13. These two the mind and respiration, stand in relation of the car and driver to one another, and what living being is there, that is not driven along by them in their train? 14. It was in this manner that the supreme spirit, hath ordained the mind and vital breath, in the very beginning of creation; and therefore this law of their co-operation, continues unaltered to this day. 15. Hence the mind and vital airs are acting in concert in all living bodies, and conducting them at all times in all places in their stated course or action all along (except those of yogis who have repressed them under their subjection). 16. The co-equal course of both, serves to the regular conduct of the functions of life (as in the waking state); but their unequal course, produces dissimilar effects (as that of dreaming when the mind alone is active); and the inactivity of both causes the inertness of the body and soul (as in the state of sound sleep). 17. When the intestines are blocked by the chyle of food taken into them, and the breathing becomes dull and slow; the mind also becomes calm and quiet, and then ensues the blissful state of sound sleep. 18. When the stomach is filled with food, and the lungs are languid with weariness, the breathing then remains without its inflation, and brings on <a> state of sweet and sound sleep of _susupti_ or _hypnotism_. 19. Again when the intestinal parts are cool and phlegmatic, or exhausted by effusion of blood owing to some sore or wound, and the breathing being stopped in the body, there comes the state of numbness of sleep. 20. The ascetic said:--Then I had entered into his heart, it became all dark to me as night; and he fell into a sound sleep, from his satiety with the fulness of his food. 21. I was there assimilated into one with his mind, and lay in deep sleep with himself without any effort of my own. 22. Then as the passage of his lungs was re-opened, after digestion of the food in his stomach; his breathings resumed their natural vibration, and he began to breathe out slowly and softly in his slumbering state. 23. After the sound sleep had become light and airy, I beheld the sunny world arising out of my breast, and appearing manifest before me in my dream. 24. This world seemed to rise out of the troubled ocean, and to be filled with water (seas) upon its surface; it was released from the darkness of diluvian clouds, which had enveloped it, like the mists overhanging on oceans. 25. There was a hurricane blowing over it, bearing aloft the rocks and stones, in its whirling and uproarious course; and carrying away uprooted arbours, with the furze and grassy turfs along with them. 26. It was carrying away and casting all about, the fragments and remains of the last conflagration of desolation; and hurling down the detachments of celestial cities from high.
