आत्मौपम्येन सर्वत्र समं पश्यति योऽर्जुन ।सुखं वा यदि वा दुःखं स योगी परमो मतः ॥
ātmaupamyena sarvatra samaṃ paśyati yo’rjunasukhaṃ vā yadi vā duḥkhaṃ sa yogī paramo mataḥ
He, O Arjuna, who sees with equality everything in the image of the self whether it be grief or it be happiness, him I hold to be the supreme Yogin.
Gītā 6·32That is the old Vedantic knowledge of the Upanishads which the Gita holds up constantly before us; but it is its superiority to other later formulations of it that it turns persistently this knowledge into a great practical philosophy of divine living. Always it insists on the relation between this knowledge of oneness and Karmayoga, and therefore on the knowledge of oneness as the basis of a liberated action in the world. Whenever it speaks of knowledge, it turns at once to speak of equality which is its result; whenever it speaks of equality, it turns to speak too of the knowledge which is its basis.
