There is nothing evil about Reiki that I am aware of. … Now if they claim it comes from somewhere else then there might be a reason to be concerned.

You call yourself a Catholic?! How can you say that this is of God?! It is NOT from God. Someone practicing Reiki opens himself up to Satan whether he believes it or not.
You do have reason to be concerned. Please read the quotes that I have from certain Catholic websites below in this post.
Do you believe in Buddhism? If you are Catholic then you should not believe in Buddhism nor in any of their practices. Reiki is from Buddhism.
Here is web site that might help clarify it,…
And those “Christian Reiki” websites are just the devil trying to get in by means of the name “Christian” just to fool you. So don’t let the devil fool you.
Many nursing schools and hospitals are starting to conduct reiki classes. The Govt’s alternative medicine center has started studies on Reiki.
Just because they are schools you think it’s okay? And the Gov’t doing this is okay?
My wife is a nurse and a Reiki master herself and there is nothing evil about her. While I don’t fully understand it myself, I don’t think “evil” is in the equation.
Just because your wife is not evil does not mean that Reiki is not evil. What she doesn’t know CAN and will eventually hurt her.
When someone drinks poison and they don’t believe or know they are being poisoned, they will still be harmed by that poison whether they believed or knew it was in the drink or not.
BTW, nobody conjures up any spirits as far as I know.

Reiki - A Catholic Perspective
…I was recently at a function where I met someone who said
that he practices some aspects of Reiki along with regular
massage and I began to realise just how many people - even
Catholics - accept this as perfectly normal. Not one Catholic I
spoke to that day could understand why I perceive such
practices as potentially dangerous or why I was concerned
about what they saw as a natural form of healing that has
nothing to do with spiritual practices.
And little wonder, when
many practitioners either say they haven’t a clue where the
energy they profess to “channel” comes from, or completely
deny that there is any spiritual element involved. Yet the entire
concept is based on New Age thinking, which, according to
the Vatican, is not compatible with Christianity, and the very
name “Reiki” belies any claim that it can be regarded as a
purely natural method of healing.
So the person practicing Reiki might not have any idea that they could possibly be “conjuring up” spirits of which they have no idea and could possibly be “evil” ones.
This too;
Evil Spirits
I don’t believe that most Reiki practitioners set out
to deliberately use evil spirits. Many don’t believe in
the existence of evil spirits, while those who are
practicing Christians believe they have protection from
these spirits, simply by invoking the name of Jesus.
But not believing in something doesn’t make it cease
to exist and being a disciple of Jesus Christ also
means being obedient to our Heavenly Father.
New Age practices and beliefs … including Reiki …
take us into realms forbidden by God.
