It is the vibrations caused by the breath which become thought-waves which carry the thought from one mind to the other. It is therefore that thought-reading depends so much upon the position in which two people sit with regard to each other, for a certain position makes it easier for the breath to reach than another, although it is not always necessary that a person must be facing one in order to receive thought-waves through breath. If the thought power is strong and the breath is sound enough to carry the thought-waves, a person, whether facing or having his back turned, must receive thought.

The mystics do not only project their own breath and see the condition of their being manifest before themselves, but they can also make themselves responsive to receive the thought-waves of another carried by his breath. This receptivity does not only enable an adept to read other's thoughts, but also to a mystic the condition of another becomes revealed by the projection of another person's breath upon his heart.

Plainly speaking, souls are likened to mirrors, and two mirrors facing one another become projected on one another, one manifesting the reflection of the other. The mirror which has not already a reflection is capable of manifesting the reflection of the other mirror. In this way breath enables a Sufi not only to know and see his own condition of life but also to know and understand the condition of those he comes in contact with.
