

Ramazan begins on 11 august, a few days left for holy month. As you know, fasting is done for purifying body and soul. It's a religious definition, ramazan is time of worshipping God.
Reiki also purifies body and soul. It's not religious. It's universal life force, a healing energy contains light,love and wisdom.
Similarly two of them provide detoxification for whole being of one.
So you can perform self-healing after Iftar. Or if you want and if it's not difficulty during fasting, you can do self healing during day while you are fasting. You know that some people may not want to perform reiki during religious acts, worshipping. I respect each ideas, they are all personal.
I prefer to do healing seance after two hours of Iftar because of digestion. Also it helps for body regeneration and health of immune and other body systems for me after all day hunger and thirsty. It makes me feel uplifted. I haven't ever experienced any detoxification problem on last ramazan months.
It's up to you and up to what you feel.
If you feel uncomfortable on detoxification period in ramazan (I don't think but maybe if it happens) ,then you can delay healing seances after ramazan. Please follow your senses and intuitions, trust your inner voice

Many Blessings..
