अध्याय १७८ — प्राणवायुगतिः तथा शारीराग्निव्यवस्था
Adhyāya 178 — The courses of prāṇa-vāyu and the regulation of the bodily fire
आत्मना सप्तमं काम हत्वा शत्रुमिवोत्तमम् | प्राप्पावध्यं ब्रह्मपुरं राजेव स्थामहं सुखी
ātmanā saptamaṁ kāmaṁ hatvā śatrum ivottamam | prāpya avyayaṁ brahmapuraṁ rājā iva sthāsyāmi sukhi ||
ビーシュマは言った。「自らの内なる修行によって、私は第七のもの—欲（kāma）という至上の敵—を、恐るべき敵を討ち倒すように滅した。私は不滅のブラフマンの都に到るであろう。そこに安住し、王のごとく幸福にとどまる。」

Educational Q&A
Desire (kāma) is portrayed as the most powerful inner enemy; conquering it through one’s own disciplined effort leads to stable happiness and the imperishable state symbolized as brahmapura (abode of Brahman), i.e., liberation.
In Bhīṣma’s instruction in the Śānti Parva, he frames spiritual practice as a battle: by ‘slaying’ desire like a supreme enemy, he declares his resolve to attain brahmapura and abide there content, likened to a king secure in his realm.
