Sanskrit:

उपलब्धं पतिप्रेम पातिव्रत्यं च तेऽनघे ।यद्वाक्यैश्चाल्यमानाया न धीर्मय्यपकर्षिता ॥ ५१ ॥

ITRANS:

upalabdhaṁ pati-premapāti-vratyaṁ ca te ’nagheyad vākyaiś cālyamānāyāna dhīr mayy apakarṣitā

Translation:

O sinless one, I have now seen firsthand the pure love and chaste attachment you have for your husband. Even though shaken by My words, your mind could not be pulled away from Me.

Purport:

Śrīla Viśvanātha Cakravartī quotes the following verse describing the pure love between Rukmiṇī and Kṛṣṇa: “When the affectionate bond between a young man and a young woman can never be destroyed, even when there is every cause for the destruction of that relationship, the attachment between them is said to be pure love.” This is the nature of the eternal loving affairs between Lord Kṛṣṇa and His pure conjugal associates.
