This is an instance of success in separation. A similar satisfaction was observed when Kṛṣṇa returned from the Battlefield of Kurukṣetra to His home at Dvārakā. All of His sons were so overjoyed that out of ecstasy they repeatedly made many mistakes. These mistakes were a sign of complete satisfaction.
Every day Pradyumna looked over Kṛṣṇa's lotus feet with tears in his eyes. These signs of reverential devotion on the part of Pradyumna may be described in the same way they have been described in the cases of other devotees.
