Bhagavad Gita 14.24

14.24 Who is the same in pleasure and pain, who dwells in the Self, to whom a clod of earth, stone and gold are alike, who is the same to the dear and the unfriendly, who is firm, and to whom censure and praise are as one.

The wise person who is equipoised in both happiness and distress, who is tolerant, free from envy, and who is steady in both success and failure, is certainly eligible for liberation.
