। ॥ १७० ॥
In plain words
So much for the Upaniṣads; and there is devotion beside them — two ways, and the Lord taught both. Liberation comes by either one, the one with the struggle or the one without.
Close to the Sanskrit
Thus the Upaniṣad — or, of those two, the two, [namely the Upaniṣadic way and] the devotional, both taught by the Lord; from hardship or from no hardship, liberation would come, among these two.
