But the great-souled ones, O son of Pritha, who rest in the divine nature, worship me with minds turned to nothing else, knowing me as the source of beings and as imperishable.
Explanation
After describing deluded people who take refuge in a demonic, bewildering nature (prakṛti), Krishna now contrasts them with the mahātmās, the great-souled, who rely on a divine nature (daivī prakṛti). They worship him single-mindedly (ananya-manas) because they know him as the imperishable origin of all beings. Commentators differ on whether the "divine nature" means cultivated virtues like those listed in chapter 16 or the Lord's own higher power, but both agree it points to devotion based on knowledge.
