Hazrat Inayat Khan

The reach of vibrations is according to the fineness of the plane of their starting point.  To speak more plainly, the word uttered by the lips can only reach the ears of the hearer, but the thought proceeded from the mind reaches far, shooting from mind to mind. 

The vibrations of mind are much stronger than those of words.  The earnest feelings of one heart can pierce the heart of another; they speak in the silence, spreading out into the sphere, so that the very atmosphere of a person's presence proclaims his thoughts and emotions.  The vibrations of the soul are the most powerful and far reaching; they run like an electric current from soul to soul.

Although a friend or a beloved may be thousands of miles away he will feel our attachment, our affection.  The feeling originates here, but manifests over there; this shows that in our feelings we are larger still.
