Thanks for your comment, Kevin.
Yes, you are right. The quote you highlighted basically says everyone and everything in your reality is sharing a “degree” of common vibration/energy/frequency. But each is also unique.
Vibration/energy/frequency is complicated. I recently wrote a lengthy piece specifically on that topic (linked below). As I see it, frequency is how fast an energy wave is vibrating. That indicates its dimension (faster=higher). The influence/power of the energy relates to its “amplitude” (amps). So if someone vibrates at a fast frequency, but with a low amplitude, they would be in a high state of consciousness, but it would have influence others less. Similarly, a slow frequency/vibration person could have a high amplitude/power impacting many around them.
