Mind is creative and thought is living, but out of what does mind create a thought? Out of the atoms of the mental sphere. But the current which attracts the desired atoms to complete a thought is the breath, not that breath which is outwardly manifest, but that part of breath the action of which is not felt by every man. The more length and breadth the breath has the more scope it gives for the creation of thought. It is therefore that the thoughts of the sages and mystics, who have gained mastery over breath, are more substantial and complete in themselves, and besides they prove to be more expressive and impressive.
