Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 24
अपि मय्यनवद्यात्मा दृष्ट्वा किञ्चिज्जुगुप्सितम् । मत्पाणिग्रहणे नूनं नायाति हि कृतोद्यम: ॥ २४ ॥
api mayy anavadyātmādṛṣṭvā kiñcij jugupsitammat-pāṇi-grahaṇe nūnaṁnāyāti hi kṛtodyamaḥ
Perhaps the faultless Lord, even while preparing to come here, saw something contemptible in me and therefore has not come to take my hand.
Princess Rukmiṇī boldly invited Śrī Kṛṣṇa to kidnap her. When Rukmiṇī did not see Him come, she naturally feared that He had rejected her proposal, perhaps finding some unacceptable quality in her. As expressed here, the Lord Himself is anavadya, faultless, and if He saw some fault in Rukmiṇī she would be an unworthy bride for Him. It was natural for the young princess to feel such anxiety. Furthermore, if Śrī Kṛṣṇa had actually made this decision, it would be natural for the brāhmaṇa to fear Rukmiṇī’s reaction were he to bring her the news, and that would explain why he had not come.
