veṣaṁ kṛtrimam āsthitam
yathā naṭaṁ raṅga-gataṁ
vijahāsa bhṛśaṁ harīḥ
Śrīla Prabhupāda describes this scene as follows: “On the whole, however, [Pauṇḍraka’s] dress and makeup were clearly imitation. Anyone could understand that he was just like someone on stage playing the part of Vāsudeva in false dress. When Lord Śrī Kṛṣṇa saw Pauṇḍraka imitating His posture and dress, He could not check His laughter, and thus He laughed with great satisfaction.”
Śrīla Jīva Gosvāmī points out that it was a benediction from Lord Śiva that enabled Pauṇḍraka to imitate the Lord’s dress and appearance exactly — a fact gleaned from the Uttara-khaṇḍa of Śrī Padma Purāṇa.
