Bhagavad Gita 2.56 · Duhkheshv Anudvigna Manahदुःखेष्वनुद्विग्नमनाः सुखेषु विगतस्पृहः।वीतरागभयक्रोधः स्थितधीर्मुनिरुच्यते ॥

Lord Krishna gives His answer to the second part of Arjuna's question as to the conduct of a sage of steady wisdom in the 56th, 57th and 58th verses.The mind of a sage of steady wisdom is not distressed in calamities. 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).
