“But, furthermore, thought commences and corresponds with respiration. The reader has before attended to the presence of the heaving over the body; now let him _feel his thoughts_, and he will see that they too heave with the mass. When he entertains a long thought he draws a long breath; when he thinks quickly, his breath vibrates with rapid alternations; when the tempest of anger shakes his mind, his breath is tumultuous; when his soul is deep and tranquil, so is his respiration; when success inflates him, his lungs are as tumid as his conceits. Let him make trial of the contrary: let him endeavor to think in long stretches at the same time that he breathes in fits, and he will find that it is impossible; that in this case the chopping lungs will needs mince his thoughts. Now the mind dwells in the brain, and it is the brain, therefore, which shares the varying fortunes of the breathing. It is strange that this correspondence between the states of the brain or mind, and the lungs, has not been admitted into science; for it holds in every case, at every moment. In truth it is so unfailing, and so near to the center of sense, that this has made it difficult to regard it as an object; for if you only try to think upon the breathing, in consequence of the fixation of thought, you stop the breath that very moment, and only recommence it when the thought can no longer hold, that is to say, when the brain has need to expire. Now Swedenborg, with amazing observation and sagacity, has made a regular study of this ratio between the respiration and the thoughts and emotions; he shows in detail that the two correspond exactly, and moreover that their correspondence is one of the long-sought links between the soul and the body, whereby every thought is represented and carried out momentaneously in the expanse of the human frame. It is difficult to give a more plain or excellent reason of the tie between the body and the soul, than that the latter finds the body absolutely to its mind; while on the other hand, the living body clings to the soul, because it wants a friendly superior life to infuse and direct its life.”
