According to Wikipedia resonance :

In physics, resonance is the tendency of a system to oscillate with greater amplitude at some frequencies than at others. Frequencies at which the response amplitude is a relative maximum are known as the system’s resonant frequencies, or resonance frequencies. At these frequencies, even small periodic driving forces can produce large amplitude oscillations, because the system stores vibrational energy.

So let’s think about what that means in human systems. Today… do a little experiment. See if you can resonate with some one else, tune into their frequency and feel their vibrational energy. Tomorrow see if you can get them to resonate with you. And as Jayne Warrilow says “remain open to the energetic field”. Feel the vibe.
