Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 52

Sanskrit:

अहत्वा दुर्मतिं कृष्णमप्रत्यूह्य यवीयसीम् ।कुण्डिनं न प्रवेक्ष्यामीत्युक्त्वा तत्रावसद् रुषा ॥ ५२ ॥

ITRANS:

ahatvā durmatiṁ kṛṣṇamapratyūhya yavīyasīmkuṇḍinaṁ na pravekṣyāmītyuktvā tatrāvasad ruṣā

Translation:

Because he had promised “I will not reenter Kuṇḍina until I have killed wicked Kṛṣṇa and brought back my younger sister,” in a mood of angry frustration Rukmī took up residence at that very place.

Purport:

Śrīla Viśvanātha Cakravartī explains that the word bhoja means “experience” and that, kaṭaḥ, according to the Nānārtha-varga dictionary, means “vow.” Thus Bhojakaṭa is the place where Rukmī experienced misery as a result of his vow.
