A certificate of attunement confirms that you have received the attunement directly from me and are able to energetically pass on the attunement if you so wish.
The certificate of attunement does not in any way infer professional training, teaching ability, mastership, qualification etc.
The certificate of attunement includes the name of the attunement, lineage (me and you), date and my signature.
If you work with lots of attunements, it may be helpful to create a spreadsheet that tracks the attunements you have accepted.
It should be noted that if you do want to pass on, teach or resell any attunements created by Blissful Light, you will be bound by the Resell and Copyright Terms.
