Tacyon Reiki is a popular system originated with Ole Gabrielsen.  With Tacyon you can use any material you wish, such as a stone to construct a Tacyon antenna (through intention) in which energy flows through 24 hours a day. 

The Great Central Sun attunement adds a component to this system allowing you create a different kind of antenna in addition to the original Tacyon one which is more powerful for channelling.

You need to have been attuned to Tacyon Reiki before you receive this attunement; both courses are available below as a package for those who have no experience of Tacyon yet though!
