यथास्थूलमनिर्वाह्य दोषाञ्छारीरमानसान्| रसायनगुणैर्जन्तुर्युज्यते न कदाचन ||३६||
[Importance of purification before rasayana] An individual can never get the benefits of Rasayana if he has not undergone grossly the process of samsodhana of his physical as well as mental impurities.
तदेतन्न भवेद्वाच्यं सर्वमेव हतात्मसु| अरुजेभ्योऽद्विजातिभ्यः शुश्रूषा येषु नास्ति च ||३८||
Such a treatment should not be prescribed to those who have degenerate self, are disease free, are not twice born and who are reluctant to receive such a treatment.
ये रसायनसंयोगा वृष्ययोगाश्च ये मताः| यच्चौषधं विकाराणां सर्वं तद्वैद्यसंश्रयम् ||३९||
[Historical examples] The Rasayana preparations, vajikarana recipes and remedies designed for the treatment of diseases – all depend on (vision and skill of) the physician.
Hence the wise should honour with all means the treating physician who promotes life, is wise and well versed in the science of life as the king of gods honours Ashwins.
