For each sense, attraction and aversion toward its object are firmly set in place. One should not come under the power of these two, for they are the enemies that block one's path.
Explanation
Krishna is advising Arjuna, after saying that all beings follow their own nature (prakṛti). He explains that each sense naturally carries attraction (rāga) and aversion (dveṣa) toward its objects, and that these two, not the senses themselves, are what block a person's progress. The verse is usually read as teaching that one can still act without being ruled by these pulls; traditions differ on whether this means mastering them through discipline or seeing through them with knowledge.
