Other people are mirrors. In them, you see the reflection of your own self. Sometimes the reflections are distorted, but they are still helpful in coming to terms with yourself.
Often it so happens that you express at length your deepest passion, what you value, only to be ridiculed and ignored in the end. It has not come across to the listener. Your eloquent expressions have fallen on deaf ears. At those moments, you feel as if you have been betrayed by the world, and you start secretly licking your wounds. And yet, what is actually happening then is a beautiful self-recognition. You have come to your true self by stumbling on the rocky surface of miscommunication.
At other occasions the resonance is overwhelming, sometimes almost frightening. You feel your own idea appreciated and absorbed by the other party. It starts going to and fro between you and him (her), until the energy is magnified and reach a truly phenomenal dimension. You embrace the bliss of living, and being together becomes magic.
Whether resulting in resonance or rejection, other people are always mirrors, reflecting ourselves in a yet unelucidated mathematics of transpersonal infection.
