But the great souls, O Arjuna, partaking of My divine nature, worship Me with a single mind (with the mind devoted to nothing else), knowing Me as the imperishable source of beings.

But the great souls, son of Pritha, who take refuge in the divine nature, worship me with minds turned to nothing else, knowing me as the imperishable source of beings.

In contrast, the great souls, mahātman, take refuge in the divine nature, daivī prakṛti. Knowing Krishna as the imperishable source of beings, they worship him with minds that turn to nothing else. The divine nature here means a disposition of humility, clarity and goodness, opposed to the demonic disposition just described. The verse links character and devotion: those whose nature has become gentle and clear naturally turn towards the source of all. Their single-minded worship flows from understanding.
