O joy of the Kurus, the thinking of the inherently resolute is singular in this.
And the thinking of the irresolute is infinitely many-branched.

Source: Milind S. Pandit

Those who are resolute have only one thought (of Self-realization), but the thoughts of the irresolute are endless and many-branched, O Arjuna.

Source: The Bhagavad-Gita: The Sacred Song

Those who are on this path are resolute in purpose, and their aim is one. O beloved child of the Kurus, the intelligence of those who are irresolute is many-branched.
