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. 46. Again when the body is thus filled with the inflated air, and the wind confined in the Kundaliní artery, is carried upwards by the vital breath (of respiration), from the base or fundamental tube at the bottom, to the cell of the cranium in the head, it touches the consciousness seated in the brain, and drives away the fatigue of the process. (This is called the ascent of the vital air in its heavenward journey). 47. Thence the wind rises upward as smoke into the air, carrying with it the powers of all the arteries attached to it like creepers clinging to a tree; and then stands as erect as a stick, with its head lifted upwards like the hood of a snake. (The art of mounting in the air, is as the act of jumping and leaping into it).
