न किञ्चनोचतु: प्रेम्णा साश्रुकण्ठौ कुरूद्वह ॥ ३४ ॥
pitarāv abhivādya ca
na kiñcanocatuḥ premṇā
O hero of the Kurus, Kṛṣṇa and Balarāma embraced Their foster parents and bowed down to them, but Their throats were so choked up with tears of love that the two Lords could say nothing.
After a long separation, a respectful child should first offer obeisances to his parents. Nanda and Yaśodā gave their sons no opportunity for this, however, for as soon as they saw Them they embraced Them. Only then could Kṛṣṇa and Balarāma offer Their proper respects.
