Cause of Kalmāṣapāda’s Niyoga under a Curse
तस्यां संजनयामास कुरुं संवरणो नृपः । तपत्यां तपतां श्रेष्ठ तापत्यस्त्वं ततोडर्जुन
tasyāṁ sañjanayāmāsa kuruṁ saṁvaraṇo nṛpaḥ | tapatyāṁ tapatāṁ śreṣṭha tāpatyās tvaṁ tato ’rjuna ||
王サンヴァラナ（Saṃvaraṇa）はタパティー（Tapatī）によりクル（Kuru）をもうけた。ゆえに、アルジュナ（Arjuna）よ—苦行者のうち最も勝れた者よ—汝はその同じ血統に生まれたがため、『ターパティヤ』（Tāpatya）と呼ばれるのである。

Educational Q&A
The verse grounds social and royal identity in lineage: Arjuna and the Kurus are called Tāpatyas because their dynastic ancestor Kuru was born from King Saṁvaraṇa and Tapatī. It emphasizes legitimacy and inherited identity through recognized genealogical descent.
A Gandharva explains to Arjuna the origin of the Kuru line: Saṁvaraṇa fathered Kuru on Tapatī, and thus those born in that line—including Arjuna—are designated Tāpatya, ‘descendants of Tapatī.’
