Here, O joy of the Kurus, there is but a single one-pointed determination; many-branched and endless are the thoughts of the irresolute.

Here, joy of the Kurus, the understanding that is resolute is single, while the thoughts of the irresolute are many-branched and endless.

Krishna contrasts two kinds of mind. The understanding (buddhi) that is resolute, firmly decided, is single and focused. The thoughts of those who lack resolve branch out endlessly, pulled in many directions. In context, this prepares a criticism of people who chase many separate goals through ritual. More broadly, the verse describes a psychological truth: a mind scattered among countless desires cannot act clearly, while a mind gathered around one purpose has strength and direction.
