[Excerpt from Michael Speaks: July 2011]
[Brian_W] Hi Michael. The term “subtle energy” has been used quite frequently lately and many of us are curious, from a physical standpoint, what frequency and energy range does it fall under on the electromagnetic spectrum for us to detect and harness it? Does it propagate on, parallel to, or perpendicular to the existing electromagnetic spectrum?
We may fall short again in terminology through this channel, but we can say that subtle energies fall just beyond the range of what you would call Electric and Magnetic Fields and frequencies. At this point, we know of no reliable means for detecting these without a living system involved, such as the musculature responses of a human body, which convert these into something observable, and without considering the concept of a empty space, or a vacuum in the calculations.
We do think it is valid to consider subtle energies as being a kind of “vertical” energy vs the “horizontal” energy of observable energy.
All subtle energy would require conversion, if harnessing or directing it were to be an aim.
We are doing our best to convey the details through this channel, and we would suggest continuing to ask these questions in different ways at different times to help in generating a clearer picture.
