न प्रहृष्येत्प्रियं प्राप्य नोद्विजेत्प्राप्य चाप्रियम्। स्थिरबुद्धिरसम्मूढो ब्रह्मविद्ब्रह्मणि स्थितः

He who knows and lives in the Absolute remains unmoved and unperturbed; he is not elated by pleasure nor depressed by pain.

Resting in Brahman, with a steady intellect and undeluded, the knower of Brahman neither rejoices upon obtaining what is pleasant nor grieves upon obtaining what is unpleasant.
