न बन्धो न च मोक्षः स्यात् पुरुषो न भवेद्यदि| कारणं पुरुषस्तस्मात् कारणज्ञैरुदाहृतः ||४१||
Thus, the Purusha is recognized as a cause (of creation) by those well versed in the theory of causation. If Purusha is not recognized as a chief cause, then everything mentioned above will be considered as causeless.
न चेत् कारणमात्मा स्याद्भादयः [२] स्युरहेतुकाः| न चैषु सम्भवेज् ज्ञानं न च तैः स्यात् प्रयोजनम् ||४२||
Then the theory of cause and effect which is a fundamental tenet of Ayurveda will fail and no one will put any effort in understanding the cause of any effect.
यो वदेत् स वदेद्देहं सम्भूय करणैः कृतम्| विना कर्तारमज्ञानाद्युक्त्यागमबहिष्कृतः ||४४||
Without a potter, can a pitcher be constructed with materials like mud, rod, and wheel alone? Can a house be constructed with mud, straw, and beams, if there is no mason? If the answer is “no” in both these cases, how can we expect the body to be created just by virtue of the combination of different sense organs, without a conscious agent? It is only an ignorant person devoid of rational outlook and scriptural knowledge who can assume otherwise.
All the sources of knowledge, including scriptures that serve as an instrument for acquiring knowledge of various kinds, establish the causality of Purusha.
