…instead of this:
Reiki has foundational beliefs and practices that are irreconcilable with Catholicism,
including not recognizing Jesus as a divine Person and the Savior of all mankind. Reiki
involves a belief similar to pantheism, in which a universal life energy—not Jesus—provides
life to all living beings and is also said to govern the Reiki healing process. Because
Reiki practitioners believe they can harness and use this universal life energy, Reiki is
not simply a form of superstition but rather opens oneself up to dangerous involvement in
the occult practices of divination and magic (cf. Catechism of the Catholic Church,
nos. 2111, 2116-17).
As noted above, in Reiki, spiritual energy is said to be transferred from master to student
during the attunement process. The Catechism makes clear that all “attempts to tame occult
powers, so as to place them at one’s service and have a supernatural power over others—even
if this were for the sake of restoring their health—are gravely contrary to the virtue of
religion” (no. 2117). The Church also warns against the occult practice of “divination,”
which include using mediums to communicate with spirits (no. 2116). The attunement process,
as described by Reiki advocates, involves attempting to use what the Church would describe
as occult powers…
In its 2003 interdicastery report on the New Age, the Vatican distinguishes between
“pantheism,” “the belief that everything is God,” and “panentheism,” i.e., "that everything
is in God and God is in everything."6 Given its personal description of the divine “Rei,”
Reiki is more accurately categorized as panentheism, employing a belief in God that is
clearly not Christian…
Jesus is not "a universal life energy, supernatural knowledge or spiritual consciousness as
described by the Reiki belief system. Jesus is a divine Person who is all-knowing and
all-powerful. In addition, a Catholic may not and should not invoke God other than in the
name of the Father, the Son or the Holy Spirit, i.e., the Holy Trinity. Invoking God or a
“God consciousness” otherwise makes oneself vulnerable to an evil spirit or spirits that
might become present. Furthermore, while the Bible and Christian Tradition affirm praying
with the laying on of hands, the attunement process is something quite different. It is not
Christian in origin and therefore, not surprisingly, does not invoke the Persons of the
Trinity. It presumes to invoke an impersonal “God Consciousness,” which is assisted in
attunement process by unnamed “spiritual beings.”…
“This is dangerous stuff,” said Fr. Hampsch, who said that he was cautious in learning about
Reiki before condemning it. While he describes Reiki as a “very subtle” New Age practice,
Father Hampsch said that there is undoubted danger, as with other occult practices, because
one opens oneself up to the influence of evil spirits. He said that there is always the
“devil’s compensation” in occult practices, including improving one’s health, but that the
“payment” is always worse, including addictions, problems with relationships, and even
suicide.

In a nutshell, the pratice of reiki is condemned in the Catholic Church
