Sanskrit:

श्वोभाविनि त्वमजितोद्वहने विदर्भान्गुप्त: समेत्य पृतनापतिभि: परीत: ।निर्मथ्य चैद्यमगधेन्द्रबलं प्रसह्यमां राक्षसेन विधिनोद्वह वीर्यशुल्काम् ॥ ४१ ॥

ITRANS:

śvo bhāvini tvam ajitodvahane vidarbhānguptaḥ sametya pṛtanā-patibhiḥ parītaḥnirmathya caidya-magadhendra-balaṁ prasahyamāṁ rākṣasena vidhinodvaha vīrya-śulkām

Translation:

O unconquerable one, tomorrow when my marriage ceremony is about to begin, You should arrive unseen in Vidarbha and surround Yourself with the leaders of Your army. Then crush the forces of Caidya and Magadhendra and marry me in the Rākṣasa style, winning me with Your valor.

Purport:

As Śrīla Prabhupāda points out in Kṛṣṇa, the Supreme Personality of Godhead, Rukmiṇī, being born of royal blood, certainly had a brilliant grasp of political affairs. She advised Śrī Kṛṣṇa to enter the city alone and unnoticed and then surround Himself with His military commanders so He could do what was needed. Śrīla Viśvanātha Cakravartī compares the coming fight to the Lord’s churning of the ocean to extract the goddess Lakṣmī. Gorgeous Rukmiṇī, the goddess of fortune, would be gained in the coming turbulence.
