He is not affected by the three afflictions (Taapas) -- Adhyatmika (arising from diseases or disorders in ones own body), Adhidaivika (arising from thunder, lightning, storm, flood, etc.), and Adhibhautika (arising from scorpions, cobras, tigers, etc.). When he is placed in an affluent condition he does not long for sensual pleasures. (Cf.IV.10).
