Breath is a light in itself, and it becomes projected like the beam from a searchlight thrown upon an object. When the breath is coarse, undeveloped, it is full of material atoms which dim its light, but a developed breath is sometimes not different from the light of the sun but even brighter than that. Breath being a light from another dimension, which is unknown to science today, it cannot be visible to the ordinary physical eyes. The glands of the physical eyes must be cleansed and purified first by Pasi Anfas before the eyes can see the light of breath.

What people call the aura is the light of breath, but it is not everyone one sees it. A radiant countenance is a proof of an aura which lightens it, and the lack of it is the lack of light in the breath. A seer sees the sign of a death more clearly and longer beforehand than a physician can. The reason is that the seer sees in the aura of a person whereas the physician sees only the condition of the body.

There is a belief in India that there are some cobras that have light in their head, the light by which they find their way through the dark. They make a hole in the earth miles long, and illuminate the hole by their own light which is centered in their head. As two wires, positive and negative, cause the electric light to manifest, so the two currents of breath, Jelal and Jemal, when connected in the head in the way they ought to be, cause the light to manifest.

Many experience the phenomena of the light of breath, and yet doubt if it can be true, for they think it is perhaps an imagination. Others, who are incapable of seeing that light, confirm their doubt. The Sufi, by the development of breath, experiences this light, which becomes for him a proof of the existence of that dimension which is unknown to the ordinary world.
