Resolute understanding (buddhi) is single here, O joy of the Kurus (Kurunandana). Many-branched and indeed endless, Are the understandings (buddhayaḥ) of the irresolute.
This understanding is unique in its inner core of resolve; diffuse and pointless are the ways irresolute men understand.
(41) The essence of the soul is will and it is really single, but many-branched and infinite are the souls of men devoid of will. Vedic Religion
2.41 O scion of the Kuru dynasty, in this there is a single, one-pointed conviction. The thoughts of the irresolute ones have many branches indeed, and are innumerable.
2.41 In this (Karma Yoga), O Arjuna, the resolute mind is one-pointed; the minds of the irresolute are many-branched and endless.
2.41 Here, O joy of the Kurus, there is but a single one-pointed determination; many-branched and endless are the thoughts of the irresolute.
