27. The non-essential or extrinsical diseases that are derived from without, are capable of being removed by the application of drugs, the spell of mantras and propitiating as well as obviating charms; as also by medicaments and treatments, according to the prescriptions of medical science and the practice of medical men. 28. You will know Ráma, the efficacy of baths and bathing in holy rivers, and are acquainted with the expiatory mantras and prescriptions of experienced practitioners; and as you have learnt the medical Sástras, I have nothing further to direct you in this matter. 29. Ráma rejoined:--But tell me sir, how the intrinsic causes produce the external diseases; and how are they removed by other remedies than those of medicinal drugs, as the muttering of mantra incantations and observance of pious acts and ceremonies. 30. Vasishtha replied:--The mind being disturbed by anxieties the body is disordered also in its functions, as the man that is overtaken by anger, loses the sight of whatever is present before his eyes. 31. He loses sight of the broad way before him, and takes a devious course of his own; and like a stag pierced with arrows, flies from the beaten path and enters himself amidst the thickest. 32. The spirit being troubled, the vital spirits are disturbed and breathe out by fits and snatches; as the waters of a river being disturbed by a body of elephants, rise above its channel and over flow the banks. (Violent passions raging in the breast burst out of and break down their bounds). 33. The vital airs breathing irregularly, derange the lungs and nerves and all the veins and arteries of the body; as the misrule in the government, puts the laws of the realm into disorder. 34. The breathings being irregular, unsettles the whole body; by making the blood vessels quite empty and dry in some parts, and full and stout in others, resembling the empty and full flowing channels of rivers. 35. The want of free breathing is attended both with indigestion and bad digestion of the food, and also evaporation of the chyle and blood that it produces; and these defects in digestion, bring forth a great many maladies in the system. 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.
