व्यवसायात्मिका बुद्धिर् एकेह कुरुनन्दन ।बहुशाखा ह्यनन्ताश्च बुद्धयोऽव्यवसायिनाम् ॥
vyavasāyātmikā buddhir ekeha kurunandanabahuśākhā hyanantāśca buddhayo’vyavasāyinām
The fixed and resolute intelligence is one and homogeneous, O joy of the Kurus; many-branching and multi-farious is the intelligence of the irresolute.
Gītā 2·41Buddhi, the word used, means, properly speaking, the mental power of understanding but it is evidently used by the Gita in a large philosophic sense for the whole action of the discriminating and deciding mind which determines both the direction and use of our thoughts and the direction and use of our acts; thought, intelligence, judgment, perceptive choice and aim are all included in its functioning: for the characteristic of the unified intelligence is not only concentration of the mind that knows, but especially concentration of the mind that decides and persists in the decision, vyavasāya, while the sign of the dissipated intelligence is not so much even discursiveness of the ideas and perceptions as discursiveness of the aims and desires, therefore of the will. Will, then, and knowledge are the two functions of the Buddhi.
