36. The vital breaths carry the essence of the food we take to the inferior organs, as the currents of a river carry the floating woods down the stream.
37. The crude matter which remains in the intestines, for want of its assimilation into blood, and circulation in the frame by restraint of breathing; turn at the end to be sources of multifarious maladies in the constitution.
38. Thus it is that the perturbed states of the mind and spirit, produce the diseases of the body, and are avoided and removed by want of mental anxiety. Now hear me tell you, how the mantra-exorcism serve to drive away the diseases of the body.
39. As the karitakí fruit (chebule myrobalan) is purgative of its own nature, and purges out the crudities from the bodies; so the headwork into the mysterious meaning of the mantras, removes the crude diseases from the frame. (Such are the mystic letters ya, ra, la, va, in the liquids y, r, l, v), signifying the four elements of earth, water, air and fire; curative of many diseases by reflection on their hidden meaning.
40. I have told you Ráma, that pious acts, holy service, virtuous deeds and religious observances, serve also to drive the diseases from the body; by their purifying the mind from its impurities, as the gold is depurated by the touch stone.
41. The purity of the mind produces a delight in the body; as the rising of the full moon, spreads the gentle moonbeams on earth. (Every good act is attended with a rapture, recompenses the deed; or as the maxim goes "virtue has its own reward").
42. The vital airs breathe freely from the purity of the mind, and these tending to help the culinary process in the stomach, produce the nutrition of the body, and destroy the germ of its diseases. (The germs of growth and decay and of life and death, are both connate in the nature of all living beings; and the increase of the one, is the cause of the decrease of the other).
43. I have thus far related to you, Ráma! concerning the causes of the rise and fall of the diseases and distempers of the living body, in connection with the subject of the main artery of Kundaliní; now hear me relate to you regarding the main point of one's attainment of consummation or siddhi by mean of his yoga practice.
44. Now know the life of the puryashtaka or octuple human body, to be confined in the Kundaliní artery, as the fragrance of the flower is contained in its inner filament.
45. It is when one fills the channel of this great artery with his inhaling breath, and shuts it at its mouth (called the Kurma opening), and becomes as sedate as a stone; he is then said to have attained his rock like fixity and firmness, and his siddhi or consummation of garima or inflation.
