Bhagavad Gita - Chapter 14 - Guna Traya Vibhaga Yoga - The Yoga of Understanding the Three Modes of Material Nature

Bhagavan Shri Krishna replied: One who does not like or dislike the presence of illumination, attachment or delusion or laments their absence, who remains dispassionate and is not affected by the modes, who remains unwavering, who is equal in both happiness and distress, who remains content in the self, who sees no intrinsic difference between a lump of earth, a stone and gold, who remains undisturbed in both favorable and unfavorable circumstances, who is wise, to whom insult and praise are equal, who considers honor and infamy to be the same, who is impartial towards both friend and enemy, and who renounces all mundane activities – such a person is considered to be beyond the modes of material nature.
