Bhagavad Gita Verse 6.32

अर्जुन ! जो योगी अपनी भाँति सम्पूर्ण भूतोंमें सम देखता है और सुख अथवा दुःखको भी सबमें सम देखता है, वह योगी परम श्रेष्ठ माना गया है|

Dear Arjuna, the Yogi who looks upon all beings as his own self, treats all beings equally, and considers happiness and misery as the same, is truly a great being himself.
