Shloka 15
व्याधि-गुण-साम्योपदेशः | Discourse on Affliction, Guṇa-Equilibrium, and the Inner Battle
तस्मिन्ननिर्जिते युद्धे कामवस्थां गमिष्यसि । एतज्ज्ञात्वा तु कौन्तेय कृतकृत्यो भविष्यसि
tasminn anirjite yuddhe kāmāvasthāṁ gamiṣyasi | etaj jñātvā tu kaunteya kṛtakṛtyo bhaviṣyasi ||
若在那尚未被征服的战斗中，你不能制胜于己，便将堕入为欲望所驱使的境地。然则，噢，昆蒂之子啊，一旦你将此理洞然明白，你便成为“所当作者已作”的人——使命既毕，目的已成。

Educational Q&A
The verse teaches that the hardest and most decisive battle is the inner struggle for self-mastery; if one does not conquer the mind and senses, one becomes ruled by kāma (desire). Clear understanding of this truth is presented as a decisive step toward becoming kṛtakṛtya—fulfilled in duty and purpose.
Vāyudeva addresses Kaunteya (Arjuna) with admonition and guidance, framing the situation as an ‘unconquered battle’—a moral-psychological struggle. He warns of the consequence of failing to win it (falling under desire’s control) and encourages Arjuna that grasping this principle itself leads toward completion of his rightful task.
