As Seen from the Eyes of Devotional Vedanta. By Bruce Martin. Reiki is a conscious healing energy, emanating from the One conscious Source, which pervades and transcends all of manifestation. Reiki is a specific potency of that unlimited Source, endowed with the frequency to bring healing on all dimensions of embodied being, from the physical, to the energetic, the emotional, the mental, extending in its highest aspect even to the spiritual.
