68. As the high winds rage in the sky and break down the weaker leaves of the branches of trees, so do the vital airs coil in the body and crush the soft food, that has been taken in the stomach. 69. As the winds of the air batter the lotus leaves, and at last dissolve them into the native element; so the internal winds break down the food like the leaves of trees, and convert the food ingested in the stomach into chyle, blood, flesh, skin, fat, marrow and bones one after another. 70. The internal airs clash against one another the produce of the gastric fire, as the bamboos in the wood produce the living fire by their friction. 71. The body which is naturally cold and cold-blooded, becomes heated in all its parts by this internal heat, as every part of the world becomes warmed by the warmth of the sun. 72. This internal fire which pervades throughout the frame and flutters like golden bees over the loti-form heart, is meditated upon as twinkling stars in the minds of the ascetic yogis. 73. Reflections of these lights are attended with the full blaze of intellectual light, whereby the meditative yogi sees in his heart objects, which are situated at the distance of millions of miles from him. (This is called the consummation of clairvoyance or divyadrishti). 74. This culinary fire being continually fed by the fuel of food, continues to burn in the lake of the lotus-like muscle of the heart, as the submarine fire burns latent in the waters of the seas. 75. But the clear and cold light which is the soul of the body, bears the name of the serene moon; and because it is the product of the other fire of the body, thence called the _sumágni_ or the residence of the moon and fire (its two presiding divinities). 76. All hotter lights in the world are known by the names of suns (as the planetary and cometary bodies); and all colder lights are designated as moons (as the stars and satellites) and as these two lights cherish the world, it is named as the _suryágni_ and _somágni_ also. 77. Know after all the world to be a manifestation of the combination of intelligence and ignorance (_i.e._ of the intellect and soul matter), as also of an admixture of reality and unreality among who has made it as such in himself manifest in this form. 78. The learned call the light of intelligence, by the terms knowledge, sun and fire, and designate the unrealities of ignorance, by the names of dullness and darkness, ignorance and the coldness of the moon. (_i.e._ There are antithetical words expressive of Intelligence and ignorance; the former designated as the light of knowledge and reason, the daylight and the light of lamp &c., and the latter as the darkness of night, and the coldness of frost &c.). 79. Ráma said:--I well understand that the product of the air of breath &c. (by their friction as said before); and that the air proceeds from the moon, but tell me sir, whence comes the moon into existence?
