धर्म्याः क्रिया हर्षनिमित्तमुक्तास्ततोऽन्यथा शोकवशं नयन्ति| शरीरसत्त्वप्रभवास्तु रोगास्तयोरवृत्त्या न भवन्ति भूयः ||४१||
Virtuous acts bring forth happiness while the contrary ones cause sorrow. The source of all diseases is the body and the mind. When these (body and mind) are absent, the diseases can not recur.( This state is known as Moksha )
रूपस्य सत्त्वस्य च सन्ततिर्या नोक्तस्तदादिर्नहि सोऽस्ति कश्चित्| तयोरवृत्तिः क्रियते पराभ्यां धृतिस्मृतिभ्यां परया धिया च ||४२||
The beginning point of the consistent exixtence of physique and psyche is not mentioned anywhere and for sure there is no such beginning. Their absence can be brought out only by excellent restraint, memory and knowledge.
सत्याश्रये वा द्विविधे यथोक्ते पूर्वं गदेभ्यः प्रतिकर्म नित्यम्| जितेन्द्रियं नानुपतन्ति रोगास्तत्कालयुक्तं यदि नास्ति दैवम् ||४३||
Even though the above mentioned two-fold seats of diseases (body and mind) exist, one who always takes precautions against diseases and have control over the senses does not fall prey to diseases except when predestined.
दैवं पुरा यत् कृतमुच्यते तत् तत् पौरुषं यत्त्विह कर्म दृष्टम्| प्रवृत्तिहेतुर्विषमः स दृष्टो निवृत्तिहेतुर्हि समः स एव ||४४||
The deeds of the previous life are known as daiva (fate) and those of the present life as paurusha (personal effort). Imbalance of these (daiva and paurusha) leads to diseases and balance prevents the diseases
One who eliminates the accumulation of doshas of early winter in spring, that of summer in early rains and that of rainy season in autumn, never suffers from seasonal disorders.
