। ॥ १४८ ॥
In plain words
"And no one reaches perfection by renunciation alone." With that line he said this as well: give up the very thing you are meant to do, and no perfection follows.
Close to the Sanskrit
"And not by renunciation alone does one attain perfection" — thus, from the complete abandonment of what ought to be performed, he also declared the absence of attainment.
