dhairyeṇa rājan bahu-manyamānaḥ
kṛtāñjaliḥ prāha yadu-pravīraṁ
śīrṣṇā spṛśaṁs tac-caraṇāravindam
According to Śrīla Jīva Gosvāmī, the fear of separation from Lord Kṛṣṇa was continually entering the mind of Śrī Uddhava, and thus he tried to maintain his enthusiasm by remembering the Lord’s great kindness upon him. He steadied his mind with feelings of gratitude toward the Lord.
