Hi everyone! In the book I'm planning to write, which is set in Ireland, there are some people who have magical abilities, and to cast spells and things like that they'd use some kind of energy (like the chakra, if you know what I mean

) Anyway, I thought of something like "flow", "flux" or "stream" to define this energy, because it kinda flows in these people. So I'd humbly ask you for the translation of these words or to suggest a more fitting term in Irish, if there is one. Thanks very much in advance.

P.S.: again, sorry if my English is bad sometimes ^^"
