आत्मौपम्येन सर्वत्र समं पश्यति योऽर्जुन ।
सुखं वा यदि वा दुःखं स योगी परमो मतः ॥
ātmaupamyena sarvatra samaṁ paśyati yo’rjuna |
sukhaṁ vā yadi vā duḥkhaṁ sa yogī paramo mataḥ ||
(Śrīmad Bhagavad-gītā: 6.32)
“One who sees everything equally in likeness to oneself, be it happiness or suffering, is considered a great yogī [i.e., a great yogī is one who sees the happiness and suffering of oneself and others as the same thing, desires happiness for all and suffering for no one, and is thus compassionate to all].”
