Can I attune myself once more, if that's the case what occurs? 

You possibly can all the time re-attune your self at any degree or undergo all of the Initiations once more. It's prompt to take a look at your self in mirror as you do every Initiation as this appears to boost the impact. 

You don’t have to re-attune your self to any ranges as uou are already a Grasp of Reiki and Seichim however it's OK to say re-attune your self to Reiki Degree I once more to expertise/Grasp the Initiation phases as you might wish to “practise” earlier than coaching others into Reiki. 

Once more all it does is improve and make clear the Reiki energies you obtain, you don’t unfastened your Grasp degree initiations, no matter what re- attunements you might be doing, as they're there for Life!
