Let's put aside the fact that Dr. Usui was a Christian preacher or that he discovered Reiki specifically while looking for an answer regarding how Christ healed through the laying-on of hands, which is mentioned numerous times in the Bible and exists in nearly all cultures globally, and instead discuss the chakras themselves.
The chakras, also called Ki Centers (this term will be important later), are located at various physical points on the body. There are minor chakras in addition to the main ones shown in the image but I am not going to discuss them here. Any scholar of theology will understand the importance of numerology. There are 7 main chakras, seven being the number for God Himself as it symbolizes completion and perfection.
Our very bodies themselves were created by God so therefore nothing about them can be in contradiction to God. Because the chakras are physical locations on the human body, their very existence is proof of being from God.
In the New Testament, book of Revelation 1:20, we see reference again to the chakras. Where it states, “as for the mystery of the seven stars, which you saw in my right hand, and the seven golden lamp stands. The seven stars are the angels of the seven churches. And the seven lamp stands are the churches.” It is quite clear in this verse that the seven lamp stands and the seven churches are indeed the chakras. The lampstands themselves are symbols of spiritual light shining out to a spiritually dark world. When the Holy Spirit enters us, we now have true light and are no longer filled with darkness. The church leads people to this light, Jesus Christ. Six is the number of man, and with Christ, we are made perfect–7. We know that light contains color as seen in the rainbow, itself caused by reflection, refraction and dispersion of light. The rainbow is God's gift to the world and to humanity following the Great Flood, and the colors of the chakras correlate to the colors of the rainbow. We can see these wind vortexes as beacons of light, vibrating a spectrum of colors that are crucial for proper functioning and health of the whole body, and they are revealing. The body of Christ brings truth, color, and real healing to the world with the guidance and help of the Holy Spirit.
And the seven stars that are mentioned are the preceding deities, referred to as angels in each chakra. Ironically (or not so much at this point), there are six archangels that, together with the King, make up the seven Spirits of God or Sons of God. The colors used to represent each archangel correlate to the colors of the rainbow, which are used to express the various chakras. There are no coincidences...
