दुःखेष्वनुद्विग्नमनाः सुखेषु विगतस्पृहः।
।।2.56।।दुःखोंकी प्राप्ति होनेपर जिसके मनमें उद्वेग नहीं होता और सुखोंकी प्राप्ति होनेपर जिसके मनमें स्पृहा नहीं होती तथा जो राग भय और क्रोधसे सर्वथा रहित हो गया है वह मननशील मनुष्य स्थिरबुद्धि कहा जाता है।
To be free from an agitated mind is not to become aggrieved when situations arise of impending affliction and difficulty or bereavement for something cherished and lost. To not be elated in happiness is to remain in an unattached and passive state even when joyous events occur. Desire is the longing for things not obtained. One must learn to be free from this. Fear is worrying for prospective sorrow which may be caused by bereavement of what is cherished and the projection of the coming of unwanted things. One must learn to be free from this. Anger is that disturbed state of mind and irritated feelings produced of pain from others causing separation from what is cherished or giving the experience of things not cherished. One must learn to be free from this. Such a being is a muni or one of profound contemplation on the soul. This being is known as sthita-prajna situated in perfect knowledge of transcendental consciousness. Lord Krishna describes the next lower stage in the next verse.
