There one regains the intellectual connection from the previous life, and strives again toward perfection, oh delight of the Kurus!

Paurva-dehika — “from the previous body” — the yoga-bhraṣṭa recovers buddhi-saṃyoga (connection/intellectual knowledge) from past lives. It is like restarting a game with saved progress.

Tato bhūyaḥ — “from there, again.” The impulse toward saṃsiddhi (perfection, success) continues. Previous effort was not in vain.
