buddheḥ

इन्द्रियाणि पराण्याहुरिन्द्रियेभ्यः परं मनः

buddhiḥ — intellect

The senses are said to be greater than the body; greater than the senses is the mind; greater than the mind, the understanding; and greater than the understanding is that.

एवं बुद्धेः परं बुद्ध्वा संस्तभ्यात्मानमात्मना

buddheḥ — than the intellect

Knowing that which is beyond the understanding, steadying the lower self by the higher, strike down this enemy, mighty-armed one — desire, so hard to master.

बुद्धेर्भेदं धृतेश्चैव गुणतस्त्रिविधं श्रृणु

buddheḥ — of intellect

Hear now the threefold division of understanding and of steadiness, according to the strands, described one by one.
