The Portacle


It has long been known that the mind will reject entrainment once it has habituated to a nonchanging signal. Therefore, it is important for the entrainment signal to “lead” the mind by continuously changing throughout the program. This requires some way to monitor the user in some way so that their brainwaves can be known and coaxed into following an ever-changing signal. Thus, the next generation of LSV devices will include improved biometric monitoring of some type.

Biofeedback usually involves a signal (unrelated to the user) to warn or advise the attainment of some marker such as an “alpha” state. However, the optimal use of such information would be to drive a person at their own resonant frequencies, thus enhancing the harmony that they already possess. This alone could usher in the new healing paradigm spoken of previously.


Simple singular frequencies form into sine waves. All other wave shapes include overtones and form complex waveform with multiple frequencies (see diagram one). Light and sound devices, as well as other types of frequency generators, use a wide variety of waveforms.

Whereas sine waves produce pure fundamentals, square waves include the series of odd overtones, and triangular waves are composed of a series of even overtones. Each type of waveform has its advantages and limitations, but the most effective waveform would be the unique personal waveform of the user.

With most systems, biometric measurement is made with one device or technique and then chosen frequencies are dialed into a separate generator for feedback to the user with sine, square or triangular waveforms. Supercomputers can take the input, analyze the sample, remove the noise and dissonance, and feed back the harmonic content using the person’s own private waveform.

The modern industry of health biometrics really got its start with EEG measurements of brainwaves.

Other metabolic indicators followed including galvanic skin response, skin temp and sweat, EKG analysis of heartbeats and others. Recently, heart-rate variability (HRV), which provides a more accurate and simultaneous view of both the sympathetic and parasympathetic nervous systems, has become popular. However, whereas the brain shows how one is thinking and the heart how one is feeling, the voice combines both into a singular expression of one’s manner of being and doing. It makes sense that the voice would best describe who a person is and what they want, since it is the mechanism given to them by the universe to say who they are and what they want.

However, it is the breath that actually produces the majority of frequencies that make up one’s voice. Breath is known in many cultures as the primal wave. It is the first and last cycles of life…the alpha and omega…the origin and destiny of the wave. The way one inhales and exhales reveals how they take in life and then put it back out again. Brainwaves, heartbeats, cerebral pulse and other cycles come afterward and represent the history of the bio-chronological wave. Biometric monitoring will become the focus of more research and lead to the one that gives the most complete view of a person’s state.
