Vibrations

Vibrations can be powerful, and like other things that are powerful, vibrations can have two sides. Vibrations can be "good", beautiful as with music and healing as with sound vibrations that correspond with chakra centers in the body.  The collapse of the Nimitz Freeway is an example of how a vibration can be "bad". The low-frequency vibration of the earthquake resonated with the structural layers of the freeway, and since mud layers responded strongly to the earthquake, it caused the bridge to collapse. Another example of a "bad" vibration is with the Honda lawsuit of how the rattling of the car made occupants feel nauseous. The extent to which a vibration is "good" or "bad" depends on the frequency, the situation, and the material matter or people being influenced.

In my yoga practice I experience "forced resonance" while doing pranayama breathing technique called bhramari. Sounds are made with the mouth for the duration of exhalation, similar to the sound of a humming bee. When practicing bhramari, the sounds can be made at various pitches to target the seven different chakra centers  in the body. One can focus on vibrations at particular tones and frequencies to target a healing effect on body tissues, physical and emotional issues associated with each chakra.

The English translation of the Chinese word "qi" as "energy" is not accurate. Qi encompasses more than energy because it involves an interaction between vibration, air, and vital substances. Qi is not constant but rather has varying contextual characteristics - of being free flowing or blocked, organized or unorganized, righteous or harmful, constructive or destructive, etc. There can be comparisons drawn between the Western understanding of "energy" with Chinese word "qi", but the two words are not equivalent.
