9. Vasishtha replied:--It is the opening and closing of the mouth of the aorta in the breast, that lets in and out the vital breath, through the passage of its hole and the lungs. 10. As you see the bellows of ironsmiths about you, having a hollow inside them, so it is the hollow of the aorta, which lets in and out the vital air, by the breathing of the heart. 11. Ráma rejoined:--It is true that the ironsmith closes and expands the valves of the bellows; but tell me sir, what power blows the wind pipe of the heart, and lets the air in and out of the inner lungs. 12. How the single breath of inhalation becomes a centuple (in order to pass into a hundred channels of the arteries), and how these hundreds combine again into one (in their exhalation); and why are some as sensible beings, and others as insensible as woods and stones. 13. Tell me sir, why the immovables have no oscillation at all; and why the moving bodies alone are possessed of their pulsation and mutation (and why <is> the vegetable creation deprived of motion, when it is possessed of sensibility in common with the animal creation). 14. Vasishtha replied:--There is an internal percipience (inner man), which moves the interior cords of the body; just as the ironsmith plies his bellows in the sight of men. 15. Ráma rejoined:--Say sir, how is it possible for the subtile and intactile soul, to move the vital airs and tangible entrails in the animal body. 16. If it be possible for the imperceptible perceptive soul, to put in motion the intestinal and tactual entrails of the body; then it may be equally possible for the thirsty soul, to draw the distant water to it. (In order to quench its thirst, instead of going to the watery pool). 17. If it be possible for the tangible and intangible, to come together in mutual contact at their will; then what is the use of the active and passive organs of action (if the will alone be effective of any purpose). 18. As the intangible powers of the soul or spirit, bear no connection whatever with the outward objects of the world; some think they can have no effect on the internal organs of the body (in putting them to action). So please explain it more fully to me. 19. Tell me, how you yogis perceive the outward corporeal things in your inner incorporeal souls; and how your formless souls, can have any command over or any contact with solid bodies. 20. Vasishtha replied:--Hear me tell you for rooting out all your doubts, and these words will not only be pleasing to your ears, but give you a conception of the unity of all things. 21. There is nothing here, at any time, what you call as a solid substance or tangible body, but all is a wide and extended vacuum of the rare and subtile spirit. 22. This spirit is of the nature of the pure Intelligence, quite calm and intangible; and all material things as the earth, are as visionary as our dreams, and the creatures of imagination.
